I just got my th400 installed and it keeps leaking fluid. It looks like its leaking from the front of the pan. I have a cork gasket on the pan now. I just got a TCI gasket and I must say its a POS. Any suggestions on a good gasket?

Duraprene (spelling) gasket. It looks like thick paper.

do you have a fill tube with an "O" ring or a boot. it may not be the gasket but the fill tube. if it leaks with the engine running it might be the pan gasket. if it leaks over night it's the "O" ring good luck jk

+2 for the durapreme. Make sure that your pan is good and straight. Especially around the bolt holes. Always make sure to torque the pan as well. I normally use 110 in lbs on most pans using this gasket. Works very well for me. If you find that your pan is not straight I have new 400 deep pans in stock. Vince

The tci I just got looks like thick paper. Does that mean its durapreme? I assumed its wasnt better then my cork gasket becasue it was thinner.
