This might be first grade but below is the list of trannys for Peaches '86 CJ7. I know the list says the 177/178 R for trucks but I have a question.
Peaches tranny ('86 CJ7, 258, 4sp, D-300, D-30/44, 3.31 gears factory) is not aluminum, it is cast iron & I was just sitting here thinking about it & all these web site saying the CJ has the aluminum tranny. Hummm, now the CJ8 I got (in pieces) has the aluminum tranny. Can someone explain this? I was told her Jeep was ordered w/a tow package but ???
Thanks,
Rollbar
P.S. I am also getting some conflicting reports about putting this tranny behind a 360 & people saying it will hold up just fine but then again, I was told it wouldn't. HUmmm, ???
The T-176, T-177, and T-178 are medium duty Ford transmissions manufactured by Tremec in Mexico. They have an aluminum case with the casting number 2604203. This transmissions has a 1 1/8" 10 spline input shaft and a 23 spine output shaft. These transmissions are very similar except for gear ratios. These transmissions use the standar bolt pattern used by Ford transmissions.
Usage:
The T-176 was used in CJs from 1980-1986 and other Jeep trucks from 1980-1987. The T-177 and T-178 were not used in CJs, only in other Jeep trucks.
