Title: Sealer, gasket for trans tunnel
Post by: Donut on October 14, 2008, 05:22:23 pm

I'm starting to put my truck back together and was wondering... What is used for a gasket on the tranny hump in a 4x4? (the bolt on pan)

 When I pulled the old one off it had various colors of silicone, and a blob of what looked like roofing tar.

Butyl tape would probably work the best.

Hadn't thought of that, thanks!

Butyl tape works good. Also the tape they make to run the length of a metal roofing where the sheets over lap each other works real good. It is kinda like butyl but a little bit more like foam two sided tape. I have used both and they both work good.

Blazin,

When butyl tape was mentioned that's the first thing I thought of.  Next trip to Home Depot.
