Checking transmission fluid levels is important for keeping all internal gears and components clean and lubricated. Grinding noises and leaking will alert you to potential problems early. If you notice a burnt smell emanating from your vehicle’s transmission, there may be a problem with your transmission’s ability to retain fluid. A lack of routine maintenance can contribute to automatic transmission problems. Replacing a transmission can be expensive, so staying on top of automatic transmission repairs and basic maintenance is important for maximizing the life of your transmission.
