Occasionally when automatically shifting gears (esp. 1st & 2nd) can feel "jerk" on 2001 Pontiac Aztek

Was really noticable in long stop-go traffic. Has 150,000 miles.

Asked by for the 2001 Pontiac Aztek
check the motor monts.
have you serviced it regularly??
could also be a broken accumulator spring.

yes, have always had it serviced per manual. thanks. will have motor monts and accum spring checked. any other ideas?
