Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch pan, funnel.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts while working.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the manufacturer-recommended transmission fluid through the dipstick tube.
If fluid is burnt or contaminated, proceed to drain and replace:
- Place a fluid catch pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow excess fluid to drain.
- Replace the transmission filter if accessible and replace with a new one.
- Reinstall the transmission pan, torque bolts to manufacturer specifications (typically around 10-12 lb-ft).
- Refill with the correct type and amount of transmission fluid.

3. Inspect and Repair Transmission Components

Remove the TCM from its mounting location.
Inspect the wiring harness and connectors for damage or corrosion.
Test the TCM using a multimeter to verify proper voltage and ground.
If faulty, replace the TCM with a compatible unit and reprogram if necessary.
Reconnect the battery and clear any stored codes in the OBD-II system.
