Depending on the make and model of your car, you could spend anywhere from $70 to $250 (2010 price) for a transmission fluid change. The higher the car value, the more expensive the repair costs. AAA members may receive a discount for this service. If your car is still under warranty, there will be no out-of-pocket costs. Call around to local repair shops to compare prices.
If you are mechanically knowledgeable, then changing your transmission fluid yourself is much cheaper than paying a professional. If you have the proper equipment necessary—fluid pump, container for the old fluid, ramps, and a ratchet—the the only cost will be that of the transmission fluid and gasket and possibly a filter.
Professionals replace transmission fluid regularly and often offer a warranty on their service. The parts and labor depend on the car value and make, but expect to pay in the low hundreds for the service. Regardless of whether you hire a professional or do it yourself, changing your transmission fluid regularly will save money in the long run. According to CarsDirect.com, change your transmission fluid about every 30,000 miles. Prolonging the life of your transmission prolongs the life of your car.
