I have a 2002 Hyundai Sonata (automatic transmission) that has recently been “jumping” when the car shifts between 2nd and 3rd. This happens only after the engine is “warm”, and does not happen in any other gears or when I downshift. Please advise on what could be the problem. Thanks

Phillip

Has the tranny been serviced? Try getting the fluid drained and filter changed. Only use Hyundai automatic transmission fluid!
