Solution

1. Preparation

• Gather necessary tools and parts for the repair.
• Disconnect the battery to prevent electrical shorts.
• Raise the vehicle using a jack and secure it with jack stands.

2. Check Transmission Fluid

• Tools Required: Transmission fluid dipstick, funnel, transmission fluid (as specified in the owner’s manual).
• Remove the dipstick and check the fluid level; add fluid if low.
• Inspect fluid color and smell; if burnt or contaminated, proceed to fluid change.

3. Change Transmission Fluid (if necessary)

• Tools Required: Socket set, drain pan, new transmission filter, new transmission fluid.
• Place a drain pan under the transmission pan and remove the pan bolts.
• Allow old fluid to drain completely, then remove the old filter.
• Install the new filter and reattach the transmission pan, ensuring all bolts are torqued to manufacturer specifications.
• Refill the transmission with new fluid through the dipstick tube.

4. Inspect and Repair Wiring

• Tools Required: Multimeter, wire connectors, electrical tape.
• Visually inspect wiring harnesses for fraying or damage.
• Use a multimeter to test continuity in the wiring; repair or replace damaged sections as needed.

5. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, OBD-II scanner.
• Locate the TCM, typically found near the transmission or under the dashboard.
• Disconnect the electrical connectors and remove the TCM.
• Install the new TCM and reconnect all connectors.
• Clear the error codes using the OBD-II scanner and retest operation.
