Transmission has me pulling my hair out !!!
TH350 was not pulling in any gear. I took it out and replaced it with a th350 out of a corvette that is supposed to be fairly new. The guy did an LS swap so I bought his th350.
I put the trans in my truck . Checked it cold and it didn't show any fluid on the stick. I put a quart in it because I figured it needed at least that to fill all the lines ect. I cranked it and it let it get warm. Nothing showed on the stick. I put another quart in and checked it . It was to the add a Pt mark. I put a pint in and put it in reverse. It pulled great. Put it in "D" and it would not pull. Put it in 2nd and would not pull. Put it in 1st and it pulls great. I'm a body and paint man of 26 years and when it comes to mechanicing I know enough to know when to call someone else. But I know nothing about a transmission except how to take one out and put one in. Whats the problem ? Is it trash ? Do I need to have a come to Jesus with the guy ? |

Re: Transmission has me pulling my hair out !!!
Just curious did you put fluid in the torque converter? Thats my first thought, not a transmission guy either though.

Re: Transmission has me pulling my hair out !!!
I took the trans off the engine. Loaded it up , took it home and put it in. Never took the converter off. I didn't want to have to replace the seal.

Re: Transmission has me pulling my hair out !!!
add a few more quarts of fluid as these things take a lot of fluid to work like 8-12 quarts from empty

Re: Transmission has me pulling my hair out !!!
All I can add is that if my TH350 is 1/2 quart low, it doesn't want to engage either forward or reverse, especially if it's been sitting awhile.
Whether you have the selector in D, 2, or 1, it should try to start in 1st gear. Not sure how much you need to add, but I bet it's just low on fluid. Hope so, anyway...

Re: Transmission has me pulling my hair out !!!
I checked the vacuum advance , its hooked up and pulling good vacuum.
I put another quart in and its in the "ok" area on the stick but still wouldn't pull in Drive or 2nd. It tries to pull in "D" and 2nd but just cant hardly do it and you can hear a slight whistle/humming sound or turning sound when its in "D" and 2nd. |

Re: Transmission has me pulling my hair out !!!
Check the vacuum hose on the transmission that goes to your intake. Mine came off once and it wouldn't shift. Also if it was sitting awhile the fluid in the torque converter might of drained back into the tranny case. Keep the truck running, put it in neutral, and keep checking it. I'm not a transmission mechanic but I've had 5 vehicles with th350s and I've had to do this with all of them at some point. If it goes into any gear them you are pumping fluid. Check the vacuum first tho. It's on the passenger side of the tail shaft, should be a short hose connected to a long piece of metal tubing going up to your intake behind the carb

Re: Transmission has me pulling my hair out !!!
Came from a Corvette?
Symptoms sound like it has a "manual valve body". Common drag race item. It is in whatever gear you select no matter what. Congratulations, you get to buy a regular valve body and install it

Re: Transmission has me pulling my hair out !!!
I say drop it on the ground , go to your local tranny supply shop (like a place called Trans star) or summit and get a full rebuild kit for around 200 bones (give or Take) and a frosty beverage and do a complete overhaul, once you see how the thing works inside they are not too complicated, at all...
you can find all the how to instructions on line you do need a couple special tools, like a spring compressor for the pistons assemblies, but most tranny shops might let use theirs or help you with what you need.

Re: Transmission has me pulling my hair out !!!
Yes, and when abused, can strip out the lugs inside the case. It's junk at that point.

Re: Transmission has me pulling my hair out !!!
>>Lol... I've put 5 quarts in it already.<<
What does that matter? You check the oil level hot, and RUNNING. When it's close, run it though all gears (engine still running) and recheck for full. I see guys that are used to driving jap crap, buy these old '60s vehicles and think they should check trans oil with the engine off.

Re: Transmission has me pulling my hair out !!!
Everything I've read on the TH350 says they take up to 10 quarts (from a bone dry condition). The amount varies depending on the torque convertor, cooler, etc. But, as noted above, keep adding a quart at a time. Start the engine after each addition and run it through the gears (pausing about 5 seconds in each gear) with the brakes on while parked. Then, check the cold level on the dipstick with the engine running and trans in park. You have to do this to properly fill the torque convertor. If things aren't engaging after 8 to 9 quarts, you may have a more serious problem.
If this is successful, drive it until the trans fluid is hot and adjust the level. Last edited by FirstOwner69; 08-10-2015 at 12:51 PM. |

Re: Transmission has me pulling my hair out !!!
did you at least drop the pan and change the filter before you installed it? residue and/ or other things in the pan will tell you the condition of the tranny
