car sometimes jerks when put into reverse

QUESTION: I have a 1998 Saturn SL2 Sedan with automatic transmission- 48,000 miles. The car sometimes jerks when put into reverse- In the last three weeks or so, it sometimes slips a little going from neutral into first gear, and sometimes when i hit about 50 mph. I've checked the transmission fluid, it's not discolored and the level is fine. What do you suggest I do? Transmission fluid and filter change? Can a transmission be serviced without costing a fortune? I don't know a good mechanic in my area and don't want to get ripped off. could you please advise what steps you think I should take? I already checked transmission fluid level. ANSWER: I'm not sure what you mean by slipping when you go from neutral into first gear. Does it take excessive time to go into gear? If you are telling me that it slips at 50 and the fluid is full and clean then I must tell you that it is probably not going to be fixed by doing a service. I would seek out a good transmission specialist and have him diagnose it. I hate to tell you that even tho the fluid looks full and clean it sounds like an internal transmission problem. Sometimes they can be repaired by just removing the valve body, but prepare for the worst. An overhaul is probably needed.
