Rebuilt a T90 transmission for the CJ3. sorry, didn't have the camera to get pics during the process. trans.jpg (46035 bytes) And here's a transfer case that I'll rebuild for the "new" transmission over the winter. I've already cleaned up the case, and some bolt-on parts. transfer_parts.jpg (60898 bytes)
