42RE vs 46RE????

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

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. Blue Cry

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. Bang Head
