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?
