Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, jack stands, and safety gloves.
Ensure the vehicle is on a level surface and securely raised using jack stands. Disconnect the battery before starting any work.

2. Transmission Fluid Check and Replacement

Remove the transmission dipstick and check the fluid level.
If the fluid is low, add the appropriate type of transmission fluid (refer to the owner's manual).
If the fluid appears dark or has a burnt smell, proceed to drain and replace it.
Locate the transmission drain plug, place a drain pan underneath, and remove the plug.
Allow the old fluid to completely drain out, then replace the drain plug and torque to manufacturer specifications.
Refill with new transmission fluid through the dipstick tube using a funnel.

3. Inspect and Repair Transmission Linkage

Remove any covers if necessary to access the transmission linkage.
Visually inspect the linkage for wear or damage; ensure all components are properly connected.
If any parts are damaged, replace them as needed.
Adjust the linkage as per the service manual specifications.

4. Test Transmission Solenoids

Disconnect the electrical connector from the transmission solenoids.
Use a multimeter to check the resistance of each solenoid; compare readings to specifications in the service manual.
If any solenoid is outside the specified range, replace it.

5. Verify Brake Pedal Switch

Locate the brake pedal switch and inspect for proper operation.
Use a multimeter to test the switch; ensure it opens and closes correctly when the brake pedal is pressed.
Replace the switch if it is faulty.
