95 to 93

Will for transmission from a 95 gc swap straight over to a 93 with no problems. And will I have to change anything else on the 93 to make the transmission work.

They should swap as long as both Jeeps have the same engine and the 93 isn't an early aw4 tranny.

^^THIS^^. 46RH for the V8 and 42RE for the 6 cyl. Yours is 42RE since you have the 6 cyl.

That could mean the transmissions are different. Google both transmissions and then compare the pans and you should easily be able to tell the difference.

I'll bet you have a 93 aw4. Sorry I can't say if it will work or not, I have one too sitting in my garage as a spare and had the same questions about wheather it can even use it in place of the 42re.

I've heard the aw4 is an arguably better trans

Since the other transmission is from a inline 6. And mine is I don't think it should be a problem right?

The aw4 swap would probably be more involved but it is possible. If both are the 42re it will be a direct swap.I believe to swap the aw4 you have to have the bell housing, tranny mounts, and possibly transfer case but not 100% for sure on the t case.

shouldnt need the transfer case. but everything from the other transmission has to be swapped over. i would think the PCM would have to be swapped as well.

sounds like the OP wants to put a 42re into an aw4 jeep though, so lets talk about that.

figure out what tranny he has first.
if its an AW4 you can use any AW4 out of a cherokee too.
if its a 42RE you need to swap a 42re.

how can you tell? check your shifter. a 42RE will read 1,2,D,N,R,P
an AWD will rear 1-2,3,D,N,R,P

also on your transfer case if you have a 42RE it will be an NP 242 and will rear 2wd, 4wd full time, 4wd part time, neutral, 4low
if its an AW4 it will rear 2wd, 4x4 hi, neutral, 4low. this is hte NP 231 transfer case.

the AW4 will have the np 231, the 42re will be the NP242.

to swap an AW4 into a 42re jeep you need all the electronics, PCM, computer, harness, transmission, tranny mount, driveshafts (front and rear)
you basically need a donor jeep to do it.
if you don't do that, then the only way you can run the AW4 is to rewire it yourself and install a shift kit in the tranny so you can manually shift gears otherwise the computers don't read/work with eachother.

long and short of it; it doesn't work. not easily at least.

and yes the Aw4 is a far superior tranny

Not...
I have a 93zj 4.0 with the AW4 automatic trans. It has the same exact shifter bezels as my 95 4.0 with a 42RE, both have the same NP249 transfer case, the aw4 is good trans, never had a problem always firm shifts.

then your shifter bezels are wrong. dude, an AW4 as the 1-2 3, D. the 42RE doesn't.

this is factory spec. your AW4 (if you have one) is not 1,2,D.



take a pic of your tranny pan and the bezel to prove me wrong
