Hello all,

I have another problem to figure out and need your help. This jeep is quite entertaining... After recent transmission oil/filters change I have got a new problem of quite rough shifting from 2nd to 3rd gear when the jeep is cold. It does this just a couple of times untill crd warms up and then drives normal and smooth till I stop and shut it off. But after a 5 min stop (jeep still warm) it would rough shift again once and then drives perfect. What could this be? Do I need a Quick Learn procedure to follow? Can I do it myself and how?
BTW: I have GDE TCM and ECO tune and fluid level is good and true. Disconnecting battery does not correct the problem as well. Hope this nothing major. Any suggestions please? Thank you all in anticipation.

My bet is on the tranny fluid... It sounds like to me that you didn't use the specified Tranny Fluid.

Very important to use the right OEM ATF4 fluid and that the filter is the right one.

You would lose your bet racetracer - I used ATF+4 and right filters. I was very careful with this. But thank you anyway.
