Dude.... you just showed all of UA-cam how to be a true bro. God bless you and America
Wish I would have found and watched this about 20 yrs. ago...
Dude.... you just showed all of UA-cam how to be a true bro. God bless you and America
I swapped out my original transmission for a junkyard transmission a couple years ago and referred to your video. Just now I finished swapping the junkyard transmission out for the rebuilt original transmission and had to refer to your video again. I'm so glad you posted this!
Thanks! I looked everywhere for this explanation and you killed it!
Glad I found you.
Learned more from your video than 3 or 4 others I watched. It might not have been my transmission model, but the set up is the same. Thanks for the info!
My boy just saved me my sanity. My 86 El Camino did not like RPMs. Tighten the cable and now we have an RPM party. THANK YOU!
Great to hear!
Good to know! I'm swapping out a 350 to a 700r4 next week and will make sure the mechanic knows about this. He builds race cars and should know but it never hurts to ask for sure! Thank You!
Looks like you got a good transmission. So far I haven't had to mess with the TV cable on any of my stuff. Good show keep it up
@Jason Boswell yep it seems to be running well! I have to do the lockout wiring next... be sure to subscribe to see that video too! thanks for watching!
Good video, only issue I could think of with the whole “shift at 20mph” is different vehicles have different gear ratios in axles
Thats because this is not the correct way to do this. Different 700r4s will have a different governor spring/weight combination that will yield varying shift points. The cable is there to maintain proper line pressure with proper throttle arc radius measured with a pressure gauge that screws into the side of the transmission. The only way to change shift points is change the springs and weights in the governor assembly.
You should make a video on adjusting that transmission and those governors you’re talking about
@@resistorstudiosgood info okay so where would I find this info your talking about?!? Thank you
@santanaman6783 which info? WOT shifts or setting line pressure?
Great tutorial! Thanks. I appreciate your input. Alot better than any other video on TV adjustment.
Thanks, that's exactly where I'm stuck om my 700r4 from 400 in my 67 Camaro.
Just found your video. Good job on explaining how the TV cable works. It’s backwards from how I would think it works. I’m using a TCI universal cable and the instructions suck.
Thanks brother; I hadn't figured out the fine tune adjustment yet.
U could also tell by how hard or soft the shifts are between gears .. should be firm smooth shifts throughout.. make sure sufficient fluid aswell
Great video..especially the fine adjustment on the tension of that TV cable..that black widow classic .truck is kool AF!...sure wish I never let my '56 small window go...someday...another will cross my path..thanks
Good post, I just purchased edelbrock carburetor and throttle bracket is different got the right one now but I still have to fix adjustment on transmission cable. This is a big help.👍😎
Glad it helped THANKS FOR WATCHING!
Wicked vid - No BS just delivers the good's. Thank you
I learn something new about the transmission I didn't know
THANK YOU FOR THE RELAXED. YET SUPER INFORMATIVE TIPS FOR SETTING SUCH AN IMPORTANT ADJUSTMENT. The BEST to you and YOURS!
Exactly what i needed to know, im replacing a TH180 with a TH 700r
The TV cable mount has a button . Press it to move the cable back and forth.
Very helpfull video.Thank you for this!Keep up the good work!Greetings fron Greece!
I bought a corvette 1984 whit a burned transmission...whit a fresh engine carb swap...will check that cable for sure...
Great video thanks for showing great detail
the tv cable is the most critical adjustment on your car, if it gets loose for too long you will walk soon,this cable controls line pressure and tells the unit how hard to shift,if it breaks you'll have nothing but low gear and reverse and they will harsh,the tv cable on hydraulic units is real touchy,after building automatics for 47 years,pay attention to this man he's trying to warn you.warned
Hi there, just got a 1985 C5 with this issue, prior owner did a carb swap from tpi but apparently didn't properly set up the tv cable/brackets for the 700R and car does fist and hardly engages on 2nd, reverse also works, I'm not driving it to avoid further damage. Is this a sign that the trans is already gone in your experience? Will get correct bracket kit and adjustment on it soon.
