I just purchased a 80 cj5 with the renegade package and 258.This Jeep is all original. What I am starting to wonder is, the tranny should be a t-176 right? But I was reading where they used another weaker tranny in some of the cj's. Any help would be greatky appreciated. By the way, I cant find the tranny tag on it.
If I'm not mistaken the other manual would be the SR4, very bad trans due to ball bearings and their resultant failure. The only downside to a 176 is the rather high 1st gear. Your casting numbers on the cases will be T176: C2604xxx; and for the SR4: 13-32-065-9xx or 13-40-065-9xx. I got the casting info from the 4WD Hardware catalog.

Thanks guys for the info. I just checked a Chiltons and a Haynes and all cj5 that year with the 258 and the 4 banger came with the 176. The cj-7 had the sr-4 with the 4 banger and some of the 258's. Thanks again
