700R4 transmission: will not shift into 3rd just slips.

Fri, 03 Mar 2023 19:23:42 -0700

I installed a 700r4 in my 60 chevy. It only shifts 1st to 2nd it slips when it goes to 3rd. does this have any thing to do with the TV cable not being conected?

700R4 transmission: Is the 700R4 interchangeable with the Turbo 350?

Sat, 06 Sep 2025 18:24:28 -0700

Probably I will get nailed for this one, but here goes.

I have a 1986 Chevy K20 Pickup. It originally came with a Turbo-Hydramatic 350 transmission. It has a 700R4 installed now, which is shot. Will I be able to re-install a T350 with no other wiring or tubing modifications? Should I just be safe and find another 700r4 and throw it in?

Off computer topic I know, but hey do I care? There is a big knowledge base out there.

Regards,

Frank

700R4 transmission: doesn't always catch 3rd when shifting from 2nd to third

Fri, 07 Aug 2020 08:44:32 -0700

when my son leave, his truck shifts fine 1st to second, but when it comes time for 3rd it acts like it finds neutral, he lets the rpm drop down and it hooks up to 3rd fine and goes on after that. his fluild is clean and smells alright, any ideal what's up and if it could be an adjustment.

700R4 transmission: Help with setting the 700r4 tv cable.

Sat, 30 Mar 2019 08:25:15 -0700

I have a 1972 Corvette that I put a 700r4 transmission in and have a question. I have been trying to adjust the tv cable as everyone has told me to Push down on the release tab and push the center tab in on the end of the cable, then go to full throttle and it should then set the cable to the correct setting meaning the center tab should click into place. Mine is free and moves easy, its a new cable and its being put on an Edelbrock duel guad carb setup. However it doesn't click out at all, no movement. Does that mean that it's set and doesn't need anything further? Or does it mean that the throttle lever and tv cable end aren't traveling far enough? I have went so far as to pulling on the cable end to see if it will click out and it does.

700R4 transmission: tranny suddenly quit shifting.

Wed, 24 Feb 2021 11:27:31 -0700

I pulled into a parking spot. When I went to back out, the suburban would not shift into reverse. I shifted into drive and that didn't work either. I shifted back into park, and there was a noise like gear teeth slightly connnecting out of synch.

I shifted back into reverse, and shut the motor off...

what would be the most likely problem??

Thanks much....

700R4 transmission: Why won't my 700r4 downshift?

Mon, 13 Nov 2023 03:18:18 -0700

t.v. cable adjusted properly, spool valve works, and governer is fine but when applying throttle car will not downshift. converter will unlock but no downshift. when slowing to a stop trans downshifts though slightly delayed. trans wasn't overheated and has less than 8000 miles.

700R4 transmission: Won't shift into gear.

Thu, 25 Apr 2019 08:57:34 -0700

I installed a rebuilt transmission from a reputable company along with a used (freshen up with new seals) transfercase and new standard torque converter. I put a quart in the torque converter before install, 6qts in the transmission before startup. I ran the engine till warmup checking the fluid in the process. I moved the shifter through all the gears and back. When i went to put it in park sounded like the transmission was rotating because of the grind on the parking pin. My question is the truck does not shift into gear either forward or reverse could it be the transmission or transfer case? Do i need to readjust the TV cable? I double and triple check all connections.

700R4 transmission: High pitch screeching after 20mins running

Tue, 04 Sep 2018 18:30:34 -0700

Hi all, my 200R4 starts a terrible high pitch screeching after 20mins running. Sounds like “fingernails on a blackboard” but in a circular motion. And happens in or out of gear. From an ‘85 Olds. Highish milage but newish oil/filter. Video is on Youtube “700R4 transmission screeching”

700R4 transmission: Why is my 700R4 completely frozen?

Thu, 27 Mar 2025 12:55:58 -0700

After sitting for a month or so, my 700R4 transmission is completely locked up. I start the engine, but when I put it in gear, it slams into gear violently and the engine dies regardless of the RPM. I jacked the rear wheels off the ground and it does the same thing without the wheels even slightly turning. I can rotate the wheels quite easily by hand while on jack stands.

Any thoughts on this greatly appreciated.