@@mattc9875 BEINGS you are smarter than most,stopping the driving may have saved the internals,only way to check is pull the pan,look for any signs of metal dust and clutch material,the intermediate band is a selective pin,C5 vettes already have the good stuff in them,as i stated in my first statement the TV cable is a very sensitive adjustment,once set it'll give years of use,but i adjust them every other year,replace them every 85k miles,they wear the inside of the cable housing and stick and cause wierd shifts,check pan and you'll know the extent of damage if any,good luck
@@strattuner thanks, really appreciated pal, I wish car people around here were half as knowledgeable as you and this guy in the video
@@mattc9875 LOT OF SCHOOL PARD,ALL MY LIFE,SEMINARS AND MANY HOURS OF STUDY AT GM CHRY AND FORD TRAINING CENTERS,YOU ARE WHAT YOU DO,YOU HAVE TO TAKE IT SERIOUSLY
Hello, my '83 C10 is shifting waayyy too early (5-10mph), can this damage my transmission???
Thanks for the video sir, this is exactly what I needed! 👍🏻👍🏻👍🏻
Great video! I have a 85 corvette and the setup for the TV cable has never been clear to me, (not well explained even in the factory service manual).
Thanks again and awesome truck!
Awesome video🙌 very informative! 👍
I inherited my father's 70 Jaguar XKE with an LT1 and had a turbo 400 with a B&M shift kit,
used to bark the tires when you hit second🤗 but then he swap that out and wanted it more streetable as you did and put a 700 R4, but now it shifts as if the tranny is slipping?
I will try and adjust it.. hopefully that is the problem.🤞🤞
Thanks for the great video. 🙌👍🙌
I put a aftermarket throttle body on my 305tpi and noticed it shifting early as heck. Gunna try to tighten this cable up
My trans was late shifting (revving up before shifting from 1 to 2) I heard a new (TPS) Throttle Position Sensor could fix this problem. I almost paid $40 when i saw this video. I went to look at my TV Trans cable and found that it wasn't snapped into place at the Throttle body. IT WAS ONLY OFF BY LESS THAN A 1/4 INCH! And that caused all this bad shifting.
The way u have that done at the end is exactly how my 85 s10 2.8v6 with 4l60 trans shifts and it has over drive too
Goes in over drive 4th at around 40mph or so
@@KnuckleHeadGarage27 My 1990 chevy 1500 with 700r4 also doesnt go into overdrive until 40 mph and if it goes under 40 it drops down to 3rd
@@reece7259 yeah mine does same thing . I kinda hate it cause of high rpm if I have to do 35mph on some roads . I know a ford I had would go into over drive at like 35 or something like that but probably wasn't supposed to idk but I wish mine would kinda go into over drive at 35mph . But then I have to have a 5 speed auto to do that
How about if you're into the throttle, like if you're denting the floor board with your gas pedal, where should it shift then? P.S. I ran mine without the cable hooked up at all for like 3 or 4 months, wouldn't shift unless I let off the gas like a 4speed , but could shift it manually with no problem.
Didn't hurt the trans at all?!
It is a built r4 by Transco out of Florida, guess they do good work cuz it's still going up to a 406 with a little nitrous! I didn't know who did it till I seen a sticker on the trans that says "Transco". 6yrs now, still going strong!
Excellent How to and easy to understand.
1 question are you manually locking the torque converter as well ?
Just in case somebody needs to know... the TCC solenoid just needs 12v you can hook a switch up to manually do so but be aware if it's not going through the 4th gear solenoid in the trans it will stay in lock up when you stop.
Really great video and Nice Truck !!!
Thank you for taking time to make such a detailed video on TV cable position.
Keep up the good work
Comment, Liked, Subscribed!!! Thanks so freaking much for that video!!! Finally explained and Understood!!!!!! Thanks!!!!!!
