Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, multimeter, transmission fluid, and cleaning supplies.
• Disconnect the vehicle's battery to ensure safety before working on electrical components.

2. Inspect Transmission Fluid

• Sub-steps:
  • Locate the transmission dipstick or access point.
  • Pull the dipstick, wipe it clean, and reinsert it to check the fluid level.
  • If the fluid is low, add the correct type of transmission fluid as specified in the owner’s manual.
  • If the fluid is dark or contains debris, consider performing a transmission fluid change.

3. Check Wiring and Connectors

• Sub-steps:
  • Visually inspect the wiring harness connected to the transmission control module for any signs of fraying or damage.
  • Disconnect the connectors and clean them with electrical contact cleaner to remove any corrosion.
  • Reconnect and ensure all connections are secure.

4. Inspect and Replace Transmission Control Module (if necessary)

• Sub-steps:
  • If all previous checks are satisfactory, proceed to diagnose the transmission control module.
  • Remove it from its mounting location using a socket set.
  • Inspect the module for any visible damage; if damaged, replace it with a new module.
  • Reinstall the new module and reconnect all wiring and connectors.
