I have a 58 cadillac my parents bought in 1960. Lifelong Southern California car, i was 1 year old then. Being a car nut since birth, I loved this car, and in 1982 mom signed it over to me. The jetaway was leaky for years, but in 2011 it became a gusher! Finding a complete rebuild kit was easy. Finding a shop to do the work was a nightmare! Every shop i called, including AAMCO, said OH NO. Wouldn't have a clue how to do that one. Finally a shop about 10 miles from home said, yes we can do it. They had the car about a month. Only charged me 800 dollars ! 12 years later its still shifting fine ! No leaks! Enjoyed your video . Thanks.
These are very smooth transmissions. I have built many of these in my earlier years. The rear pump enabled the push/tow to start ability was discontinued in 1959. We called them "controlled coupling" or just CC. My first transmission school was on the 1960 Pontiac. This was at the G.M. Training Center in Hapeville GA. I was Transmission man in the Pontiac dealership. I graduated from this class on my 20th birthday. I am now 77 years old and still working. I just finished building a TH 350.
Reggie B didn’t they use a different oil back then, not dexron but a clear seal blubber derived oil or something? I did have a 59 Buick with the dynaflow but I never got to see inside it,obviously they’ve got a reputation.
@@ceciliapolicarpio1822 The fluid was designated ATF and all GM and Chrysler cars used this fluid. It was replaced by the Dexron. Ford used a fluid just called type F. it had more friction ability. If we had a GM Transmission with a little slip we would put type F in to help.
Reggie B Where can I find parts for a 315 jetaway. I have an all original 64 Bonneville 2 door hard top. I had a guy tried to rebuild the transmission many years ago and he failed. So it's just been sitting in a garage.
@@kerryrambo3503 1964 was the last year of the Jetaway. anything from a 1959 to a 1964 parts will work in it. I have a 1956 Eldorado with one of these transmissions. The 56 thru 58 is the same. They changed in 59. What is the Issue with yours? I might be able to give you some pointers. Where are you located? I am in northwest Alabama.

I love the idea that you share this information freely. That's the way all automotive technology should be. You are a truly talented guy, best regards.
I Have been in the Trans business for over 37 years and i just tore down a 1957 AMC Jetaway. Thanks to your video it went just fine so thank you and also thank your uncle. Have a good day. Paul's Transmission & Repair Baker City, Oregon.
..Totally amazing!! Beautifully done!! The '62 Cadillac I sold to a local older car guy in Sept 2021, had this same transmission, give or take a few differences! Fell in love and became fascinated with this unit shortly after finding out it was a Dual Coupling/Controlled Coupling HydraMatic Jetaway..Just had to learn more about it!! Mind had a half-moon cover plate with a thumbnail cutout vent under the belllhousing, held by cap screw/bolts, so the fluid coupling could be "6 o-clock positioned" to open the torus drain plug to drain the coupling!! Fascinating unit! My '62 shop manual showed all the parts broken down/extricated from the unit as you would attempt to rebuild it! Yes, that part he(Hiram) had trouble separating was, i believe, the front unit controlled coupling, which fills & exhausts for each other gear shift. Totally a fascinating unit and video!! Can't wait for Part 2..Thank you Hiram!! Your skill-sets amaze me!!
This is fascinating! I remember these transmissions but never saw inside one. This excellent video got me interested in how they work. I now have some understanding of the differences between the older Dual Range and the "newer" Dual Coupling 4 speed hydramatics. The power paths in the various gears is so interesting. Thanks for sparking my interest!
I am a 85 year old Korean war veteran who was trained in Hydraulics , pneumatics, for flight controls and rudder boosts systems. worked on B-29's a lot, some of them had track's on the main gears for landing and take-offs in the desert. some of the aircraft were Hydraulic nightmares, almost all the fighter jets made by North American had dual systems on everything, such as #1 and @2 flight controls, plus the utility system for brake's, flaps, and power steering. of all of them I think the F-100 Super Sabre was the worst. after the war I got out and trained as an automatic transmission specialist. this young man in this video is a very skilled specialist, he is dealing with a unit that was built and became obsolete before his time and I must say he is doing a great job of it. the hydromatic transmission's before this model came out did not have pans on them but they did have the Fluid coupling drive. and the 53 models were fitted with the Buick Dynaflow transmissions which took some clever redesigning. as the Buick's had closed drivelines in that model like the Chevrolet's prior to 1955. but the Old's and Pontiac's had open drivelines.
