Comangi Posted February 8, 2015 Posted February 8, 2015 Hey all, so I was curious which 5 speed trans I have. After looking at this thread: http://comancheclub.com/topic/11104-how-to-tell-whether-you-have-an-ax-15-or-a-ba105-5spd-trans/ I decided I must have the BA-105, because my MJ is an '86 with the 2.5L i4. Well i climbed under the jeep and look what I found, does this not look like an AX15? Does that mean someone swapped it? The 3rd pic ^^^^ clearly shows the "midplate" mentioned in the thread. Am I just lucky? Thanks for any and all input/opinions!
Pete M Posted February 8, 2015 Posted February 8, 2015 the ba-10/5 only came behind a 4.0L. as did the AX-15. you have an AX-5. :thumbsup:
Comangi Posted February 8, 2015 Author Posted February 8, 2015 AX5. Ok. So how reliable is that trans? Better than the BA-10? but not as beefy as the AX15?
Crash Posted February 9, 2015 Posted February 9, 2015 AX5. Ok. So how reliable is that trans? Better than the BA-10? but not as beefy as the AX15? From my understanding, this is correct.
Eagle Posted February 9, 2015 Posted February 9, 2015 The AX-5 is not as beefy as the AX-15, but there are those who would say it's better than the BA10/5. Personally, I rate them about equal but AMC/Jeep must have thought the BA10/5 was stronger or they wouldn't have used it when they introduced the 4.0L engine in [model year] 1987.
Incommando Posted February 9, 2015 Posted February 9, 2015 In hear "more reliable" for AX5 rather than stronger. The two often but do not always mean the same thing.
Pete M Posted February 9, 2015 Posted February 9, 2015 the comparison to the ba-10/5 is kinda irrelevant since you can't just swap them. the engine block to bellhousing bolt patterns are different between the 4.0 and 2.5l.
mnkyboy Posted February 9, 2015 Posted February 9, 2015 I abused my AX4 for many years, it was still working fine when I finally pulled it to swap in the AX15. IMO the AX4/AX5 are great light duty transmissions.
randomguy310 Posted February 17, 2015 Posted February 17, 2015 I had a 86 Comanche 2wd long bed 2.5 ax5 street driven truck and broke 4th gear one time...

The BA-10 was represented as a medium duty trans. Barely somehow. And we got it because Renault owned 46% of AMC back then and chose to buy that POS trans from their buddies over at Peugeot.
