Need to know if anybody has heard of any trany problems as far as when I come to a stop the tranny once in a while kicks me in the a$$. Feels like someone hits me from behind. dealership has no idea. Doesn't feel anything like backlash or u-joints. Almost becoming a safety issue if it gets worse. Anybody have any ideas?

I had this problem when i un installed my banks. For me it was one of the pins in the connections for the computers. The one that the mods patch threw, Was not plugged in. The pins have a habit to push out the back end rather then push into the harness.

Do you 2 foot the brake and the gas pedal?

Be honest now :D

Just a guess here but it could be related to the(over drive) torque converter lock up circuit? And yes I have stayed at a Holiday Inn Express...my$0.02 worth
