Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump.
• Ensure the vehicle is on a level surface, and the parking brake is engaged.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Remove the connector by releasing the locking mechanism.
• Inspect for corrosion or damage; clean the connector pins if necessary.
• If damaged, replace the connector with a new one.

4. Test and Replace Transmission Solenoids

• Remove the transmission pan to access solenoids (if needed).
• Disconnect the electrical connectors from the solenoids.
• Use a multimeter to test solenoid resistance; replace if out of specification.
• Reinstall the solenoids, ensuring they are correctly oriented.

5. Reassemble and Reconnect Battery

• Reinstall the transmission pan with a new gasket, torquing bolts to manufacturer specifications (usually around 12 lb-ft).
