Solution

1. Preparation

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

2. Inspect Transmission Fluid

Tools Required: Transmission dipstick (if applicable), funnel
Remove the transmission dipstick (if equipped) or access the transmission fluid fill plug.
Check the fluid level; it should be between the minimum and maximum marks.
Assess fluid condition; it should be a bright red color and free of burnt smell.

3. Perform a Stall Test

Tools Required: Tachometer
Start the engine and allow it to idle.
With your foot on the brake, shift into Drive and gradually accelerate the engine to around 2,500 RPM.
Observe the tachometer; if the RPM significantly increases without the vehicle moving, the torque converter may be faulty.

4. Check for Leaks

Inspect around the torque converter and transmission for signs of fluid leakage.
Look for any fluid pooling or staining on the ground or components.

5. Reassemble

Reinstall the transmission dipstick or fill plug securely.
Reconnect the battery.
