The automatic transaxle fluid and filter should be changed, the magnet cleaned, and the bands adjusted at the recommended intervals. Begin by raising the vehicle and securely supporting it on jackstands. Place a container under the transaxle oil pan, loosen the pan bolts, and completely remove those across the rear of the pan. Tap the corner of the pan with a soft-face hammer to break the seal and allow the fluid to drain into the container, while the remaining bolts prevent the pan from falling. After draining, remove the remaining bolts and lower the pan. Next, remove the filter screws and detach the filter, which may require a Torx bit. Adjust the bands before proceeding with the fluid change. Install the new gasket and filter, ensuring the gasket is in place before attaching the filter, and tighten the screws. Carefully remove all traces of old gasket sealant from the oil pan and transaxle body without damaging the sealing surfaces. Clean the magnet in the pan with a clean, lint-free cloth; for 1984 models, remove the differential cover to access and clean the magnet. Apply a 1/8-inch bead of RTV-type sealant to the oil pan gasket surface, position it on the transaxle, and install the bolts, tightening them to the specified torque in a criss-cross pattern, working up to the final torque in three or four steps. For 1984 models, reinstall the magnet in the differential cover, apply sealant around the contact surface, and follow the same installation procedure. Lower the vehicle and add four quarts of the specified fluid to the transaxle. Start the engine and let it idle for at least one minute, moving the shift lever through each position and ending in Park or Neutral, while checking for fluid leakage around the oil pan and differential cover. Add more fluid until the level is 1/8-inch below the Add mark on the dipstick, then drive the vehicle until the fluid is hot and recheck the level. Ensure the dipstick is seated completely to prevent dirt from entering the transaxle.
