Materials and Tools Required:

Safety Precautions:

* Park the vehicle on a level surface and engage the parking brake. * Allow the engine to cool down completely before starting any work. * Wear gloves and safety glasses to protect yourself from hot fluids and sharp metal edges.

Procedure:

1. Locate the Transmission Seal: The transmission seal is located at the rear of the transmission, where the driveshaft connects to the transmission output shaft. 2. Drain the Transmission Fluid: Place a drain pan under the transmission and loosen the drain plug to drain the transmission fluid. Allow it to drain completely. 3. Disconnect the Driveshaft: Using a socket set, remove the nuts and bolts holding the driveshaft to the transmission. Carefully lower the driveshaft and secure it out of the way. 4. Remove the Old Seal: Using a screwdriver, carefully pry out the old transmission seal from the housing. Clean the housing surface thoroughly to remove any old gasket material or debris. 5. Install the New Seal: Apply a thin layer of transmission fluid to the new seal and insert it into the housing. Tap it in gently using a hammer or a suitable tool. 6. Reinstall the Driveshaft: Lift the driveshaft back into place and reconnect it to the transmission output shaft. Tighten the nuts and bolts securely. 7. Fill the Transmission Fluid: Refill the transmission with the recommended amount and type of transmission fluid. Check the transmission fluid level and add more if necessary. 8. Test Drive and Inspect: Start the engine and let it run for a few minutes to circulate the new transmission fluid. Go for a short test drive and check for any leaks or unusual noises.
