Tremec T56 - 6 spd Trans Rebuild Homemade Trans Jack & New Project
Вставка
- Опубліковано 10 лис 2015
- I'll show you what makes them difficult to shift into 1 & 2nd gear plus the tricks to repair and re-assemble them. If you need a trans jack check out the homemade setup. Also included some extra car info and what I've been up to in general! I like buying things that need some work - then when one goes thru everything you know what you have. Hope you don't mind the longer video instead of the 2 part thing. Leave a comment or ask a question! Thank you all for watching, Jeff

This guy seems like such a cool dude. I would totally just hang around his shop and listen to what he has to say.
I Thank you Nicholas, Jeff.
Thank YOU for making this video. It has taught me a lot I did not know before. Decided to go with a TKO 500 instead of the T-56 but the knowledge here is still greatly helpful.
he knows his shits and keeps it real
dude i wish you were my neighbor. awesome video.
Thank you for this great video Jeff. By far the best video come tent for rebuilding a manual transmission. This makes me want to dive into mine but I believe it is still beyond my skill level. Your skill level abd expertise definitely shows, great job👍!!! Appreciate all the helpful tips, thank you.
Man who ever is his neighbour got sooo lucky. If I was there he would never have to buy beer again.
Very good tutorial and commentary, gonna get into my T56 soon. Thanks
Thanks for the video, I'll use your tips when I get a T56 to rebuild for a project car.
Great video man, T56 is one of my all time favorite Trans to work on. Getting ready to pull mine out of my 97 Comp T/A Build #154 and rebuild it. Only 55k miles but I'm starting to get the infamous problem of it jumping out of 2nd Gear. Never accrued to me to mark for the guide pins, I've been lucky and haven't had that much trouble with them in the past. But its something I'm going to do from now on.
Very good tips , great work .
thank you for this video. I have no fear building a motor but transmissions have always scared me. now that I've watched this I am actually excited to tear into my t56!
+Chase Langs Hi Chase. Just lay things out in order, take your time and mark if necessary. Some parts look like they could be inverted until close examination. It's neat to be able to say you did things yourself and all works perfect the first time!
Nice job and thanks for the extra tips as you went bud. ✌🏼
thanks for sharing.great video.great work.
great video. awesome job explaining things. You are true enthusiast mechanic, Cheers.
+1gbayfisher Thank you!
Good job taking the time to clearly spell things out. Awfully nice of you!
Thanks for the vids this one especially as I want to put a t56 in to a 560sec but can not pay for a new one, so this will be a big help for me keep the vids coming nice work.
+gck82s Thanks! Glad to be helpful. One can save lotsa $ by doing things yourself. That's what made it possible for me to get here!
Good job man 👌👌
Very well done.
Great video as usual Thanks Jeff!
+John Wallace Thanks John. Try to keep the vid flowing - don't want it to seem boring. It's amazing on how technology advanced so fast on video and automotive. :>)
+2jeffs1
Yea but that feeling when you spread out a layer of silicone and barely get any ooze when assembled ;)
Thanks for making this video with tips and advice. I plan on rebuilding my T56 soon. It grinds 3rd and 4th.
+sierravmax Thank you sierravmax. I was hoping to receive such a comment where someone was going to tackle one of these after watching the video. I tried to include many of the little details to make that job a breeze!
I am having the same problem with my 97
pink Floyd in the background makes this video even better
+alain robles Went to see them in concert in 1977. What a great time - and still have the ticket stubs... :>)
Great job 👍😃
Always love your videos!
+Dan Robidoux Thank you Dan. Had a lot of time in putting this one together doing multiple takes on each scene and pick the best one in the edit room. Ahhh - gotta add to the confusion at my end!
2jeffs this video made a subscriber out of me. keep wrenching. God Bless U
Hi Ronald. Many more tweaks and tricks to come. So much appreciate reading the comments and by the way - thank you for the sub too!
Nice quality work.
+57WillysCJ Thank you! I enjoy doing any kind of automotive work. It seems to be more of a hobby than a job.
