Solution

1. Preparation

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

2. Check Transmission Fluid

Tools Required: Transmission fluid pump, funnel
Remove the transmission dipstick and check the fluid level and condition.
- If fluid is low, add the specified type of transmission fluid (e.g., Toyota ATF WS).
- If fluid is dirty or burnt, proceed to a fluid change.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, fluid catch pan, new transmission filter, new transmission fluid
Remove the transmission pan by unbolting it and draining the old fluid into a catch pan.
Replace the transmission filter:
- Remove the old filter and install the new one, ensuring it is seated properly.
Reinstall the transmission pan and torque bolts to manufacturer specifications (typically around 8-12 ft-lbs).
Fill the transmission with new fluid through the dipstick tube, following the manufacturer’s recommendations.

4. Inspect and Repair Wiring

Tools Required: Multimeter, electrical connectors
Check for any damaged wiring or corroded connectors leading to the transmission control module.
- Repair or replace any damaged wiring or connectors as necessary.

5. Test Speed Sensors

Tools Required: Multimeter
Disconnect the input and output speed sensors.
Use a multimeter to test for proper voltage and signal output according to manufacturer specifications.
- Replace any malfunctioning sensors.
