And I thought I was the only one with this problem. I've been experiencing the shift problem for a couple of months now, but I have to remove a few mods before the dealer will look at it and haven?t got around to it yet (mainly putting the OEM air filter back in). From the sound of the above posts I?m glad I paid for the 10 year/100,000 mile warranty (86,000 on the car right now).
I noticed the problem first when driving on the expressway. I hit a small grade and the O/D light started flashing. When I got of the expressway the ATX was shifting rough. Turned the car off and started back up, the O/D light stopped flashing but the car still shifted rough. Later I removed my Superchip, which only improved the rough shifting slightly. Since then I?ve noticed the following symptoms; slams into gears while shifting manually (shifting from park to reverse or reverse to drive for example), shifts rough when auto shifting (gets worse as the car gets warmed up), the O/D light only flashes after driving long distances and only after going up a hill or getting heavy into the throttle (never happens on my daily commute), and I haven?t noticed my car running hotter than normal.
I?ll keep you posted.
-edit-
I forgot to mention that my CE light came on just after I cleaned my throttle body which happened to be about week before the ATX started acting up. The CE light is still on.
