The car starts and runes fine in the mornings which have been cool. My drive to work is short so the gearbox doesn't usually heat up a lot. Lately during longer trips the transmission starts to exhibit problems. 1.downshifting harshly during an aggressive stop 2. accelerating away from this sort of downshift is like the gearbox is spinning but not engaged, car moves into gear abruptly and drives as normal 3. The worst seen to date is that the car was in gear on a residential street, warm car, warm day...I could rev the engine, and not really move faster. The car did also shift 1-2..?? Parked car for 45 mintues and drove. Does this sound like a diagnosis can be made quickly? Is this a 0 problem or a 00 kind of problem? Thanks