Sheez, I adjusted my TV cable and got a much clearer picture. Thanks!
Ha ha ...nice ! :)
I love you it's all in the same I been beating my head into a wall messing with timing thanks
Dude you are a fucking genius! This by far the easiest, simple straight forward tutorial.
Thanks for watching!!
best explanation ive found thanks
Glad it helped!
Hey ...Great video my new friend !
*GodSpeed Brother ! Liked/Subscribed !*
Thanks Bud ive only seen valve body kits or electronic conversions $$$$$
Wow haha. This is exactly what I needed. Bought an old 85 c10 that had a new transmission but the TV cable was out of whack so it wouldn’t go into overdrive. So thankfully you made this video
glad it helped! THANKS FOR WATCHING!
How much did you adjust it?? I have no overdrive currently
Great video, wish i found it before i burned up my trans
Thanks for the info. Well done video. My recent "ran when parked" purchase doesn't have third or fourth gear. My TV cable is way loose and has a micky mouse bracket someone made. I'll try adjustment, but I'm guessing it's too late for the trans.
This has got to be the best described video i watched. Im from a th350 to 700r4 and im not a mechanic by any means. This helped..
legend has it Nobody has found one of those barrel nuts. go ask somebody at home depot for one I dare you! 😆 🤣
thanks for the video, I really appreciate the info...easy to understand!
God Bless you , so well explained in plain english . Thank You
Good stuff man!
Thank so much, from Bangkok.,,,,,
Hey guys...could use some advice. Got a 1993 G20 Chevy Sports Van. She's a 5.7 V8 .So this was part of the seller's inheritance. She sat for almost one year and prior to owners death, had no Transmission issues. Her trans fluid was dark. I had all fluids changed today and asked the mechanic what he found in the transmission pan. He said there were a few shavings and the fluid was dark but that was it. He told me he was no Transmission guy but really felt like I did not have a transmission problem. The car acts like it has no reverse at all. I was told by a transmission guy to Rev it up a bit after warming it up. If the front clutch in the transmission is stuck together, I should feel it buck like it wants to go into reverse but it can't. I GOT nothing in reverse period. It drives in Neutral which the mechanics that did the fluid changes said they have never seen. I have a 700R Tranny. Sooooo...do I have a shift solenoid / TV cable problem, some sort of cable that's come undone ? My fear is that this is something less expensive than a transmission rebuild and I don't know enough to know what it is ? What do you guys think ?
If it has forward with the shifter in neutral that sounds like the shift cable is way out of adjustment. Basically what the shift indicator says is reverse is neutral.
Easiest way I can think to test this is get under there and disconnect the shift cable, (with the engine off, block the wheels and set E brake!) Put the trans in reverse (one click back from park) then go put the shifter in reverse, see if the cable matches up to where the shift lever is. Id bet it won't match up, and if you were to start the engine with it like that (I wouldn't) it would suddenly have reverse again. If not you've got a bigger issue to deal with.
Nice. Thanks for upload
Thanks for watching
Can you tell bout the nut you used after cutting the cable
it's just a cable nut I picked up from Ace. your local hardware store should have one. basically just a tube that slips over the cable, then 2 bolts you tighten to keep it in place.
Stay away from 700 r4 is the best thing to do it will never take place of 350 and the 400s
You must love running 4000rpm on the highway or installing super tall highway gears and having no acceleration.
Great tip. No long explanation. Just the facts. Thanks
At time ~ 3:30, is the "tautness" adjustment with the spring and lockknob done with the throttle fully closed? or fully open?
by d looks it seems like an ex sketeboard sport mechanic . good tip thnks
Was up bro. Already subscribed nice job. Next week I’m painting my white walls like on your other vid. Thanks
SWEEEEET!!! thanks for subscribing and watching!! hope the white walls turn out great for you! I've done it several times and have had good results. people are always shocked in disbelief that it's paint and not "actual" whitewalls... thanks again! go RAIDERS!
