T4/5 or AX4/5

[mj2stay]

what is the difference between the T4/5 and the AX 4/5. I've got the 2.5 with a 4 speed that's going south and I found a 5 speed that's got a 6 cylinder in front of it. Will they interchange?

Nope.

 

If you're going to swap the engine, the trannies will not swap. the 5spd that is attached to the 6cyl MUST got with the 6cyl only. 2.8 and 2.5 are 60 degree bell housings and the 6cyl is not.

How about we use the displacements for this conversation. :D Since the 4.0 and 2.8 are both 6 cylinder engines (and they do not share transmissions).

AMC used the T-4/T-5 and the AX-4/AX-5 interchangably in the first couple of years of production. The specs call for the AX-4/AX-5, but when they ran low on trannies they pulled T-4s or T-5s from other production lines and used them in the XJ (and '86 MJ, rarely). They will interchange.

 

But ... those trannies were used only with the '84 thru '86 2.8L V6. If the tranny you found is behind a 4.0L in-line 6, then (a) it won't fit your 2.5L (directly); and (B) it's not a T-4/T-5 or an AX-4/AX-5. Those trannies were not used behind the I6.

Everything I have found about the T-4/T-5 shows that the input shaft length and spline count are different than the AX-4/AX-5. Is this true? If so, how did they use them interchangably? Did they use the same input shaft for the two trannies?

Don't have a clue. I assume they used a version with the correct length and spline count on the input shaft. I know for a fact they used the T-5, because my friend in Greece has an '84 XJ 4-banger that was imported to Greece from the U.S. and it has a T-5 transmission in it.
