Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Transmission Fluid Replacement

Tools Required: Socket set, funnel, drain pan, torque wrench
Remove the transmission pan using a socket set, allowing the old fluid to drain into a drain pan.
Clean the transmission pan thoroughly and replace the filter if applicable.
Reinstall the pan with a new gasket and torque the bolts to the manufacturer’s specification.
Refill the transmission with new fluid through the dipstick tube or service port, using the correct type of transmission fluid as specified in the owner's manual.

3. TCM Inspection and Repair

Tools Required: Multimeter, screwdrivers
Inspect the TCM location and carefully remove it from its mounting.
Use a multimeter to check for voltage output at the connectors while the vehicle is powered on.
If the TCM is faulty, replace it with a new unit and reassemble all connections securely.

4. Electrical Connection Check

Tools Required: Wire brush, dielectric grease
Clean any corroded connectors and wiring leading to the TCM and transmission.
Apply dielectric grease to the connectors to prevent future corrosion.
