Transmission is a major component of the vehicle, always forgotten by the car owners. Customers, always neglect to pay attention to transmission thinking it’ll last forever. Please look at this short video created by Automotive ASE Certified Mechanics explaining the consequences of neglecting certain part of your car, especially the transmission. A good repair shop will check your vehicle’s transmission whenever they service your car and they will tell you if the transmission requires services like to drain and refill or full service (i.e. replacing the transmission oil pan gasket, filter, and ATF). It all depends on the type of transmission your car has.
