Overview
The Crown Automotive T90 gasket, part J0936612, is made for the T90 transmission to T18 transfer case connection. It fits Jeep CJ3, CJ5 and CJ6 models and Willys CJ-2, CJ-3, CJ-5 and CJ-6 models, spanning 1946 to 1971.
The gasket seals that one joint, so confirm both the T90 and the T18 are in your Jeep before choosing it. Owners of other CJ models or Wrangler vehicles should check the covered years carefully.

Telling when the joint needs attention
The gasket between a T90 transmission and a T18 transfer case is a flat sealing joint that takes fluid from both units. Leaks at this joint usually show up as oil on the bellhousing or transfer case face, and the gasket should be replaced once it is hardened or torn. A leak may also come from the seals of the T18 itself, so look carefully before blaming the gasket.
Because the gasket sits between two sizable components, the mounting bolts need even tension. Check that the transmission and transfer case are aligned before tightening, and recheck the joint after the first drive. Old gasket material should be scraped off completely, and mating faces must be clean and free of nicks.
