th350 rebuilding questions, endplay...
I am in the tear done phase of my th350 rebuild, and I have a couple questions.
1. The govenor cover is dented, do I need a new one? if so where do I get one?
2. When I removed the 1-2 accumulator cover there was soppused to be a large spring then the piston, thing is I had to pull the cover out of there and found there was NO spring, just the piston?? Whats up here?
3. Checking endplay with the trans hanging from crane, in a near vertical positon. Dial indicator mounted of magnet base on oil pump zeroed, and I push up on the output shaft. The output shaft will move and then stop at 17 thousands, then if I push a little harder it will keep moving and stop for good at 47 thousands. The book says when vertical I should have between 10-45 thousands, which reading is correct???
btw, the trans was working properly as of a month ago.
any help would be great!!!

Fix the dent.
2. When I removed the 1-2 accumulator cover there was soppused to be a large spring then the piston, thing is I had to pull the cover out of there and found there was NO spring, just the piston?? Whats up here? Get a 1-2 accumulator spring from another transmission.

The book says when vertical I should have between 10-45 thousands, which reading is correct??? Do not use the output shaft to check clearance, you have to check the input shaft as far as end play. .015" is a decent clearance. If you are running almost all bearings then you can go down to .005", otherwisw .015" is fine.
Fix the dent.

1. The govenor cover is dented, do I need a new one? if so where do I get one? Fix the dent. The governor needs about .045" - .090" travel before it touches the cover.

Do not use the output shaft to check clearance, you have to check the input shaft as far as end play. .015" is a decent clearance. If you are running almost all bearings, instead of thrust washers, then you can go down to .005", otherwise .015" is fine.
