Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shock.

2. Check and Replace Transmission Fluid

Tools Required: Funnel, transmission fluid pump, 8mm socket.
Sub-steps:
1. Locate the transmission fluid dipstick or fill port.
2. Remove the dipstick and wipe it clean. Insert it back and check the fluid level.
3. If low, use a funnel to add the recommended transmission fluid (check the owner’s manual for specifications).
4. If the fluid is burnt or contaminated, proceed to drain and replace the fluid.
5. Locate the drain plug, place a drain pan underneath, and remove the plug. Allow fluid to drain completely.
6. Replace the drain plug and torque to manufacturer specifications.
7. Refill with new transmission fluid through the fill port.

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, new transmission filter, gasket.
Sub-steps:
1. Remove the transmission pan by loosening the bolts with a socket.
2. Carefully lower the pan and allow any remaining fluid to drain.
3. Remove the old filter and replace it with a new one, ensuring it is securely fitted.
4. Clean the mating surfaces of the transmission pan and the transmission case.
5. Install a new gasket and reattach the transmission pan, torquing bolts to manufacturer specifications.

4. Inspect Torque Converter

Tools Required: Torque wrench, suitable jack stands.
Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the inspection cover (if applicable) to gain access to the torque converter.
3. Inspect for any signs of wear or leaking fluid around the torque converter seal.
4. If slippage is detected, consider replacing the torque converter.
