I just recently bought a 2002 Saturn SL2 with 65k miles and automatic transmission. While test driving it, I changed gears numerous times to see if it slammed into any gears or hesitated. It never did it. I drove the car to work for 2 days (32 miles each way) and now it’s started randomly hesitating before going into reverse. I’ve tried it from Park to Reverse, Neutral to Reverse, Drive to Reverse, with the Emergency Brake up in Park to Reverse and it really does it like 1 out of every 3 or 4 times. I’ve replaced the air filter and windshield wipers because they were disgusting and I planned on doing an oil change and checking the spark plugs/wires this weekend because I don’t know the last time they were done but like most people, I’m getting worried that I might have a transmission problem.
