Gather the necessary tools and parts.

2. Drain and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission drain plug under the vehicle.
2. Place a drain pan underneath the transmission and remove the drain plug to allow old fluid to drain completely.
3. Replace the drain plug and tighten it to the manufacturer’s specified torque (consult the owner’s manual for the exact value).
4. Refill the transmission with the appropriate type of transmission fluid through the dipstick tube or fill port (consult owner’s manual for fluid specifications).

3. Replace Seals and Gaskets

Sub-steps:
1. Remove the transmission pan by loosening the bolts in a crisscross pattern to prevent warping.
2. Clean the mating surfaces of the transmission and the pan thoroughly to remove old gasket material.
3. Replace the old gasket with a new one, ensuring proper alignment.
4. Reinstall the transmission pan and tighten the bolts to the specified torque in a crisscross pattern.

4. Inspect and Repair Transmission Lines

Sub-steps:
1. Inspect the transmission lines for wear, cracks, or loose connections.
2. If leaks are found, replace damaged lines with new ones.
3. Ensure all connections are secure and properly tightened.

5. Final Check

Sub-steps:
1. Start the vehicle and allow it to reach operating temperature.
2. Check the transmission fluid level again and add more fluid if necessary.
3. Inspect under the vehicle for any signs of leaks after the vehicle has been running.
