Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission drain plug and place a drain pan underneath.
3. Remove the drain plug and allow the old fluid to fully drain.
4. Replace the drain plug with a new washer and torque to manufacturer specifications (usually around 29 lb-ft).
5. Remove the transmission fluid dipstick and add new transmission fluid (Toyota WS fluid recommended) using a funnel until it reaches the "Full" mark on the dipstick.

3. Replace Transmission Filter

Sub-steps:
1. Locate the transmission pan and remove the bolts using a socket set.
2. Carefully lower the transmission pan; clean the mating surfaces of the pan and transmission.
3. Replace the old filter with a new one, ensuring the filter is properly seated.
4. Reinstall the transmission pan with a new gasket, torquing the bolts to manufacturer specifications (usually around 7 lb-ft).

4. Adjust Transmission Linkage

Sub-steps:
1. Inspect the transmission linkage for any bends or damage.
2. Adjust the linkage according to the service manual specifications to ensure proper engagement.
3. Test the shifter movement to ensure smooth operation.
