Okay, I'm totally clueless about these things. My g/f's car ('99 Galant 4g64/auto) is having a weird issue where the trans feels like it's "catching" when stopped and in "D". Occasionally when idling, you feel a momentary kick of power come through the drivetrain. It's not enough to move the car when you're on the brakes. What could this be?
A few observations: The problem just started recently. A year or so back she had the transmission "flushed". Also, the dealer recently performed a recall that replaced the trans cooler rubber hoses. Lastly, the car was involved in a minor passenger's-side accident that required me to replace the strut and spindle. It's possible the inner workings of the trans took a hit through the axle.
Ideas/next steps?
Thanks!
