Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues during repair.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Using a funnel, add new transmission fluid if low; ensure it meets Toyota specifications (typically, Toyota Type T-IV or WS).
3. Start the engine and let it warm up, then check the fluid level again.

3. Replace Transmission Filter

Sub-steps:
1. Drain the transmission fluid by removing the drain plug.
2. Remove the transmission pan by unscrewing the bolts, taking care to catch any remaining fluid.
3. Replace the old filter with a new one, ensuring a proper seal on the gasket.
4. Reinstall the transmission pan and torque bolts to manufacturer specifications (typically around 7-9 ft-lbs).

4. Adjust Transmission Linkage

Sub-steps:
1. Inspect the transmission linkage for any signs of wear.
2. Adjust the linkage according to manufacturer specifications, ensuring proper alignment with the transmission.

5. Check and Replace Throttle Position Sensor (if necessary)

Sub-steps:
1. Disconnect the harness from the TPS.
2. Remove the TPS from the throttle body.
3. Install the new TPS and reconnect the harness.
4. Adjust the TPS according to manufacturer specifications.