Nice through video..thanks
Best video I've seen yet on the T56! I'm about to do what amounts to a FULL rebuild of the transmission, minus only shafts and gears, in my 2002 Z06 Corvette. It's a track car with almost 100k mi on it. The diff is giving out on it, and while the transmission feels pretty decent right now, I may as well just deal with both while I'm dropping the entire driveline! Unfortunately, I can't really service the Getrag diff without a bunch of really expensive, proprietary tools. I'm going to have to outsource that job. However, I can't wait to break open my T56 this weekend and scope it out!
Thanks!
Sounds like quite the project you've go going on there! Take your time, double check everything and you'll be good to go!
Great video
I had a 99 Firebird with a 5 speed. I always wanted a T56-6 Speed for it, but alas my wife made me sell it because it did not have back doors. Grinn.... I have never owned an automatic car, and I would have loved a T56. BTW, When I sold it last year the transmission was like new. I have never blown up a manual transmission yet, and my synchros were good in all gears. I rev match all up and down shifts, and when it is cold I double clutch into 2nd gear for the first couple of minutes. Most guys just jamb it and pay the price. Many years ago (I'm dating myself) I factory ordered a 76 Pontiac Ventura with a V8 and a 5 speed. That year there were five of them ordered in my city and all got destroyed in the first year. They said those Borg Warner 5 speeds were a weak transmission. I sold mine 19 years later because it was totally rusted out, but that Borg Warner "weak transmission" was still perfect. Four years ago I bought a new 2014 Chev Cruz with a 6 speed of course. I don't know how long that little 1.8 four banger will last, but I expect the 6 speed will last the life of the car, because nobody, but nobody drives my manual transmission car. Shifting a stick today is a lost art.
If that’s a ws-6 then that’s a rare color for that car. Hate to see her lose her drivetrain 😬. Lol. Anywho, great info! Thx for that. I’m thinking of buying a t/a w/a 6spd that cant go into 5th gear. Great info. Think I can tackle the trans rebuild myself. 👍
Great video very helpful 👍🏻👍🏻
+Ricardo Vazquez Thank you Ricardo. Those are the words I hope to hear!
Great transmission. I'm putting one into my truck. So much better than a 4L60E.
great vid
Great job.
+Keith Gardner Thank you Keith.
Mate, you're a legend. Common knowledge is hard to find and by hard to find I mean you are the easiest to understand. :P
Thank you very much for your kind thoughts!
thank you this video was very helpfull.
+Nick Berend Thanks Nick. These are quite nice to service v/s some other kinds I've done in the past.
Is this Ray from Ghostbusters? Lol
Good vid. Thx
Awsome car and vid
+John Gibson Thank you for your comment John, glad you enjoyed.
Hey mate, awesome tips and advice here, loved it, wondering what transmission fluid you use when servicing these t56s, recommendations says to use dex III but I live in a hot area all year around, thinking might be a better substitute around for more heavy use and heat, thanks a lot mate, keep wrenching !
Thank you for all the information on video. i now know that rebuilding my transmission is still a little out of my league from an equipment, tools and expertise perspective. From watching though, I think I have diagnosed a 3rd-4th shift fork bend or break problem. Thank you!
I do like when people take the time to leave a comment about what their up to and this video helped out! Thanks for stopping by Mark, Jeff.
Very cool video! Btw, what kind of shop press would you need for this? I'm having my T56 rebuilt right now, and the guy told me that most transmission shops don't rebuild manuals because they're rare and because they would need a shop press. If I wanted to do this on my own, what kind of specs should I look for? Thanks!
You would be the dream neighbor, could learn a lot from having a neighbor lile you
wow awesome video wish you were my neighbor lol
Look nice
Good video..Thanks
+rickboh Thank you for stopping by!
Nice bird man! how about doing the interior ceiling looks like its coming down.
Somebody get this guy his own show on Velocity!
"Just cause you gotem all don't mean you need em".... lol, I like it
I do first third fifth in my truck
+dinny7777 With the rev limiter set higher all one needs is first and sixth! Well maybe? :>O
Great video, sure does take the mystery out of the manual transmission. Thank youDid you set the end play of the cluster and main shaft? If so, will you explain your methods?
