Best I can tell from parts catalogs:

'93: 242 Not Available

'94 - 42RE or 44 RE
'95 - 42RE or 44 RE
'96 - 42RE or 44 RE

'97 - 42RE only
'98 - 42RE only

Am I missing anything?

44RH in the 5.2 and 5.9

Ah right, they switched from the 44RH to the 44RE in '96 right?

So only change to what I have above would be switching 44RE to 44RH for '94 and '95?

What are you trying to do?

Nothing, just curious. I like my 242, and like my 42RE at least well enough that I probably wouldn't pay much to change it.

Contrary to popular belief, the 42re is a good transmission if maintained with regular fluid and filter changes and not abused. Don't stop a roll by shifting to the opposite direction. Use the jeep's brakes first!

Oh ya, I've got no major complaints. I don't know the history of mine for sure, but I would guess it's gone without a rebuild for the last 260k miles or so.

And I might abuse it in other ways, but I don't think I could bring myself to shift while going the wrong direction... Is that a common thing?

44RH was never used behind the 5.2 in the ZJ. 46RH on the other hand was used from -93 to -95.

Okay, what do I know about the V8 models? All I know is most of the driveline won't interchange with the 4.0 because everything is larger and stronger. They tell me the steering linkage will swap, but IDK for sure. So far, I've owned 3 jeeps with the 4.0, two with the 42re and now one with the AW4.

Sometimes people get impatient when doing K-turns and shift to forward while the jeep is still rolling backwards. That tends to wipe clutch material off the plates and can cause snap rings to fail, especially on the forward clutch that retains that 800 lb spring in the overdrive section.

That's just basic for any transmission. Some may tolerate that abuse better than others, but it's always abuse; it's always stupid.

I can't agree more, but it is something many people do without thinking. Some people also think manually downshifting hurts the transmission, but done with caution actually helps keep the clutches clean by wiping imbedded particles off them. I never liked automatic transmissions, but then I got a wife!

Heh. I downshift regularly. My wife thinks I'm crazy.

Hmmm. She's not alone in that opinion!

It sure saves brakes on long downgrades.

It does indeed. My regular commute route takes me over the Blue Ridge Mountains along a road that is 40 MPH, and does a lot of twisty-turning and ups and downs. In the XJ, if I drop it down to 3rd, it's perfect. I keep the speed up on the uphills, the speed down on the downhills, my trans isn't thrashing all the time, and my mileage is better. Then the north end is a steep drop for about a half mile, I drop into 2nd, and I need to brake only 3 times. If I run in 4th, it's on the brake the whole time.

I get similar results in my WJ, but not quite as good. I have ot brake a bit more, but still, downshifted works a lot better than not.

Yes, the 4.0 has a history of burning exhaust valves when trying to pull too much torque at around 1500 rpm whereas if kept around 2000, pulls nicely. Driving in my area is like driving over corrugated cardboard! It's constantly up and down unless you're in the glacial melt plain north of Syracuse going toward Lake Ontario. One of the reasons my WJ 4.0 lasted so long is because for the 6 years I've owned it, the converter lock-up hasn't worked and the O/D lockout is a simple pushbutton. When the converter locks up, it runs 1500 rpm at 55 mph. The slightest uphill puts a load on it.
