Some Background Info: I bought my car from Hertz rentals and since then have put about 50,000 miles on it. I used to take it to the dealer for oil changes and tune ups, but changed to local oil change places because of the dealer's price. My question comes down to... I have 82,000 miles on my car and do not know if my transmission oil has been replaced or flushed... I assume it has been topped off by the dealer maybe 2 years ago. Recently the mechanic I go to recomended that I replace the transimssion fluid, but he said the Dealer had to because of specific tools/fluids. Sorry if the question is unclear, but can anyone give me some insight on how often I should refill the fluid for my type of car, and if I need the fluids filled or flushed?

Basic advice for transmission is to look in your owner's manual or on RepairPal's estimator to see what service interval for GM recommends for changing your transmission fluid. Many technicians recommend being conservative and changing your fluid somewhat sooner than the manufacturer, and this is good advice. Changing your transmission fluid does not require special equipment, and a competent garage should be happy to do it for you. You do not need it "flushed" with a flushing machine, just changed. Transmission fluid needs to be topped off when the level is low. The levels need to be checked at least every 3 or so months.