No, just re-assembled same way. All was good as is.
ned flanders is a pretty good mechanic
Really excellent video Jeff. You have a great way of explaining everything with the correct terms, and lots of skill obviously. Neat tricks too.
I've got a C5 ZO-6 and it shifts very well, but in a week I'll be test driving an '07 CTS-V and the owner has made some mention of the trans being sticky into first. Car only has 30k on it - any advice as to how to determine if the Tremec in that V is in trouble? I know how to check for clutch drag, but I don't want to buy a problem!
Thanks for posting the video!
Up shifting the trans still worked pretty good. When coming to a stop getting into first gear was the big problem. When coming up on a 4 way stop and its your turn to go and your not able to get into first that is quite aggravating! (as you noted there was no clutch drag either) On an older 4 speed trans one could always work the clutch just right and easily get into gear no matter how tired the trans was. Anyway that would be a sign of upcoming repairs. Hope that helps ya out.
I've driven the CTS-V and have purchased it. First and second are very smooth and easy to engage. It pops out of reverse gently, mostly I think because the stock shifter is so sloppy. Reminds me of the old "Cornbinder Wobblestick" of the past! I'm hoping a short shifter will make the difference on the reverse engagement - I don't think it's getting fully into gear.
Thanks for the reply and the advice Jeff. Take care!
In your experience on the GTO T56 Tremecs... If grinding while shifting into 2nd, can you get away with just replacing the center friction cone? Or should inner and outer also be replaced. (These do not have the kevlar/carbon pads on them like the double-sided center ring, but do they get really get worn down much?) Also would it be worth trying to just swap out my fluid to GM Synchromesh? Not sure what is in there now... Bought it in this condition.
Me again two Jeff's
You read my mind man, just picked up a brand new T56 6 speed for my 69 Stang Mach 1. It will be bolted up to a 429 SCJ with 429 Boss Bulkheads
Hi Josh. Way cool, I bet you can hardly wait until the day you get it finished and get a ride! Is is so much driving a car with one of them in v/s the old 4 speeds!
Hi Jeff! after watching your video I am quite excited to take my T56 apart. It has the same problem like you had in 1st and 2nd. it sometimes does it in 3rd aswell. and almost never engages into reverse anymore. I've only done about 2000 miles on it since I bought it of craigslist. I'm wondering if this failure might have been caused by running the wrong transmission fluid or perhaps the B&M short shifter. At first I had Penzoil dexron 3 ATF in it and only recently changed it to GM synchromesh after the problems started shifting. what Oil do you recomend? and what do you think might have happened to 3rd gear and reverse? Your advice will be greatly appreciated sir! Thank you.
Don't seem right/not good where you just bought it and having problems already. First I am running the regular Dex 3. (Did do some research on that again some time ago.) Actually in the 70's I was putting that in manual transmissions and transfer cases before the manufactures were doing that. I enjoy experimental as you might gather. Things shifted great when below zero and never any related failures. I have tried the Dex 6 and gear oil in a bad working T56 to experiment to see if it helped at all. Actually think that made things a little worse. Wanted to include that cause I know someone was probably pondering doing that to save them the effort!! For the 3rd and reverse check the rings, syncro blocks, and forks over carefully after disassemble for wear and engagement teeth nose tips/ends. A little FYI - When I engage to reverse I do that while slightly moving and that seems to make it go in better than at a full stop. After all it has a syncro ring! You are probably aware of that reverse lock out. The factory setting from the computer keeps reverse gate blocked until under 2 mph. I did change my computer to 10 mph with that tuners program. I like being able to easily get into that gate in advance even tho not ready for rev yet - especially backing in a driveway on a busy road. That B&M short shifter - not familiar with that so sorry can't help. Just take your time and inspect the concern areas & assemble and you should end up being a happy camper, Jeff
Hay Jeff it’s Biffo from Australia 🇦🇺
First of all great vid 👌very informative 👏👏thank you for that
I have a Aussie vx ss Holden commodore
They come out with a LS1 tremac t56 same as yours
And it grinds and pops out of 3rd only going up the gears and under a bit of rpm
Going down shift under competition it will hold 3rd fine unless I trump it in 3rd
It’s is beautiful in every other gear including reverse
I want to have a go at rebuilding it myself and now after your vid I have a lot more confidence to tackle it myself
But I am not sure what I should replace
What do you think ?
