Name That Tranny...

Ok I know that My 87 Yj with the 4.2 has the BA10/5 tranny in it, but I have a 89 4.2lt with a tranny attached to it and also know that they used two different transmissions that year the BA10 and the AX15.

I have seen pic's of the AX15 but it does not look like it. I have a BA10 that has does not look like that either. SOOOOOOO I am stumped.

The Transmission on my BA10 has fill and drain holes on the side of it and this is the reason that I came to the idea that these are not both BA10's.. But the other transmission does not resemble the AX15 at all.Any other trans used that year or might be some other swap other than a AX15 that also has a Internal slave. .. Would their be a plan of attack to figure out what trans this is ????

Thanks For Reading

Cody

I have an 89 with a ba10 and my transmiision drain plug is facing the rear of the jeep right in between the mount and xfer case not on the side like the fill plug. The fill plug is on the passenger side about halfway up the trany. This is a pugeot Ba10 in my 89 with the 4.2l

My trans has two plugs on the side that i believed to be the drain and fill plug. No plug to speak of on the rear. AND the one that came out of the 89 that does not look like a AX15 had NO drain or fill holes on the side

Yeah i have thought about that but the only one I have is crappy... Will roll by my friends house where my motor is and snap a few pic's tomorrow and look some some markings on the trans to further help identify the mystery tranny. Just have exhausted myself with google and my searches on images of ba and ax transmissions trying to figure this out.

Will take stab two at it tomorrow. Till then my only crappy photo of the trans and motor

Can you get a better photo of the tranny itself? Does the case split on an angle or straight up and down?

That looks like a ba10 to me... Based on the shifter, small size, and it looks like it splits on its length.

I concur that it's a BA10/5.

it splits down the middle on how it is put together and i know the BA10 is but The issue is that i have TWO 4.2 motors and TWO transmissions that can not both be BA10's because they have different housings. At least that is what was told me by my local Jeep Shop. The Transmission I have in my Jeep now has the fill and drain holes on the side that both take a square 5/16th bit. But the Transmission that is on the other motor has no drain plugs on the side so that leads me to believe that it is different.

The only other transmission that Max at MOAB said that it is likely to be is the T5

That looks like a ba10/15. This is what i have in my 89. It looks the same to me and i have put all ba10 parts on it(shifter, slave cylinder) and they match up perfect.
pic 1 is pass side from front, fill plug directly below shifter
pic 2 pass side rear, fill plug to left of square tag
pic 3 driver side actually taken thru hole in the crossmember, theres the drain plug hard to miss
pic 4 driver front, transfer case shifter and slave line & bleeder
looks like u need to dig thru some grime to find your fill/drain plugs
those plugs are some metric size i believe, tried grinding 3/8 down to fit but snapped so found a random punch that fit perfectly so got lucky
damn Peugeot im scrappin this thing the 1st chance i get

That looks nothing like a T5 trans. I am certain you have the BA, it is what came in the first half of 89 from the factory. So unless it was swapped for some trans other than those known to fit the late AMC 4.2, its the BA. It is not the T5, AX15, or either of the NV's....

Ok well if it is the BA then I will have to take pictures of the transmission on my jeep now because the outer casing is different than the one in the pictures.
