Thanks for the reply. The problem is this gasket is not available anywhere else. I only see it in the picture for Marlins tacoma t-case adapter kit. It is the gasket that goes between the adapter and the 1998 auto trans. I am doing a 3.4L motor swap on my 1990 4runner and originally used RTV/Ultra Grey to seal it. But then needed to pull it to check something before final install, and it took 4+ hours to get it off and damn near damaged my adapter. So I feel having even a few of those gaskets would help. The dealer doesn't even show them.
