Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Fluid Change

Drain Transmission Fluid
- Locate the transmission pan and remove the drain plug.
- Allow fluid to fully drain into a suitable container.
Replace Filter
- Remove the transmission pan (use a socket set).
- Replace the transmission filter and clean the mating surfaces.

3. Inspect and Replace Torque Converter

Remove Transmission
- Support the transmission with a jack.
- Disconnect driveshaft (if applicable) and remove bolts securing the transmission to the engine.
- Carefully lower the transmission to access the torque converter.
Remove Torque Converter
- Unbolt the torque converter from the flexplate.
- Slide the torque converter out of the transmission.
Install New Torque Converter
- Lubricate the new torque converter's input shaft with transmission fluid.
- Insert the new torque converter into the transmission, ensuring it seats properly.
- Reattach the converter to the flexplate and torque to manufacturer specifications (usually around 30-40 ft-lbs).

4. Reassemble and Refill

Reattach Transmission
- Lift the transmission back into place.
- Reinstall all bolts and ensure proper torque settings.
Refill Transmission Fluid
- Refill with new transmission fluid per manufacturer specifications (check the owner's manual for type and capacity).

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and let it idle, checking for leaks.
Test drive the vehicle to ensure proper operation of the torque converter.
