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 negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set.
• Sub-steps:
  1. Remove the transmission fluid dipstick and inspect the fluid. Look for contaminants or burnt smell.
  2. If fluid is low or dirty, use a transmission fluid pump to drain the old fluid.
  3. Refill the transmission with the appropriate type of ATF (Toyota WS ATF) through the dipstick tube using a funnel.
  4. Start the engine and allow it to reach operating temperature, then check the fluid level again and top off as necessary.

3. Inspect and Repair TCM Connections

• Tools Required: Multimeter, dielectric grease.
• Sub-steps:
  1. Locate the TCM, typically found under the dashboard or near the transmission.
  2. Disconnect the TCM connector and inspect for corrosion or damage.
  3. Use a multimeter to test the continuity of the TCM harness wires.
  4. Apply dielectric grease to clean connectors and reconnect the TCM.

4. Replace Faulty Components

• Tools Required: Socket set, wrench set, torque wrench.
• Sub-steps:
  1. If any wiring is damaged, cut and splice in new wiring, ensuring proper insulation.
  2. If the TCM is found to be faulty after testing, remove it by unbolting from its housing and disconnecting electrical connectors.
  3. Install the new TCM in reverse order, ensuring all connectors are secure and torqued to specifications.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code and any related codes stored in the system.
