I have had an ongoing problem with a harsh 2 to 3 upshift. I can put the transmission in learn mode, and it will shift great for about the first 150 miles of city driving, and then the 2 to 3 upshift will get worse and worse, almost be like there is a bind, which gets worse to the point it feels like you are hitting the brakes momentarily when the shift occurs.
I have read every old post I can find here, and while a number of people have stated they have this problem, I am yet to see someone say they fixed something that finally solved it. Please advise if you know what the fix is. Thank you.
PROBLEM SOLVED!
The harsh 2 to 3 shift has been fixed. I replaced the transmission (by myself) with a 545RFE from a 2009 Dodge Ram 5.7L hemi with 44K miles from Ebay. Paid only $480 with shipping. Gone is the bind, clunk, and harshness. I used the Hemi torque converter that came with it, and it really drives alot nicer with much better fluid coupling than the Euro version had. It is actually fun to drive this Jeep again. I might tear down the old unit to see if I can find the problem. I suspect worn clutches, that the TCM could no longer properly compensate for. We may see at some point.
For anyone else having this problem, changing the transmission really is not that hard but it is quite large and heavy, so you will need a proper jack to raise and lower it. I did it on a creeper, using a scissor type transmission jack. You just need a long set of swivel extensions so you can tilt the transmission downward to access the the bell-housing bolts.
Hi Lars! Im thinking about purchasing the same transmission from the same year and vehicle that you got yours from. I found it on Ebay and it has a 3 year warranty and it cost a lot more than yours did ($1900). I just want to know how yours is doing after 3 years of driving it?
Thank You
