I was looking at my transmission today because the guy I bought it from said it was an aftermarket trans. I think it is a T-5 but I could'nt find 13-52 on the drivers side it did say Borg-Warner and 13-52-065-905 on the bottom and 13-52-066-954 on top. The trans. looks brand new. Also the transfer case has C-300 19-15 on it, I guess this is a d300 transfer case? I'm almost finished with my jeep for awhile but I'm on the lookout for a T-15 or a T-18 and a 304 for a nice summer project. Thanks for all your past replies.
