Solution

1. Preparation

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

2. Remove Transmission Pan

Place a drain pan under the transmission to catch fluid.
Remove the bolts securing the transmission pan using a socket set.
Carefully lower the pan and inspect for metal shavings or debris.

3. Inspect Torque Converter

Remove the transmission from the engine by unbolting the bell housing bolts and supporting it with a transmission jack.
Disconnect the torque converter from the flexplate.
Inspect the torque converter for any signs of damage, such as cracks or leaks.

4. Replace Torque Converter (if necessary)

Install the new torque converter by aligning it with the transmission input shaft.
Secure it to the flexplate with the appropriate torque specifications (generally 30-35 ft-lbs, but consult a service manual for exact values).
Reinstall the transmission and transmission pan, ensuring proper torque on all bolts.

5. Refill Transmission Fluid

Use the recommended transmission fluid type (consult the owner’s manual for specifications).
Start the engine and allow it to warm up while checking for leaks.

6. Road Test

Take the vehicle for a test drive to ensure proper operation of the transmission and torque converter.
