Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check the fluid level.
2. If fluid is low, add the manufacturer-recommended type (Toyota ATF WS).
3. If fluid is dirty or burnt, proceed to drain and replace it.
  - Use a socket set to remove the transmission pan.
  - Allow old fluid to drain completely into a suitable container.
  - Replace the transmission filter (if applicable) using appropriate tools.
  - Install a new transmission pan gasket.
  - Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Repair Transmission Control Module

Sub-steps:
1. Locate the TCM, usually found near the transmission or under the dashboard.
2. Disconnect the electrical connector and inspect for corrosion or damage.
3. If necessary, replace the TCM with a new unit, ensuring proper programming if required.

4. Test and Adjust Throttle Position Sensor

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector and use a multimeter to check voltage output.
3. If readings are outside manufacturer specifications, replace the TPS.
4. Reconnect the electrical connector and clear any fault codes.
