- Multimeter
- Transmission fluid pump
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the engine and transmission to cool before servicing.

2. Change Transmission Fluid

Drain the existing transmission fluid using the transmission fluid pump.
Replace the transmission filter if applicable by removing the transmission pan.
Clean the transmission pan and inspect for metal shavings or debris.
Refill the transmission with the manufacturer's recommended fluid type (check owner’s manual for specifications).
Torque the transmission pan bolts to the specified torque values.

3. Replace Torque Converter Clutch Solenoid

Locate and remove the torque converter clutch solenoid from the transmission (consult repair manual for exact location).
Disconnect the electrical connector and remove the mounting bolts.
Install the new solenoid and connect the electrical connector.
Torque the solenoid mounting bolts to the manufacturer's specifications.

4. Reprogram Transmission Control Module (if applicable)