Regards
Biffo
love the video very helpful, about to have a t56 rebuilt and its stuck in 4th gear will not come out with the car on or off, any idea what that would be before i dive into it?
Where they have that upgraded 3/4 steel shift fork kinda thinking the aluminum one might of failed/broke. Hope this helps out and good luck on your repair, Jeff.
Could you possibly put a parts list in a comment? My GTO has a similar issue. And it drives me absolutely crazy. I'd like to pull the trans apart, rebuild it, and replace the clutch system.
Jeff this is a great video! I have a 98 TA WS6 with the T56. 140k & the problems you mentioned. I did some racing back in the day and starting to get to work on my neglected street cars. I have rebuilt my Falcon transmissions in our dirt mod but was reluctant to tackle this project. With this video I think I'll give it a whirl. Your link to the parts store doesn't still seem to be up? Maybe because it's from a while back. Can you suggest a supplier? Thanks again for the great video!
Hi Rob. When I did that trans I dealt with a different company than normal. Salesman sucked, not helpful at all. Trans star is who I use to deal with if they are in business yet (things are changing so much these days) check with them perhaps.
Nice video and Thank you. Where did you get the two jaws for the end of the long tool you made?
Thank you Rich. Them were from an old power steering pump pulley puller. Can't remember where it came from. Might of been K&D tools.
I'm researching t56 trans, for my t5 upgrade. It will No handle the power from my stroker engine. I just cannot see swapping in a automatic! Unless it's maybe a 6L80e, but still, I'd rather have a clutch!!, any idea where to find a good deal. On a untouched T56?
Hi jeff, first time watcher, from the UK. Very informative video. I'm looking to make a gokart for my boy but i wanted to make it geared for me to play with when hes not there. That way I have more power to play with while my son can play relatively safely. Any ideas on which sort of gear system would be better? currently thinking of running it with a 600cc honda cbr engine or some such.
+Craig Blanchard Hello Crag. Many years back I built a kart with a narrowed car car rear end. I did buy the rear end which was crudely shortened by a guy. (was cheap & worked good) Then I bought 2 - 3 speed transmissions from the junk yard that the shifter came directly out of the top. (don't remember what they were from) Hooked them inline together with no driveshafts only the yokes & u joints. Had 9 gears forward and 3 speeds in reverse. Then put a 10 HP Briggs in front with a duel belt clutch. The frame and steering was all homemade. With both trans-es in 1 st gear top speed was 3 mph but the power was awesome. With both in 3rd gears app 45 mph was possible. That thing was great for all around uses. I do have 8mm footage of this thing but it's pretty grainy. Still might post it some day where folks like you would probably enjoy it. If there was a way for you to link a 3 or 4 speed trans with your setup you should have a similar setup, speed & power. Hope this helps you out with some thoughts, Jeff.
2jeffs1 I'd like to see that!
Would you happen to have a spare exciter ring for a T56 Magnum? if not do you know where I may be able to get one? I need to make one with half as many teeth for a special application on a Mazda Rx-7. Speedo reads twice the speed and I would rather modify the trans than the gauge cluster. BTW thanks for sharing the awesome tips!
No spare here. Probably check with a trans shop. Worse comes to worse a dealership could get you one...
where did you get that video scope?
His voice reminds me of Dan Aykroyd, not a bad thing
Jeff what fluid did you use in the trans ??
Hey, Man, nice video.
I'm looking for a kind of support located at the left side of the transmission that holds a support bar that ends at the differential holding bolts, but I don't know the name and that makes me hard to find It.
I own a 1997 Pontiac Firebird Trans Am WS.6 with a tremec t56 transmission.
its called a torque arm
Jeff can you recommend a rebuild kit for a 97 Camaro with an LT1 with T56?