Hiram... Man I just started watching your videos this week... Thank you for keeping it real... And passing your massive amount of knowledge to the next generation of gearheads.... I'm amazed at how things progressed through the years... God bless you brother!
what are the odds. my buddy has one of these apart and waiting on parts. He said he's been building transmissions for 41 years and it's been a very long time since he has ever seen one of these. The fact that I seen one in person and I watch your channel on a regular basis and see one here in the same week. it's pretty cool to me. keep up the great work man!
The thing that wouldn't come apart was another fluid coupling; that was full of aluminum fins that used to get destroyed by the torque. That where the metal came from, and its unfortunate that you couldn't. Even more unfortunate that the pump was that worn (that was common when the fluid coupling got worn out). That coupling was filled and exhausted during shifting to smooth it out. Thank you so much for this trip down memory lane. I used to do a few of these when I was a kid, along with the Ford-o-matics and Glides. I used to restore cars and loved this old stuff. So much easier than 8 and 9 speed transmissions! Thanks again
+Mark Naravas I did get it apart, looks good from the inside. Fins okay. The snap ring popped out. I'm trying to get just the aluminum part since a lot was scrapped off. Otherwise I'll need to get the complete torus. And of course the pump.
Automatic Transmission Well, I'm glad you got it apart. But normally that's what gets destroyed in those. First one I've seen that needed a pump on a while. Might be a B@@tch getting the torus and pump. A small tip that might help you. I put one half of the coupling in the freezer and the other half in the sun for a while to slip the halves together. Hope the endplay is ok when you reassemble it. However, you're an excellent tech so I'm sure you don't need any help. I appreciate all the things you've done on your channels over the years. And have you gotten into any of the 8,9, or 10 speeds yet? Thanks again!
Thank you Hiram for the video, I have been missing these videos. I am glad that your still going on. Hope that you are blessed! As I was watching and seeing that it was not coming apart as it should, and i found myself saying come on outta there pilgrim.
Hiram you do a very good job. Especially for us, those who learn a lot from you, from your videos. I learn and understand very much about automatic transmissions from you. I'm from Romania, where most of the cars have manual transmissions. I learn also facts, solenoids,valves, from the DSG transmission by VW, which is commonly to us, especially on vw Passat or Skoda Octavia 2.0 TDI 140 HP. Greetings from Romania Hiram!
Hiram sir...because of ur experience n talent you dismantled this tough transmission, you r the expert. Thanks for sharing...also will see the re assemble soon 🤗🤗
dude you're freaking awesome I first came across you months back e4od issues anyway ended up having had thing rebuilt wish you could have done it anyway man God bless have a good day
muy bien senor.thanks for bringing back the days when i was in auto tech early 70s.hydraulics at the time were simple but somewhat complex,moved on to industrial engine and related things.excellent vid showing the parts and when cars were cars.
I saw your channel by chance about year ago when I tried to fix my 91 Explorer A4LD, and I saw more than half of your videos that time. And now I can say only "Thank you very much, Hiram!" Please, make more videos
Thanks for the video! This has been very helpful in my situation. The fellow who dissembled my Jetaway Cadillac transmission is no longer around and we are having trouble attaching the rebuilt transmission to the engine. That person did not mark the four critical studs as you did in your video. I would appreciate you posting the video of the process of attaching transmission to the engine. Thanks again!
I just recently found your channel. You are absolutely amazing at the work that you do. Your videos are very helpful and I hope you continue to make many more videos. Thank you!😀👍
My first car was a 1955 Chevy Bel Air 265 V8 with Powerglide. It could be push started. Back in that day, I could barely afford gasoline let alone a new battery! Luckily I had a friend whose car would start and he would push start me until I finally saved up enough to buy a used battery!
this reminds me of just how long ago I started doing transmissions, I have done a few of these in my time. I remember doing a few dynaflow back in the day also
Really nice touch with the screen in the upper right hand corner to get a wider and different view of the action in addition to the regular close-up view. Maybe it's just me, but it seems like we've got it a lot easier nowadays building 4L60-Es and such than transmission rebuilders had it ba
Sorry, trying to type this on my phone and my comment got cut off. Maybe it's just me, but it seems like we've got it a lot easier nowadays building 4L60-Es and such than transmission rebuilders had it back then with trying to rebuild these units. Don't know if I'd have been able to cut it on transmission rebuilding if I'd tried it back then. Glad to see you're back making videos.
