1. Fluid Check and Replacement: The transmission fluid is vital for lubricating the transmission's internal components and allowing them to move smoothly. During a transmission service, the fluid level is checked, and if necessary, the old fluid is drained and replaced with new fluid as recommended by the vehicle manufacturer.
2. Filter Replacement: The transmission filter helps remove contaminants and debris from the fluid. Replacing the filter during transmission service ensures that the fluid remains clean and free of particles that could cause damage to the transmission.
3. Gasket and Seal Inspection: The mechanic will inspect the gaskets and seals around the transmission for any signs of leaks or damage. If necessary, these components may be replaced to prevent fluid loss or contamination.
4. Linkage and Cable Inspection: The transmission service may include inspecting the linkage and cables connected to the transmission, ensuring that they are in proper condition and functioning correctly.
5. Computer Diagnostics: Some vehicles have electronic transmission control systems. The mechanic may connect a diagnostic tool to the vehicle's computer to check for any stored fault codes or abnormalities related to the transmission.
6. Road Test: After completing the transmission service, the mechanic may take the vehicle for a road test to assess the transmission's performance and ensure that it is shifting smoothly and responding properly.
Transmission service intervals can vary depending on the vehicle make and model, as well as driving habits and conditions. Refer to your vehicle's owner's manual for the recommended maintenance schedule. Having regular transmission service performed can extend the life of the transmission and prevent potential problems or breakdowns.
