can i substitute a 42RE for a 44RE in a 1996 jeep Grand Cherokee?

You might try the Grand Cherokee section....Until somebody more in the know comes along, I'm pretty much clueless, but maybe, might want to use your speed sensor?

No, the bellhousing is different between the two. The 42re was used with the 4.0, the 44re was used with the 5.2. The bolt patterns and starter locations are different.

I can't see the transmission code on my transmission. Is there any other way I can tell which transmission I have? My neutral safety switch just went out and there are 2 different ones for this year and model.

For a 98 XJ, with a 4.0L and automatic, it will be an AW4. But the tag wont read "AW4". The tag will read 40-43LE for 2wd, or 40-30LE for 4wd. Both use the same NSS shown.
