Hello,

I was curious if anyone knew the ratios our transmission uses? It it the same as the gas hemi's? I would not think so, but I was told otherwise.-Erick

All 545rfe transmissions use the same gear ratios.
Doesn't matter what engine they are attached to.

Awesome! That is really nice to know that there are many transmissions out there for our fairly rare jeep.

Yup, 545RFE is very common in junkyards from WJs.......

But they do not show interchange, so I wonder what the differences are.....

Someday I might have to dig into the part numbers from the fiches and see what is different between them.

That would be interesting to know if it is possible to obtain a donor from a WK. I wonder why the dodge 1500's swap?(question from a guy who has never swapped one lol)

I think the only diffdrence is in the transfer case mounting.
You will most likey have to still use your KJ transfer case and swap it onto the trans.

I dont know about the WK or WK2, but the WJ uses the same transfer case mounting and the transfer cases are interchangable.

I have seen a number of WJ transmissions in the junkyard and externally cannot tell a different, all the electrical plugs, belhousing, trans mount, and transfer case side appear the same.

I had been assuming the gearing inside was different, but if thats really true that they are the same I should be able to use a common WJ trans to replace mine.

Thanks for the link, thats very good info. With the older transmissions you could not remove the output shaft and bolt up a transfer case.
