    Hey guys, I ain't a tranny dude so I got a serious question.



    I might be able to procure a 42RE behind a 318 out of a '93 Jeep Grand Cherokee for under $100. What is the difference between the 42RE and the 46RE? I know with the 46 vs 47 it is a matter of better parts. Everything else on the outside is the same. Would this be true of the 42...just a really doped down 46RE?



    If that is the case....I could use it as a spare tranny and beef the living hell out of it to make it into a 46 for the Ram or put it into my XJ behind my spare 318!!! :naughty:

    The 42RE is lighter duty than the wimpy 46RE..... :baby:

    At least the the 42 has a better 1st gear ratio.

    Thanks guys! I also asked a tranny friend and he said they would both bolt up, but like you guys said, it is physically smaller. It can't fit the other stuff in it that the 46RE+ have. Though it won't work as a spare for the Ram, I can use it in my XJ project.



    I just hope I can get it before someone else does. :bluecry:

    Yes it will bolt up. They use the 42re behind 4.0L I6's in Jeeps, and behind the 3.9L V6 (318 minus 2 cylinders) in the Dakota.

    Are you sure its a 42RE and not a 44RE. I didn't think they put a 42RE behind the 318, I thought they always used the 44RE :poke:

    I don't know to be honest. It is just a Grand Cherokee with 5.2L and an auto.....



    I was going to go pull it today...but dangit, it snowed. 76* like 4 days ago and now in the 20s with snow. :wall:

    I know this thread is 14 years old but I just recently purchased a ‘99 Ram 1500 4x4 with the 5.9 v8 in it. Unfortunately the transmission started having problems. Naturally, I started to look into replacement costs and the like and so I needed to know which transmission I had. And much to my surprise, I find that my truck has a 42re in it... Notnonly that, but I found that it is the original transmission to the truck through the ID tag on the radiator core support, as well as on the build sheet I ordered from Chrysler. Now everything I’ve read about this generation of trucks says that shouldn’t be possible. And I have yet to find another one with the same set up. I have only been able to find the 42re that bolts up to the 5.9 in Grand Cherokees and Durangos. Why this anomaly occurred is still a mystery. I would like to replace it with a 46re, but I really can’t find any info on whether or not it will be possible without any major modifications, and if so, what I would need to do to accomplish said swap. I just thought I’d put this in here not only to possibly find the answers to my quandary, but also to inform everyone out there that nothing is set in stone concerning what Chrysler used as powertrain combinations in these trucks.