My family had old Buick Roadmaster, maybe '53 or ''54, which could be push started. Very handy to have that feature in a car, unlike the modern auto transmissions.
Hey hiram I love your videos. I work as a diesel mechanic and we don't usually rebuild transmission but every now and then we do, but we only work on Dodge, Gm, Ford transmissions. I watch all your videos even though I don't work on gas vehicle transmission. I love to watch you work. The way you tare down transmission is amazing, you have so much knowledge on transmission. It's fun to watch someone who's a master at their craft work. Thank you so much for your videos. I watched your videos before I rebuilt my first 48re and I just go done rebuilding my first 5r110, that I will be installing next week. Also just wondering have you ever rebuilt a Ford 6r140 and if you ever run across one, it would be awesome to see you rebuild it. I only ask because I own a 2011 f250 and one day I would like to rebuild it myself. Thanks for your videos.
+dnm20101 6R140's are good units so far. I've replaced solenoids on those units when they start actin up. They're available through Ford, you just need to identify it correctly. In a few years I think they will be as popular as the older units.
I had a 1964 Pontiac Star Chief, one of the last two car models to use this transmission. Around the time I sold the car, it was having trouble getting into reverse. I made sure to park the car pointing uphill so I could roll backwards if I had to.
The 1-2 and 3-4 shifts are power-shifts. The engine slows down over about 3/4 of a second while the seat pushed you in the back. The second fluid coupling fills and bypasses the torque around the from reduction planetary. After second, the back planetary shift the high range and the second fluid coupling now drains to give you third. If it stays full, you go from 2nd to 4th.
Hey Hiram hope all is well! Been watching the news and Houston has been devastated by a hurricane.Hope you and your loved ones are well God Bless Carnal!!!
Hiram, thanks for the videos. They've been a lifesaver for me. Is there a part 2 on the jetaway 315? I need more info on governor removal, inspection, and reassembly. Thanks again
I enjoy watching your videos on my lunch break. I especially liked this one. It was obviously your first jetaway. You really wanted that shaft and assembly to come out of the rear. I've never been brave enough to make a video myself so I can't laugh too loudly, but I did get a chuckle out of your effort. You figured it out without breaking anything though. Did you ever put it back together?
Parabéns! Sou do Brasil e acompanho seu canal. Teobaldo do canal TEOMAVE que falou sobre você. Também estou começando a trabalhar com transmissão automática. Estou aprendendo muito com você. Muito obrigado!
Did a very similar transmission as a senior in high school auto shop in 73 on a 62 F-85 with the aluminum V8. We called the fluid coupler a torus. IIRC it had two exhaust valves on the exterior chamber where the fluid could be dumped then the proper clutch pack applied and then it was filled with fluid again for the shift. Front pump has an external spring driven variable displacement system where pressure build up would move the outside 'ring' such that the pump would not waste energy pumping excess fluid. Might be the weak point in the design because internal leakage would then equal direct heat build up in the fluid. My kit was robbed of the two main passage conveyors between the pump and the valve body, we had to make do with fuel hose substitute because the parts house denied stealing anything out of the 'new' kit we bought from them. It quit after 6 months, when I pulled the pan to see what I could see, there were both sections of fuel hose laying loose. How they could escape total entrapment like that I still can not fathom. They appeared to be pristine too, should have been ragged up to a horrible extent. Should have kept that one, trade in value for another used car was $40. This one appears to be a good deal different, so now I'm wondering what I was working on so very long ago in another time and place?
Hiram get a lifter crane off wall to lift heavy stuff. Save your back. Harbor freight has one for pickup truck bed. Attach to wall beams behind bench. Awesome channel! Look foward to each one. Ps my buddy on Long Island has a trans shop. He cannot find workers to train to build. Can you find guys?
