Transmission problem
1980 Chevy Camaro V8 Two Wheel Drive Automatic 186000 miles

Hello
I have a 1980 Camaro Z28 with the TH350 Automatic. I can't seem to get my pan to stop leaking. It didn't start leaking until I put a shift kit in and reinstalled the pan with a new gasket.

I even purchased a new pan (figuring the old one was warped around the bolt holes) and the leak is worse now!

Is there a specific bolt tightening sequence (like with head bolts) that will make the gasket seal correctly?

Also, is there a type of gasket that prevents leaks?

I've been trying to find this info online, but haven't had any luck

thanks for your help!

Hi
Did you use any type of sealant on gasket?

nope, didn't use any sealant. I heard it could break off into the pan and get stuck in the passages of the tranny...

Thanks

That's correct Torque pan bolts to 71-89 inch lbs. use front back side side alternating sequence then torque final in a rotating around pan bolts. Is fluid level correct? is filter paper or pick up screen?
