Sealing Hole in Transmission Tunnel at Handbrake

[240260280z]

Just a reminder that this area is not sealed well.

I used open cell foam that crushes but sealant/caulking/silicone or closed cell foam or rubber matting may do better.

Nice. Was there originally some kind of seal there when new, or was it never sealed at all?

If you remove the handbrake assembly, like I did, you can fab up a 1/4" - 3/16" thick aluminum plate with two holes that line up with the tap holes in the tunnel. I used a large o-ring, think vacuum cleaner drive belt, as the gasket between the tunnel and the aluminum plate.

You can use the o-ring trick even if you leave the handbrake in place.

I used a truck tire innertube to form the gasket and glued an ATV drive shaft boot to it to seal the shaft. I was getting exhaust fumes through that area, thought it was comming from the shifter boot but that was all good, the E brake was the issue, FWIW.
