Do I have 42RE or 42RH Transmission?

1997 Jeep Gr. Cherokee Limited w/ overdrive.
4.0 L In Line 6-cyl.

I know there's a code, but I don't know how to figure it out. I'm adjusting the trans. bands and there's a difference between the RE and RH for that.

Thanks for your help.

Try emailing Jeep for a build sheet, you'll need to send them your VIN. - they'll give you your tranny info and a whole lot more.

I am going to say 42RE since the only other automatic transmission mated with the 4.0 in a ZJ was the AW4 and you don't have that. I thought the 42RH (or 46RH?) was a V8 transmission

I think you have a 42RE, just because I think they switched from the RH in 95(?).

Arlo, the ZJ V8s have 44RE/RHs (depending on year), and 5.9s have 46REs.

Edit: Just looked at my '97 FSM. You have an RE for sure.

So early 4.0 ZJ's had the 42RH?

Yep. I'm not sure what year they changed, though.

The 93-95 5.2's have the 46RH, the 96-98 5.2's have the 44RE and the 5.9 has the 49RE just to clear that up

New twist to the Post!

OK this is an old post but I found it in my search so I thought it best to bring it up again here.

Did any of these transmissions share the same transfer-case? Say a 46RH or a 42RE share the same case as the AW4?

Meaning that the bolt up on the rear of them are all the same?
