th400 help
Just got done installing a th400 into a buddys truck. It was a fresh rebuild from the tranny shop, We picked it up new convertor and all.
Pulled his old th400 out and installed the new, Filled up the convertor with around 3/4 of a gallon of atf and installed, did not stack the pump or anything. Filled up with I think around 13 quarts total and is where it needs to be on the dipstick. In let it run for about 15min and ran it through all the gears. It feels like it puts a slight load on the motor in reverse and D1, when running and putting it back in park it grinds really bad on the park pawl. Gonna take it to the tranny shop tomorrow evening after I get off work. Just wondering what the hell?

Re: th400 help
This may be a dumb question but do you have the vehicle on jack stands and when youre putting it back into park the driveshaft is still spinning?

Re: th400 help
is the driveshaft even installed?
If it isn't installed, then you are doing the same as popping it in park at 5 MPH or so. |