Much Appreciated
Thank you...i knew this was where the speed transmission gear adjust was....but i didn't know which cable direction loose or tighter to get into 2nd gear quicker....which would be looser for me.
very useful vid cause in my truck when i first got it my dad tightened the tv cable all the way up and i was 10 so power was cool and it would shift out hard asf and then we were cruising hit it and tranny went byebye with the driveshaft
I'm up in Chicago mornings and nights at this time is low 30's anyway my truck when I start it and run it a few mins. I put it in drive and it won't shift till 2000 rpms won't go into second gear till 2000-2500 rpms. I'm having carb issues it needs a rebuild I'm thinking of Edelbrock intake and carb. It's a 83 Chevy c20 350 hd/ 700r4 overdrive
I also just got a new transmission from trans shop. Could the late shifting be the TV cable. I know I'm having carb issues especially the automatic choke. I'll need to rebuild the Rochester 4bbl
After your bulk adjustment, do u need to do a fine tune adjustment? My plastic slider is all the way in, does it need to be all the way out? How would I go about adjusting that part
hey bro i have a 1990 corvette it was stalling in reverse changed the tps and still doing the same thing do i have to ajust the tv cable thanks for your video if you have any idea let me know thanks,
This is a huge help for my son & I and his 94 z28 kick down cable adjustment. Thank you👍
If you put in a transgo shift kit with the manual mode, can you just pull it out and clamp it in full throttle mode?
Great videos your exploration 💯🙌..
I just put 700r4 on my 60 chevy i bin fighting the adjustment 1st to second feels good 2d to 3d ok but im not feeling 4th ???
I have moved n adjusted im stuck almost afraid to drive truck i dont want burn it up
Any suggestions
Excellent ! My cable was way to loose; tightened it up . Thank you
Does your 700 R4 noticeable shift into 4th gear? I definitely feel one two three, but i never notice four? Great video thank you
I want that truck !!!
How many wires are on the plug that go into the transmission of a 700 R4 Pigtail/Socket??????
So I think I may have burnt something up. My cable is loose. I replaced carb. I did see a bit of smoke, but it was in park. This was over a bit of time of me starting it through out winter. Not driving. My car wont shift outta first now. Its has something to do with my trans cable Im sure. Too much slack. Am I describing a burnt out trasnmission? How can I test it its just the cable or if I need to rebuild it completely? 😬
Just bought a 1999 Silverado 4×4,,and tranny keeps going in and out of overdrive.. anybody have any tips? I've already changed filter,fluid and gasket and it still does it. Thanks alot and GREAT video man!🤘🤘
What if it dnt shift after 40 miles? I had a avs2 carburator installed but for sum reason dnt go pass 40 miles naw?
There is a widespread misunderstanding of this cable. Making a used 700r4 transmission a longshot.
My 700r4 doesn't change up to 4th until 50 miles an hour. 1.5 shift kit installed. Have been adjusting cable for days.. any ideas please.
Thank you bud
Bought a cable was too long bought another 1 like 1 came with it done swap nether less never installed one what a pain wish done wright one in first place but hard to adjust s10 blazer had junk 2.8 like your videos motor looks nice 🙂
What bracket would I use for the JEGS stainless steel cable, and a TBI?
Awesome video got my TV cable dialed in on my firebird and she is ripping 🤟
As I was changing my transmission once I had the new tranny bolted to the engine I tried to bolt the flywheel to the torque converter. I tried to turn the crankshaft, but the flywheel wouldn’t turn! It is frustrating and I don’t know why it stopped turning. I had no problem turning it when I took the old tranny out. I need help or any tips or advice you guys can help me with.
A tip, whe you pull (nicely) that steel cable, you'll feel a some kind of (brake) but it's to short, thats the point of tension. Just do it slow and nicely.