Hiram I watch your videos and it’s amazing the knowledge you have. I thought maybe you could help me, I’m buying a used suv and last time we did we bought a 2009 Saturn Vue and the transmission went out immediately, is there an suv with a very durable and reliable transmission- any help would be greatly appreciated
My transmission cooler seems to be the exact opposite with a newer model Jetaway. The transmission actually pumps its oil through the radiator and pulls it back. Odd how only eight years can make such a big difference in the type of cooler.
How many parts in this transmission ? Hiram might have taken one of these apart before this one, right ? I'm thinking an adpater and 700R4 seems pretty appealing at this moment.
Hiram,so good to see how a professional will attack these ancient Hydramatic transmissions. I have a similar unit in my '64 Bonneville that I'm having leakage issues with when under storage but I can't see where it's coming from. Engine is currently out so I'd like to adress the situation, what I'm missing is a clip where you're putting this tranny back together again
I have a 1960 pontiac Jetaway 315 partially disassembled in my garage. The tool to get the front coupling apart is hard to find, so I had to improvise a puller myself.
Mr Hyram, getting a little off subject here but did you ever do a Allison AT545 4 speed auto trans rebuild? I have searched youtube and no one has ever done one.
can you do a couple videos of the MD8 transmissions and the differences between that casting / valve body and the differences of the internal components? I've called around and tried to find out but i cant seem to get a good answer! My truck came with a MD8 transmission and there are some things that i would like to do to it to make it more fuel efficient via putting a and overdrive system on it! not even sure if it has one or not and if it does weather or not if it works or not! things like that!
Do you happen to have any videos of the teardown and rebuild of a GM 4T60E transmission? The ones w/o the vacuum modular. Or videos for the transmission GM used in the 97 - 2005 MALIBU
There are some thrust washers in the front coupling unit that can wear and cause excessive end play. Either the fins will clash destroying the coupling or the snap ring comes off. Coupling and pump damage is the result.
Hello, I have a question, my 04 vw beetle 2.0 with auto transmission has been doing this issue when it is cold where it sort of bangs into first gear, other gears are fine. When the car heats up the issue stops completely and it shifts perfect. What would it be? thanks, I like your videos.
Hi i have cadilac 1957 with the same transsmition the 3rd gear don’t came when the engin cold when be hot after 15 min the 3rd gear come simple Whte is the problem?
Just watching all your videos I just wanna send my transmission to be rebuilt by you. I'm sure if I take it to a repair shop they wouldn't replace parts like you do that will cause issues in future. Can I send you my trans?
315 parts are really expensive. You can spend $600 on a master kit, and bushing kit. Not counting your pump and other hard parts you need! I hope it's a nice 57 Caddy, cause that's gonna be a pretty big bill!
Hey sir I have a 2012 dodge 4500 truck every time I put it in gear it killed the motor in drive in back it back up I took pan down it have no shaving in the pan can u get back with me to guide on what I have to do
Hi Hiram, 5R55S question. Doing a complete rebuild. Can you do a vid or a post for what you would do additionally for new parts. Your get it oiut the door 3 part 5r55s vids are GREAT ! but if we do a rebuild we might miss a detail needed for all new parts on this iffy tranny. Thanks, Ron
I have a 1956 Oldsmobile 88 with the jetaway. No transmission shop wants to touch it. What was the big problem with these transmissions?? Or was it just the 1956 because it was the first generation for that trans so it wasn’t perfected yet???
I also had trouble finding a shop to do my 58 cadillacs jetaway. Finally did, they did a great job. Still shifting fine. A few year later, i stopped by to say hello and the shop was gone. The business next door told me they moved Out of state. Dang! Hope i never have problems with it, will be back scrounging around for a shop that will touch it again! Hopefully you found someone to fix yours.
@@johnfranklin5277 hey John. I indeed found an old transmission shop about 7 miles away from me. These guys have been rebuilding transmissions since the late 50’s. I got so lucky with them. Good ol Jim rebuilt my JetAway in a about 2 days. He told me what the common problem was with the 1st generation JetAway then replaced that with the upgraded part. I’ve been driving my ‘56 Olds as my daily driver ever since. There’s nothing like warming up an American Classic for 3-4 minutes every morning.
