dropping my tranny pan this weekend. picked up the gasket kit at Napa - it is a thin rubber gasket. I think the oems are a thicker cork/rubber material. anyone use these thin rubber ones with success? they seem a little cheap to me.

 

I've never seen a cork/rubber gasket. I've seen just rubber, or just cork though...not like a hybrid though. Rubber is always better than cork though because the cork ones are weak and cheap and will crack if you tighten your pan bolts too tight. Some gaskets are reusable as well so you may not even have to replace it depending on what gasket is on there right now

 

Cork also dries and cracks, no good.

 

did the pan drop yesterday. the OEM gasket is a paper composite type. I replaced with the rubber Napa gasket - no leaks yet. I think the Napa gasket by itself is only $3 (vs. $24 for the OEM). i got the filter kit for $16 that included the filter screen - however I didn't put it on b/c I couldn't get the old one off without taking off the valve body -- WAY to big a job for me.
