4. Refill Transmission Fluid:
   • Use the manufacturer-recommended transmission fluid and fill through the dipstick tube or designated fill port until the proper level is reached.

3. Repair or Replace TCM

1. Inspect TCM Connections:
   • Ensure all connectors are clean and secure; repair any damaged wiring.