@@jasondean3332Hey Jason, Very glad you were able to find a shop to rebuild your Olds transmission! Its definitely tricky trying to find mechanics to work on these old girls. Today's ASE guys just look at it as if its from another planet. Can't even install points. Carb rebuild...forget about it! Lol. Enjoy your ride, I'll be taking the 58 out for a little Thanksgiving cruise...😊
hey bud, I noticed you haven't posted any new videos in a while. I hope you are enjoying life and doing your own think vs some of the alternatives! however, if you could let us know you're alive and well, your youtube fans would greatly appreciate it :)
@ 46:05 that friction plate is actually called a "neutral clutch".. @ 55:04 you can see the inside bottom of the case there is an alignment pin that keeps the one drum from rotating. it's inserted to a hole in the case. if he does'nt pull it out now he'll lose it in the wash. without it it's disaster time.
Buick never used this transmission. Buick used the Dynaflow from 1948 thru 1963. The the Super Turbine 400/ Turbohydramatic 400 came out . But thbkkfully it was a completely different design from previous Hydramatics.

Very interesting. Several comments about the push-start capability. Don't forget that it also could be towed with the wheels down.
+Dave Caselli yes, that was a plus since the unit was lubricated from the auxiliary pump.
My family had old Buick Roadmaster, maybe '53 or ''54, which could be push started. Very handy to have that feature in a car, unlike the modern auto transmissions.

Hiram, you are the MAN my friend!
Gracias por el video volvi a mi juventud un poquito
Hey hiram I love your videos. I work as a diesel mechanic and we don't usually rebuild transmission but every now and then we do, but we only work on Dodge, Gm, Ford transmissions. I watch all your videos even though I don't work on gas vehicle transmission. I love to watch you work. The way you tare down transmission is amazing, you have so much knowledge on transmission. It's fun to watch someone who's a master at their craft work. Thank you so much for your videos. I watched your videos before I rebuilt my first 48re and I just go done rebuilding my first 5r110, that I will be installing next week. Also just wondering have you ever rebuilt a Ford 6r140 and if you ever run across one, it would be awesome to see you rebuild it. I only ask because I own a 2011 f250 and one day I would like to rebuild it myself. Thanks for your videos.
+dnm20101 6R140's are good units so far. I've replaced solenoids on those units when they start actin up. They're available through Ford, you just need to identify it correctly. In a few years I think they will be as popular as the older units.
I had a 1964 Pontiac Star Chief, one of the last two car models to use this transmission. Around the time I sold the car, it was having trouble getting into reverse. I made sure to park the car pointing uphill so I could roll backwards if I had to.
The 1-2 and 3-4 shifts are power-shifts. The engine slows down over about 3/4 of a second while the seat pushed you in the back. The second fluid coupling fills and bypasses the torque around the from reduction planetary. After second, the back planetary shift the high range and the second fluid coupling now drains to give you third. If it stays full, you go from 2nd to 4th.
Hey Hiram hope all is well! Been watching the news and Houston has been devastated by a hurricane.Hope you and your loved ones are well God Bless Carnal!!!
Thank you great video
Hiram, thanks for the videos. They've been a lifesaver for me. Is there a part 2 on the jetaway 315? I need more info on governor removal, inspection, and reassembly. Thanks again
Automotive archaeology. Keep up the good works.
+Chris Bamford Hmmm, sounds like a good title.
Hiram, we miss you man!!!
You are The best
Dont stop
I enjoy watching your videos on my lunch break. I especially liked this one. It was obviously your first jetaway. You really wanted that shaft and assembly to come out of the rear. I've never been brave enough to make a video myself so I can't laugh too loudly, but I did get a chuckle out of your effort. You figured it out without breaking anything though. Did you ever put it back together?
Great video, where's the rebuild? Anyone know if ANY other jetaway 315 videos? My caddy is stuck in 1st gear
Parabéns! Sou do Brasil e acompanho seu canal. Teobaldo do canal TEOMAVE que falou sobre você. Também estou começando a trabalhar com transmissão automática. Estou aprendendo muito com você. Muito obrigado!
+Auto Tech Service Saludos.
Hiram, desculpas por não falar meu nome kkkkk. Meu nome é Daniel. Obrigado!
Meu nome é Daniel. Peço desculpas por não ter dito antes.