Hi there! The kit I bought was kinda an overkill where the bearings probably would of been fine but I can't tie up the shop for my stuff, wanted to make sure all went good. Seems you can buy a more basic kit, syncro rings without the bearings and might want to consider several of the updated parts as shown on the video too. That rebuild kit I showed came from zbag.com/
great video. very interesting. I know nothing about transmissions, but i have heard that skipping gears can wear out syncros. any truth to that? I myself skip gears all he time.
+Tiit Saul I believe that is correct. When I do that I'll allow a bit of time before engaging the skipped gear or gears so the clutch disc has time to slow first to match the engine speed. Perhaps you caught how long I delayed the 6th engagement when the other gears were skipped - second to sixth. There is a different feel in the shifter when speeds are matched with the engine. Under those conditions the rings should last for the life of the trans one would think.
Thank you for the explanation. When I skip gears from third to fifth I still shift into fourth for a moment ( clutch still engaged). I think it helps a little bit.
Do you think a T5 transmission would be sufficient for a 327? I have a 72 Buick Skylark and a 327/quadrajet carb with a 2.93 rear end. My goal is to shoot for 25 mpg. Some say I would need a shorter rear end like a 3.55 so as not to be revving to the moon in city driving. What would be your take on this scenario Jeff?
I think that would be a good choice. They hold up great and with a lower rear gear you would have the best of all worlds. City and highway driving.
how u figure main shaft play?
Going back together with mine I get stuck in 4th. It seems the throw of the ring is too long (more than halfway past the synchro keys) and then it's too difficult to go back to center. I'm seating on my tapered bearing and in the key ways on my synchro ring... What limits the throw of the ring? Hitting the gear or the H pattern? Yours goes in and out of 4th effortlessly when putting the case on so I think something is wrong. I did have to use a puller to get the 3-4 hub off and I had to press it back on. It's flush with the snap ring so I don't get it. The distances from 3rd to center and 4th to center is pretty much the same (within .050"). I'm lost at the moment...
Anyone having the same problem, mine was from using a slider sleeve that wasn't tight enough on the hub causing it to be able to flop around in there (it was an aftermarket slider). I was also popping out of 3rd gear under decel. New matched hub and slider and no more problems.
You sound like Dan Akroyd
I just watched this again. So, do still have the Pontiac and how is the transmission?
Still have it and working great!
I gotta fix my second gear on my 1500 and now first gear it's goin the same route can you please let me know where you bouth the kit please thank nice video by the way
+alain robles The kit was bought from a place called ZBAG. They don't have a lot on their web site but if needed their salesman on the phone can assist you for your needs.
I have a 2004 cobra. My T56 keeps popping out of 4th gear. It does it maybe 3-4 times while I’m driving normally. But it goes right back in gear when I push the clutch in. What do u think that is? My car is pushing out 630 hp to the tire. Do I need to upgrade the gears or something? Thanks for any help u give.
The detents must be crisp which assist in gear retention but I more so suspect the teeth in the 3/4 syncro block slide collar or 4th gear where the collar - slide/contact area are worn.
Upgraded master cylinder fixes the issue almost everytime
Good job bro where u location?
My dad's got a 98 Z28 with the T56. It needs a rebuild as well. Was the steel shift fork a worthwhile upgrade?
Great question. Unless he is racing his car quite often, your right, probably not necessary and worth it.
No, he doesn't race. We just want to make sure it will last. Thanks for the reply.
What kind of puller is that
2jeffs1 Great video ! I am having the same exact issues with gears 1 and 2 but I’m not so sure I trust my skill level to fix myself. What should I expect to pay a mechanic for this job? Thanks
Hard to answer that. Depends on what they all end up replacing, etc.... I would try to find a friend who is happy with a certain place and they thought they seemed honest and offer to show you the replaced parts on pickup with a reason why they were replaced. Beware - I have seen people bid low to get you in the door and when taken apart they.... Also the cheapest bid usually ends up with a return visit for a re-do so beware.
where did you get all the specs for it? as far as clearances and assembly/disassembly? thanks
I use Michell manuals Those cover different trans/trans axle and transfer case, many models.
