The bump between first and second, is not were near as dramatic as when you have the car running and put it into drive and get the usual bump on any auto transmission. Just being paranoid.. How much does a service cost for an auto transmission? Anyone know?
Hard shift between 1 and 2 could be shift solenoid or your tps is out of adjustment, before you go spending $$$ on a service try a nulon auto transmission treatment to try and soften the seals to ease the shift.
