Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts during repairs.

2. Fluid Inspection and Replacement

Tools Required: Transmission fluid pump, fluid catch pan, socket set.
Remove the transmission fluid pan using a socket set. Allow fluid to drain completely.
Inspect the old fluid for debris and burning smell; this indicates possible internal damage.
Replace the transmission filter if applicable.
Reinstall the pan with a new gasket or sealant and torque to manufacturer specifications.

3. TCM Inspection and Repair

Tools Required: Multimeter, wiring diagram.
Reconnect the battery and carefully check the TCM connections for corrosion or loose wires.
Use a multimeter to measure voltage at the TCM connector while the ignition is on; refer to the wiring diagram for specifications.
If the TCM is faulty, replace it with a new unit, ensuring proper programming if required.

4. Solenoid and Sensor Replacement

Tools Required: Socket set, wrench set, patience.
If any transmission solenoids are found to be defective during testing, replace them. Access may require removal of the transmission pan again.
Replace any faulty speed sensors identified in the diagnostics.
