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

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Transmission jack
Fluid catch pan
Screwdrivers
Multimeter

2. Remove the Torque Converter

Drain Transmission Fluid:
- Place a fluid catch pan under the transmission.
- Remove the drain plug and allow fluid to drain completely.
Remove Transmission Access Panel:
- Unbolt and remove the transmission access panel to expose the torque converter.
Disconnect Torque Converter:
- Unbolt the torque converter from the flex plate using a socket set (note the torque specifications for reinstallation).
- Carefully slide the torque converter away from the engine.

3. Inspect and Replace Components

Inspect Torque Converter:
- Check for any signs of wear or damage.
- If damaged, replace with a new torque converter.
Inspect Lock-up Solenoid:
- Use a multimeter to test the lock-up solenoid for continuity.
- Replace if faulty.
Replace Transmission Filter:
- Remove the transmission pan and replace the filter and gasket.

4. Reinstallation

Reinstall Torque Converter:
- Slide the new or inspected torque converter back into place, ensuring it is seated correctly.
- Reattach the torque converter to the flex plate and tighten bolts to specifications.
Reinstall Transmission Access Panel:
- Reattach the transmission access panel and ensure all bolts are tightened.

5. Refill Transmission Fluid

Fill the transmission with the manufacturer-recommended fluid type through the dipstick tube.
Start the engine and allow it to reach operating temperature while checking fluid levels.
