Transmission clunk
I havent even seen my new/old jeep yet, but want to find out as much as i can about this tran's clunk from 3rd to overdrive so i can fix it asap. Has anybody had this problem.... i know the fluid is burnt and am wondering if a service will fix it. Iv been told it's got something to do with the clutch cog going to fast or to slow (never herd of one before so iv got no idea if thats even a real part). Either way if the tran's is stuffed ill just upgrade. Thank's

Re: Transmission clunk
no...its basically the same tranny as whats in the current wk's with the 4.7 and 5.7...minus 1 gear. Ya know...some of the durango guys are swapping in tcm's from the newer wj grands and making them a 545rfe. I wonder if the jeep guys with the 45rfe...can do the same? The only difference between the two trannies is the tcm's.....

Re: Transmission clunk
That's something ill be interested in if the tran's turn's out to be stuffed.
But i gotta ask what are the tcm's.

Re: Transmission clunk
OK, i cant find anything to say it's a common problem, so i guess that's a good thing. Ill just have to wait for it to turn up, do the service and see what happen's thank's.
