Learn how to diagnose and fix P0741 torque converter clutch issues in Tesla Model S Plaid. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the ignition is off.
• Gather tools and parts needed for the repair.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Torque Converter Clutch Solenoid

1. Locate the Solenoid:
   • Remove the transmission access panel if necessary to reach the torque converter clutch solenoid.
   • Identify the solenoid based on the vehicle’s service manual.
2. Remove Electrical Connector:
   • Carefully detach the electrical connector from the solenoid.
   • Inspect the connector for corrosion or damage.
3. Remove the Solenoid:
   • Use a socket set to remove the bolts securing the solenoid in place.
   • Carefully pull the solenoid out of the transmission.
4. Install New Solenoid:
   • Lubricate the O-ring of the new solenoid with transmission fluid.
   • Insert the new solenoid into the transmission and secure it with bolts to the specified torque value (check service manual for exact torque specs).
5. Reconnect Electrical Connector:
   • Attach the electrical connector to the new solenoid.

3. Check Transmission Fluid

1. Inspect Fluid Level:
   • With the vehicle running, check the transmission fluid level using the dipstick.
   • If low, add the appropriate transmission fluid as specified in the vehicle's owner manual.
2. Inspect Fluid Condition:
   • Replace transmission fluid if it is discolored or has a burnt smell. Follow the manufacturer’s guidelines for fluid type and replacement procedure.

4. Reconnect Battery and Clear Codes

• Reconnect the negative terminal of the battery.
• Use the OBD-II scanner to clear the P0741 code and any other stored codes.

5. Test Drive

• Take the vehicle for a test drive to ensure that the P0741 code does not return, and monitor for proper transmission performance.
