I have tried to duplicate it with different driving styles but nothing happens. When I try to manually shift down to 1st gear I feel a similar "jerk" but I dont think its only happening in that gear when in D. I have not yet had it looked at for that reason but plan too soon. If you get an answer please post it and I will do the same. Also I am in Texas now and the weather is.... Hot and Humid so I dont think it has anything to do with the problems in the earlier posts.
I have not noted the RPM when that happens and I notice no real difference in performance other then that sudden "jerk". Also, there has been no Transmission light that comes on.
Mine now seems sorted after a complete transmission replacement under warranty.
Chyrsler techincian came up but would not talk to me at all, report given to dealer was nothing found but fault most probaly in trans and authorised a replacement.
Still have the "over temp " message and they are trying to say it is nothing just a characteristic of the software "beleive " it is that they do not know what is causing it.
I did check through the tsb's and any relevant ones were flagged up to the dealer for action but nothing resolved
The dealer did say however that the 2008 GC's were flashed to update the software but it cannot not be done for the commander??
which has the same running gear. Revison version not compatible??
Apart from the " temp" message which I still have I also still have the hesitation on applying the accelerator after coasting e.g. like coming off roundabouts etc.
