727 torqueflite trans pan
 

i can,t seem to seal my trans pan. pan does not seem damaged. Ive used cork and rubber gaskets, silicon and dry. Ive torqued it from 12 to 16 ft lbs. Any suggestions?

Tom I have to ask, are you using an X pattern to torque the pan ? Have you put a straight edge across the pan in various places ? I would try about 20 lbs also.
Oh welcome to the Forum.

welcome to the forum
like polara said, go opposite when you torque
one side, then another, etc.

My not be the pan. The dipstick tube is right above the pan and if the "O" ring is bad or leaking it will run to the pan rail and drip all around the pan and look like the pan is leaking. Check that before you go too much further.

Welcome. You might also want to check where the housing and tail shaft housing meet for a leak.

This is a time when you should have started a new thread but yes a stock pan and filter should fix the issue…
