Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid dipstick, torque wrench, multimeter.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery before beginning any work on electrical systems.

2. Inspect Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it fully.
3. Remove the dipstick again and check the fluid level. It should be between the "Full" and "Add" marks.
4. Inspect the fluid color and smell. If it is dark or burnt, it may need to be replaced.

3. Replace Transmission Fluid and Filter

Sub-steps:
1. Raise the vehicle on jack stands and ensure safety.
2. Place a drain pan under the transmission pan and remove the pan bolts.
3. Allow the old fluid to drain completely.
4. Replace the transmission filter if applicable.
5. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer's specifications.
6. Refill the transmission with the correct type of fluid (refer to the owner's manual).

4. Test Torque Converter Operation

Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the vehicle to warm up and check for any fluid leaks.
3. Perform a stall test by putting the vehicle in gear and pressing the brake pedal, then applying throttle to see if the engine RPM rises significantly (indicating a malfunctioning torque converter).