Just watched a 4L60E rebuild. This is a lot simpler.
Jeff should change his name to 2 Jeffs in 1. Hes having more fun getting things done!!
+Josh Chaney Every day here is a different challenge here. Keeps the boredom factor pretty low. Thanks Josh!
Your welcome.
Killer
Looks like a nice transmission, ever work on a Gertrag mt82 ? ... From what I've seen they don't look nearly as nice as these tremecs.
Not yet! They look like a pain from what I've seen. Have a feeling they wouldn't be good for some added hp and abuse...
I have a feeling these are disposable transmissions you need a press in all kinds of things to rebuild them I don't think a Tremec is like that it's a Chinese transmission I have a feeling it's disposable and not rebuildable.
im getting a bad vibration in 6th only 1996 trans am with lt1 and borg warner 6speed shifts fine
I can't picture that issue from the trans. Trans rear crossbeam mount or u joints/driveshaft balance?
2jeffs1 with the driveshaft removed and car in 6th running it vibrates 1st thru 4th no issues 5th has a slight vibration 6rh is worse, pulled trans took to a shop
Quite curious on this one. Will be interesting to see what you find!
when i know ill post it
Thank you for getting back. Will be interesting on that particular issue.
where did you pick up the rebuild kit?
Hi Scott. The parts came from zbag.com/
Awesome thank you
Would you rebuild my T-56 in my 1997 Firebird? Has a LS1 engine. I live in Northern Ohio, 30 miles west of Cleveland in Elyria,Ohio. PLEASE 🙏
How's it going Jeff, I have two T56 transmissions. I have an F-Body LT1 T56 and a C6 ZO6 transmission, My question being what parts would be necessary to take off of the early f-body one to make the ZO6 transmission work. From what I understand I'll need the GTO mainshaft and the LS1 front plate aswell. I think the ZO6 has triple cone synchros and as far as i know I would need those for a higher revving engine since I plan on wrapping out to 8k in the future. Also what parts would be best to upgrade?
And what do you recommend for transmission fluid? I'm considering Nippon ENEOS GL-5 ECO-ATF, i am just not sure if it will cause the synchro blockers to balloon seeing that it's a synthetic ATF fluid but it complies with DEXRON III.
do you offer your rebuild services?
Sorry, no.
Wondering what it would cost to have you do all the work you did on this car, parts and labor. Be real; be sober.
Thumbs up.
+WSmart1 Gotta admit I love this question. You are spot on for your thoughts! They call that - value of repairs exceeds value of vehicle. Many things I buy were rough or junk when they arrived here. I call it 2 ways to look at things. Ok - here's my take. Say you would want to go buy that car in good cond for 10k. After one pays the monthly bills and daily necessities to survive in general how long and how much extra money does one need to make/clear to have that 10 k to spend? And what about interest if one had a loan. Now that car you bought 5 years ago starts leaking oil and starting to need some of this maintenance that I done gets more expensive yet. I guess I look at things in a different way, right or wrong but fun trying! Some of those things I probably could of left alone for a while. I must admit that things do get over killed here. Friends say that too. I do get rough on things periodically and like when there is no worry of breakage or popping the engine. After all the work is done the dependable factor is a good thing too! Thank you for your comment. Neat how you wrote that up!
+2jeffs1 when l do my searching on craigslist l put in needs work, and pick from that list, because most of those have gotten quotes from a shop that were more then the car is worth, but if l do the wrenching l can get double my labor rate , great vid thanks for taking the time,
+mustie1 That is very interesting and helpful. I will be using that. Thank you! On the labor rate here I rarely can charge for actual time invested do to rust/corrosion and surround areas like for an intake (and the inside of them) prep takes more time than the actual work. You only get paid for the job once so no return problems is a good thing. Keeps folks coming back!
Give you a grin - I've never advertised and the shop is not in the phone book. Under my name only. All word of mouth and the nicest people ever to work for. I have a funny feeling that things at your place are quite similar. Thank you for helping out & glad you enjoyed the vid!
+2jeffs1 yep l run the same way, word of mouth,keeps it simple too,
HELP
