My daughter has a 2002 Saturn SC1 three door with approx 33,000 miles on the car. Intermittently when at an idle if you go to put it in first gear the motor will shake and it will be extremely difficult to put into first. Doesn't matter whether the car is cold or warmed up and doesn't happen all the time. Took the car to the Saturn dealership and they ran their tests on the car and said that it checked out fine. Any thoughts as to what may be going on? Thanks for your reply in advance. Mike
