Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Elevate the vehicle and secure it on jack stands.

2. Check Transmission Fluid

• Remove the transmission dipstick and check fluid level.
• If the fluid is low, top it up with the manufacturer's recommended transmission fluid.
• If the fluid is discolored or smells burnt, consider a fluid change.

3. Inspect Wiring and Connectors

• Visually inspect the wiring harness and connectors to the TCM for any signs of wear, fraying, or corrosion.
• Clean any corroded connections with electrical contact cleaner.
• Repair or replace damaged wires or connectors as needed.

4. Test the Transmission Control Module (TCM)

• Use a multimeter to check the electrical signals sent to and from the TCM.
• If the TCM is found to be faulty, remove and replace it:
  • Unscrew and disconnect the TCM from its mounting location.
  • Install the new TCM and reconnect the wiring harness.

5. Inspect Transmission Solenoids

• Remove the transmission pan to access the solenoids.
• Disconnect the electrical connectors from the solenoids and perform a resistance test.
• Replace any solenoids that do not meet the manufacturer's specifications.

6. Reassemble and Refill

• Reinstall the transmission pan with a new gasket if necessary.
• Refill the transmission with the correct type and amount of fluid.
• Reconnect the negative battery terminal.