Love your vids... I wish you'd do part 3 of the 350...
THANK YOU
God, this guy knows all the automatic transmission that exist in the market
Did a very similar transmission as a senior in high school auto shop in 73 on a 62 F-85 with the aluminum V8. We called the fluid coupler a torus. IIRC it had two exhaust valves on the exterior chamber where the fluid could be dumped then the proper clutch pack applied and then it was filled with fluid again for the shift. Front pump has an external spring driven variable displacement system where pressure build up would move the outside 'ring' such that the pump would not waste energy pumping excess fluid. Might be the weak point in the design because internal leakage would then equal direct heat build up in the fluid. My kit was robbed of the two main passage conveyors between the pump and the valve body, we had to make do with fuel hose substitute because the parts house denied stealing anything out of the 'new' kit we bought from them. It quit after 6 months, when I pulled the pan to see what I could see, there were both sections of fuel hose laying loose. How they could escape total entrapment like that I still can not fathom. They appeared to be pristine too, should have been ragged up to a horrible extent. Should have kept that one, trade in value for another used car was $40. This one appears to be a good deal different, so now I'm wondering what I was working on so very long ago in another time and place?
Hiram get a lifter crane off wall to lift heavy stuff. Save your back. Harbor freight has one for pickup truck bed. Attach to wall beams behind bench.
Awesome channel! Look foward to each one.
Ps my buddy on Long Island has a trans shop.
He cannot find workers to train to build. Can you find guys?
+motorhead I was thinking of something like that, too. I will consider it.
Hiram I watch your videos and it’s amazing the knowledge you have. I thought maybe you could help me, I’m buying a used suv and last time we did we bought a 2009 Saturn Vue and the transmission went out immediately, is there an suv with a very durable and reliable transmission- any help would be greatly appreciated
My transmission cooler seems to be the exact opposite with a newer model Jetaway. The transmission actually pumps its oil through the radiator and pulls it back. Odd how only eight years can make such a big difference in the type of cooler.
Could you tell me what component siezed it the torus rear cover won't rotate..front pump? My 57 strato flight locked up but only the torus shell
How many parts in this transmission ? Hiram might have taken one of these apart before this one, right ? I'm thinking an adpater and 700R4 seems pretty appealing at this moment.
Enjoyed that. Did you find the parts you needed? Hope you are ok?
Hiram,so good to see how a professional will attack these ancient Hydramatic transmissions. I have a similar unit in my '64 Bonneville that I'm having leakage issues with when under storage but I can't see where it's coming from. Engine is currently out so I'd like to adress the situation, what I'm missing is a clip where you're putting this tranny back together again
Have you thought about mounting a camera above the bench? Great video. Thanks
I bought a 57 Powerglide kit from a place called Fatsco. Specializes in old trans parts.
+John Farr That's where this kit came from. Out of California.

I have a 1960 pontiac Jetaway 315 partially disassembled in my garage. The tool to get the front coupling apart is hard to find, so I had to improvise a puller myself.
great video, are we going to see a part 2 soon?
Nope......
GREAT SHOW! i have been waiting for a 50's transmission scince i subscribed. the suspense, will he find the hard parts? on to part 2
Push starting isn't common now, but back in those days, batteries sucked compared to now, so you had to push start.
Very good vídeo
Mr Hyram, getting a little off subject here but did you ever do a Allison AT545 4 speed auto trans rebuild? I have searched youtube and no one has ever done one.
can you do a couple videos of the MD8 transmissions and the differences between that casting / valve body and the differences of the internal components? I've called around and tried to find out but i cant seem to get a good answer! My truck came with a MD8 transmission and there are some things that i would like to do to it to make it more fuel efficient via putting a and overdrive system on it! not even sure if it has one or not and if it does weather or not if it works or not! things like that!
Do you happen to have any videos of the teardown and rebuild of a GM 4T60E transmission? The ones w/o the vacuum modular. Or videos for the transmission GM used in the 97 - 2005 MALIBU
Being an automatic transmission builder do you drive manual or auto?
There are some thrust washers in the front coupling unit that can wear and cause excessive end play. Either the fins will clash destroying the coupling or the snap ring comes off. Coupling and pump damage is the result.
thanks for this ...
Did you get this finished?
