Random upshift and occasional down shift??
 

Hello!

I'm new to this thread, but have had a srt couple Xfire for a year, and I've been expierencing this problem lately, and I have no idea what it could be?!? I'll be coasting at 60mph and the car will randomly just kick forward, not really accelerating but just enough for me to actually move in my seat. Same for decelerating sometimes, but not as much as accelerating. Automatic, Has high mileage, 126k no accident etc, clean. Can anyone help me find this out?? 😫

Most likely low fluid level caused by leaking transmission connector.
Possibly in more severe cases it could be the conductor plate inside the transmission.
Have you even changed the fluid ? At 126K if you have not, then you are overdue.
