What kind of transmission do i have? 2003 3.6L

I was going to order a new radiator today and it asked what kind of transmission I had and I have no idea. I know there are two types but I have no idea how to tell them apart. There was a thread with this info i saw a long time ago but of course I cannot find it now. I have a 2003 Jeep Liberty Limited with the 3.6L engine. Anyone know an easy way to find out?

You mean 3.7 V6? No 3.6 ever offered in a KJ.


Look under the hood at the passenger side of the radiator.If you got to lines running directly into the passenger side tank you have the 45RFE trans,if not you have the 42RLE.Being a '03 you could have either trans.

Yes I did mean the 3.7, not sure why I kept thinking it was a 3.7. It has a couple of aluminum lines running into the passenger side tank. Sorry about the quality of the images, ipad doesn't take great pics at night.

Thanks for your help

I can't see the lines in the pic so not able to help you 100%. If the trans lines are running into the radiator then it is the 45RFE.

Another way to tell is to crawl under the Jeep and count the bolts in the transmission pan. If 15 bolts then you have the 45RFE. If there are 13 bolts in the trans pan then you have the 42RLE. I'm guessing you have the 45 since it appears the cooler lines are running into the radiator but count the pan bolts to make sure.

Just call a dealer with the last 8 of the vin. They can get the tranny model. Now depends if they want to be snobby or not
