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.

Engine: Starter turns engine over twice and then stops completly

Wed, 13 Aug 2025 00:14:26 -0700

I recently overheated and the car died. Upon trying to restart the car I turn the key and hear a single click. Thinking it was the starter I took the start to autozone to have it tested and they said it passed. I also exchanged my battery just in chase. After putting the starter and the battery back in I try to turn it over again. I will get two, sometimes 1 turn over and then the starter will just stop. the gauge lights will come on and turn off when trying to start then come back on once I stop. There is no check engine light after the initial few seconds its on when you first turn the key and the fuel pump engages. I am wondering if it is possible the engine seized up but it will roll in drive and reverse (automatic) but I wasnt able to get it to turn using the crank pulley and a socket. Not sure how much force I am suppose to use to turn it but it was extremely hard and I was in fear of possibly breaking something so I didnt over due it.

Summary: When I turn the key I will get 1 or 2 very slow cranks from the starter and then nothing at all. No noise no spark.

Upon inspecting the engine I do see gas on the fuel line as well as tips of spark plugs

I can push the car in drive and reverse but I havent been able to turn it using a socket and the crank pulley.

When I try to start it the positive wire on the battery terminal to the starter gets warm. im assuming due to a bad ground which they all looked good or because the starter is pulling to much power because turning the engine is to challenging due to it possibly being “partially” seized… paradoxical

Auto Part: Why doesn't h35 45196k Tecumseh engine have spark?

Mon, 18 May 2020 19:13:06 -0700

I cleaned the magneto on this 3.5 hp Tecumseh horizontal shaft engine. Its pretty old but I would love to get it running. I cleaned the carburetor. It doesn't have an air filter though. The spark plug looks clean. I cleaned out the gas tank, fixed the pull string. I was told it didn't have spark. What should i do now? Thanks

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....

Brakes: Getting two different size dimensions front rotors

Mon, 09 Mar 2020 10:57:38 -0700

Ok I went to VIP to get my front rotors and brakes for my 2016 Chevy Impala ltz limited .Now in there computer going by my exact make and model year so on. They kept bringing out rotors that I jus new were to big and nobody could understand why and they tried different brands of rotors and so on with the same result they were to big at this point me and the employees were clueless to why this was happening . So then we decided to put in my vehicle Vin number instead . And sure enough they went to grab that rotor and it turned out to be a smaller dimension. Does anyone have any idea why this would happen . I Kno sometimes they make mistakes but we went over everything top to bottom together on the computer and everything was correct as far as putting in my vehicle info . But the VIN number clearly did something different to get a different size pulled up when putting in all the correct information on my car was coming up with bigger size . If anyone has any answers to this would be very helpful myself and VIP both was at a loss of words with no explanation.

Thanks very much if you could shed any light on the matter !!!

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.
