Q: How to drain and replace transmission fluid and Transmission Filter?
A: At the specified time intervals, the transmission fluid should be drained and replaced. Since the fluid will remain hot long after driving, perform this procedure only after the engine has cooled down completely. Before beginning work, purchase the specified transmission fluid and a new filter. Other tools necessary for this job include jackstands to support the vehicle in a raised position, a drain pan capable of holding at least eight pints, newspapers and clean rags. Raise the vehicle and support it securely on jackstands. To provide adequate clearance, unbolt the universal joint flange of the lower drive-shaft and pull it aside to the right. With a drain pan in place, remove the pan front and side mounting bolts. Loosen the rear bolts approximately four turns. Carefully pry the transmission pan loose with a screwdriver, allowing the fluid to drain. Remove the remaining bolts, pan and gasket. Carefully clean the gasket surface of the transmission to remove all traces of the old gasket and sealant. Drain the fluid from the transmission pan, clean it with solvent and dry it with compressed air. Remove the filter from the mount inside the transmission. Install a new filter and O-ring. Make sure the gasket surface on the transmission pan is clean, then install a new gasket. Put the pan in place against the transmission and, working around the pan, tighten each bolt a little at a time until the torque figure. Install the universal joint flange. Lower the vehicle and add the specified amount of automatic transmission fluid through the filler tube. With the transmission in Park and the parking brake set, run the engine at a fast idle, but don't race it. Move the gear selector through each range and back to Park. Check the fluid level. Check under the vehicle for leaks during the first few trips. Finalize your automatic transmission fluid level check by driving the vehicle to reach normal operating temperature and then filling to the "FULL HOT" position on the dip-stick.
