Will a 6 cyl 4 x 4 auto transmission from a Grand Cherokee swap with a 6 cyl 4 x 4 XJ Cherokee auto transmission?

If it is the same year or compatible year and same motor. It should Check the numbers.

No... and you wouldn't want 95% of the Grand Cherokee trannies anyway...

There are millions and millions of AW-4's running around out there, they are not expensive at all to get from a JY.

Here is a link showing the Grand Cherokee transmissions:

The 42RE used in most of the GC 4.0l's is the worst one of the bunch... a really, really bad transmission.

The trans in my uncles GC is the same as my xj that why I thought!

If he has a 93, then he could have gotten an early production year one with the AW-4 or the AX-15. But that's the only year they are the same. I've sold three AW-4's to GC owners to replace the 42RE when it craps out...

DearJimmy

Thanks for all the insight everyone and thanks for the Link to GC transmissions Whowey! I searched all over the internet and could not find any conclusive information. My friend has both a 1994 XJ and a 1994 Grand Cherokee and I wanted to see if his XJ trans would swap for the bad one in his Grand Cherokee. It looks as if he has the 42RE in his now!

The 42re is a junk box of a tranny (I know I have one). Stay with a AW4..

DearJimmy

If his trans is a 42RE (14 bolts) can he use a AW-4? Does the AW-4 have a 14 bolt flange on the transmission?
