Over at jeepgarage someone suggested to unplug battery or remove F60 fuse in order to fix harsh shifting issues. I could really say that my transmission shift rough in lower gears, until I tried the F60 fuse removal for 15min. What a difference! The shifting is now so smooth, it feels like CVT! :D It also feels like the 1st gear engage sooner from a line, the initial delay is gone.
The TCM is supposedly learning your driving style and if you take it easy, the shifting will be smoother.

Update: the TCM must not like my driving style :)
Yesterday I have reset it again and so much better, just so it will get worst over time.
Now I wonder if TCM could be on switched power instead of permanent, that will clean it it up every time.
