97 ZJ Transmission swap

Hi all,

I have a 1997 Grand Cherokee with the 4.0, 42RE transmission.

I bought it knowing that something was wrong with the drivetrain.

My friend and I have diagnosed it as most certainly having a bad transfer case, but also the transmission fluid is burnt and has some silverish in it (metal). I have opted to just swap out the whole kit and kaboodle.

Here's the question:

A friend of mine runs a local salvage yard, and he has a full setup from a 1998 ZJ. However, when he checks his cross reference, it doesn't show that you can use the 42RE from a 1998.

I've done some searching, and I've had a few people tell me that it's direct bolt on no problem, but I've also had another source tell me that the bellhousing might be different, and that the output shaft pilot may be polished.

Will this work?

Thanks for any and all help!
