Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid dipstick, temperature gauge, socket set, jack and jack stands.
Safety Warnings: Allow the engine to cool before starting work on the transmission. Disconnect the battery if working with any electrical components.

2. Inspect and Replace Transmission Fluid

Check Fluid Condition: Remove the transmission dipstick and check fluid color (should be bright red) and smell (should not be burnt).
Drain Old Fluid: Position a drain pan under the transmission and remove the drain plug to allow old fluid to drain completely.
Replace Filter: If applicable, remove the transmission pan and filter. Replace with a new filter and clean the pan.
Refill with New Fluid: Reinstall the drain plug and refill the transmission with the correct type of fluid as specified in the owner’s manual.

3. Torque Converter Inspection

Remove Transmission Pan: If necessary, remove the transmission pan to access the torque converter.
Inspect Torque Converter for Damage: Check for any visible damage or wear on the torque converter and its mounting points.
Check Stall Speed: If equipped, perform a stall speed test to ensure it matches manufacturer specifications.
Replace Torque Converter (if needed): If the torque converter is damaged, remove it by unbolting it from the flex plate and replace it with a new unit. Ensure proper alignment during installation.

4. Reassemble and Test

Reinstall Transmission Pan: Ensure a new gasket is used and torque the bolts to specification.
Reconnect Battery: If it was disconnected, reconnect the battery.
Test Drive: Take the vehicle for a test drive to ensure proper function of the transmission and torque converter.
