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 negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: 10mm socket, transmission fluid pump, funnel.
• Remove the transmission fluid dipstick and check fluid level.
• If low, add the recommended type of transmission fluid (Toyota ATF WS).
• If the fluid is dirty or smells burnt, drain and replace it.
  • Locate the drain plug, remove it, and let old fluid drain completely.
  • Reinstall the drain plug and refill with new transmission fluid through the dipstick tube.

3. Inspect and Repair Wiring/Connectors

• Tools Required: Multimeter, wire brush, dielectric grease.
• Visually inspect the TCM wiring harness and connectors for damage.
• Use a multimeter to test for continuity and shorts in the wires.
• Clean any corroded connectors with a wire brush and apply dielectric grease before reconnecting.

4. Test and Replace Transmission Solenoids

• Tools Required: Torque wrench, socket set.
• Locate the transmission solenoids, usually found on the valve body.
• Remove the transmission pan and filter to access the solenoids.
• Disconnect the solenoid connectors and measure their resistance using a multimeter.
• If any solenoid is out of specification, replace it with a new one, reinstall the pan and refill the transmission fluid as necessary.

5. Reprogram or Replace TCM

• Tools Required: OBD-II scanner with programming capabilities.
• If the TCM is faulty, it may need to be reprogrammed or replaced.
• If replacing, ensure the new TCM matches the vehicle specifications.
• Use an OBD-II scanner to program the new TCM if required, following the manufacturer's instructions.
