An automatic transmission service is designed to prevent unexpected failure and to keep your transmission functioning optimally. A few things that can lead to an automatic transmission service include towing heavy loads and insufficient levels of transmission fluid. 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 trouble. 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.
