Normally, car owners leave it to their mechanic to check the health of their vehicle’s transmission. Considering the transmission is as important as the engine, it’s important for a vehicle owner to check the transmission as well for not only the proper fluid level but to use the fluid to give some indication of a potential problem. It’s time well spent for a transmission can be costly to repair. The most obvious method to determine the level is to use the dipstick. Also check under your vehicle while in the driveway or a parking spot for signs of leaks. Remember that snow plowing and stop-and-start driving shortens the life of transmission fluid. Be alert while driving for fluid odours, popping, or hesitating gears and unusual buzzing or whining noises.
