Is it hard to rebuild a th400?
-
No. Not hard at all.
Probably the easiest automatic transmission ever.
One of mine survived for a couple of years in a mud truck where the owner never hooked up the fluid cooler........for real.
-
Ok I had to take it out because the output shaft is messed up. I took the valve body off and the output shaft had a lot of play in it to were it shudder so bad it slowed down while going 63
-
How do I get the last bit of gears out of the transmission
-
If you took the valve body off there should be a 12-point headed bolt with a hole through the middle of it that holds the center support in. Take that out and the entire gear train should just slide out.
-
Is ether of the shafts on this move at all
-
There is a big snap ring that holds the rear output shaft into the planetary ring gear. Take that snap ring out and that all comes apart.
-
Is there a way to tell if it's going bad?
-
Visual inspection would be a reliable and cheap method.
If it all looks ok it probably is.
-
It looks ok but when I got it apart I notice some big pieces of metal in it
