Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and safely supported on jack stands if needed.
Disconnect the negative battery cable to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan
Sub-steps:
1. Remove the transmission fluid drain plug and allow fluid to fully drain into the pan.
2. Inspect the drained fluid for metal shavings or burnt smell; replace if necessary.
3. Reinstall the drain plug and torque to the manufacturer's specifications.
4. Fill the transmission with the appropriate type of fluid (Toyota ATF WS) using a transmission fluid pump.
5. Check the fluid level with the dipstick and ensure it is within the recommended range.

3. Inspect and Repair Wiring/Connectors

Tools Required: Multimeter, wire strippers, soldering iron
Sub-steps:
1. Use the multimeter to check for continuity in the wiring harness to the TCM.
2. Repair or replace any damaged wires or connectors.
3. Ensure all connections are secure and free of corrosion.

4. Test and Replace Transmission Solenoids

Tools Required: Multimeter, socket set
Sub-steps:
1. Disconnect the electrical connector from the solenoid.
2. Measure the resistance across the solenoid terminals; compare with specifications in the service manual.
3. Replace solenoids that are out of specification.
4. Reattach any connectors securely.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative battery cable.
2. Use the OBD-II scanner to clear the P0700 code and any other related codes.
3. Perform a test drive to monitor transmission performance.
