C6 help

I took the motor out to have some machine work done. The Trans was running fine before taking out the old motor with all gears and T-Brake from Frank. Installed the motor and transmission but, it did not go into 1st, 2nd, 3rd checked the fluid and linkage I did have reverse. The fluid was good. I did manage to get it into 1st but pressure builds and loses pressure when I give it gas and the RPM rises but the car rolls then stays still . Maybe I am missing something..

did you make sure the convertor was locked in all the way if not you may have mess the pump up

think you didn't have the converter seated and f##k the pump

Yup, pump is junk

If he has reverse the pump is good. Let the engine run long enough where the trans is allowed to warm up a bit see how the FWD engagement is. I'd suspect the inner seal for the FWD clutch piston. My experience with this seal is it can be a long decline that progressively gets worse or all of a sudden one day it no longer wants to seal until warm. I used to drive my 78 F-100 in reverse out of the neighborhood. Then it'd drive o-k forward to get on the main road. Otherwise I'd sit for 5-10 minutes waiting for it to engage FWD.

Best next step?-------drop the pan. If it's full of metal you may have crammed the convertor or have another issue and it needs to come out. If it's clean/normal then drop the V-B and do some air checks with air pressure regulated down to 30-40 psi to check the FWD clutch circuit.