After an accident we're my truck completely die, im building a "new" old truck. SALUDOS desde México. I suscribe!
great advice hermano!! muchas gracias!!
Mines make my engine idle high so high when in drive the car just go with no acceleration
Thank you Sir👍😁✌️🙏🏻👌
My tv cable is slipping. Can I put lubricant on it to get a spring to work better.
They do not sell t v cables anymore. They sell rebuild kits that look tedious
My Edelbrock carbed, 5000 lb (ish) conversion van with 1991 700r4 is shifting about 17-18 mph under really light throttle, (maybe 22-23 medium-hard throttle) and shifts 31-32 into 3rd. 42-46 into 4th Is that safe?
If I'm on the gas a bit harder, won't shift into the 4th until I hit 50mph or so
You didn’t tell them the most important adjustment. These cables can cause a lot of damage. Your only adjustment should be cable slider all the way in and open throttle to wide open position then your throttle cable is set. You will hear it click as you open the throttle. This is very important trust me. Once set Leave it alone. This cable controls line pressure. You will burn the clutches quick playing with this bad boy.
I did how exactly you stated on your comment all the way in and open throtle til it clicked... I like how it shifts and everything... I noticed 2nd shift kicks in around 17 and third around 28... Also when gassing it acceleration is actually pretty quick as shifting.... Is that how it supposed to function.... Thanx in advanced
My cable is all the way out lose. Still shifts at 25 mph and firm. 84 305 with Eddy carb
Thank you for sharing your knowledge brudda! Good tip on marking the position as well. I always thought you get the main setting by WOT then basically dial it in as you’ve mentioned.
Great ride!! Take care!!
Perfect video dude! Keep up the good work! -PROJECT HELLPIG
Does the same guidance apply to the 200-4R? I think it does but I thought I'd come straight out and ask. Thanks for posting the part of snugging up the slack cable to begin with in the engine compartment. That was good since everybody else assumes you have a perfectly fitting cable to begin with.
you can always drop the pan and do a visual. a proper adjusted cable should have the plunger all the way in at wot. also make sure your pedal is achieving true wot. have someone hold it down to the floor then manually open the throttle arm. if you can’t move it then you’re good. if you can then you need to check your pedal and throttle linkage/cable
Did you have a problem with your TV cable leaking?I replaced mine because it was leaking and it looks like the new one is leaking.
I know this comment is 3 months old but I had the same problem. What fixed it for me was putting the rubber boot in the transmission first and then sliding the tv cable into the boot. Putting it on the tv cable first ended up crushing it and not sealing correctly.
I have a holly demon carb, with the 700r4 brackets to hold the cable thing in the back, do i also need the holly plate that bolts onto the throttle also??? ;-;
Dude u saved my a**!
I just put a B&M 700r4 in my 1971 C20, not one other UA-cam video- OR written instructions from multiple manufacturers mentioned the spring in line with the tv cable! I appreciate you very much and this video. 🍻
You must have big gonads to hold a cable lock right above those monster venturi's!!! Great video and lots of good info.
I adjusted my cable because it was shifting to hard/delayed and it’s still doing it with the cable loose
Thank you very informative Im getting a 700r but was worried about how to set up cable.. thanks again
Glad it helped
I saw a guy he always works on cars he said the way to adjust the atv cable is open throttle body all the way the atv cable should be Out all the way
Thank you so much for your expertise! Went to carburated on my 5.7l crate engine with edelbrock perfomer dual plane intake and a 1406 carb. It does just what you're talking about with throttle pedal and shif point. I need to put a spring on mine because it shifts at different speeds depending on throttle position. Not wanting to burn up this transmission. Thanks
Thank you. I'm adjusting my cable in a 1990 Suburban and started with the book method of pushing the plastic end all the way in and allowing it to ratchet out at WOT and got mixed results: It now shifts better, but feels like bit too late and it struggles to stay in overdrive at around 60 mph. I've just loosened it about that much that you've shown and will see.