Hello, I have a question, my 04 vw beetle 2.0 with auto transmission has been doing this issue when it is cold where it sort of bangs into first gear, other gears are fine. When the car heats up the issue stops completely and it shifts perfect. What would it be? thanks, I like your videos.
This unit has to weigh more than most modern engines do.
What is the difference between 2010-2009 Chevy Impala transmission and a 2007 Impala transmission?
ótimo video
Hi i have cadilac 1957 with the same transsmition the 3rd gear don’t came when the engin cold when be hot after 15 min the 3rd gear come simple
Whte is the problem?
Hey man, what's the best way to get in contact with you privately? Got a nissan skyline sedan 350gt auto import cvt8speed with transmission problems.
What happen to the video of this transmission. I didn't get to see you put it back together
Good Job
Just watching all your videos I just wanna send my transmission to be rebuilt by you. I'm sure if I take it to a repair shop they wouldn't replace parts like you do that will cause issues in future. Can I send you my trans?
Where is the build up video for it? I am curious to see if you got the parts and how it went back together.
315 parts are really expensive. You can spend $600 on a master kit, and bushing kit. Not counting your pump and other hard parts you need! I hope it's a nice 57 Caddy, cause that's gonna be a pretty big bill!
Nice!!!
Hey sir I have a 2012 dodge 4500 truck every time I put it in gear it killed the motor in drive in back it back up I took pan down it have no shaving in the pan can u get back with me to guide on what I have to do
What kind of solvent do you use in your parts washer?
Hiram did you get deported? where did you go?
Hi Hiram, 5R55S question. Doing a complete rebuild. Can you do a vid or a post for what you would do additionally for new parts. Your get it oiut the door 3 part 5r55s vids are GREAT ! but if we do a rebuild we might miss a detail needed for all new parts on this iffy tranny. Thanks, Ron
hello i like yours videos. could you tell me where i can see you because i have 2 cars that i need you repair thanks. i live in LA
Where is your shop located?
I have a 1956 Oldsmobile 88 with the jetaway. No transmission shop wants to touch it.
What was the big problem with these transmissions?? Or was it just the 1956 because it was the first generation for that trans so it wasn’t perfected yet???
I also had trouble finding a shop to do my 58 cadillacs jetaway. Finally did, they did a great job. Still shifting fine. A few year later, i stopped by to say hello and the shop was gone. The business next door told me they moved Out of state. Dang! Hope i never have problems with it, will be back scrounging around for a shop that will touch it again! Hopefully you found someone to fix yours.
@@johnfranklin5277 hey John. I indeed found an old transmission shop about 7 miles away from me. These guys have been rebuilding transmissions since the late 50’s. I got so lucky with them. Good ol Jim rebuilt my JetAway in a about 2 days. He told me what the common problem was with the 1st generation JetAway then replaced that with the upgraded part. I’ve been driving my ‘56 Olds as my daily driver ever since. There’s nothing like warming up an American Classic for 3-4 minutes every morning.
@@jasondean3332Hey Jason, Very glad you were able to find a shop to rebuild your Olds transmission! Its definitely tricky trying to find mechanics to work on these old girls. Today's ASE guys just look at it as if its from another planet. Can't even install points. Carb rebuild...forget about it! Lol. Enjoy your ride, I'll be taking the 58 out for a little Thanksgiving cruise...😊
Great video, do you have the assembly video?
the reverse of tear down...durrrrrr
hey bud, I noticed you haven't posted any new videos in a while. I hope you are enjoying life and doing your own think vs some of the alternatives! however, if you could let us know you're alive and well, your youtube fans would greatly appreciate it :)
@ 46:05 that friction plate is actually called a "neutral clutch".. @ 55:04 you can see the inside bottom of the case there is an alignment pin that keeps the one drum from rotating. it's inserted to a hole in the case. if he does'nt
pull it out now he'll lose it in the wash. without it it's disaster time.
Buick never used this transmission. Buick used the Dynaflow from 1948 thru 1963. The the Super Turbine 400/ Turbohydramatic 400 came out . But thbkkfully it was a completely different design from previous Hydramatics.
Nice one. Anyone who knows what happened to Craig Fietsams channel? He also made excellent videos about transmission rebuilds... thx for sharing.
