Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, transmission fluid dipstick, funnel, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the transmission drain plug and allow the fluid to fully drain into a pan.
3. Replace the transmission filter if applicable.
4. Reinstall the drain plug and torque to manufacturer specifications (typically around 8-10 lb-ft).
5. Refill the transmission with new fluid using the correct type as specified in the owner’s manual (likely ATF+4).

3. Replace Torque Converter

Sub-steps:
1. Disconnect the battery and remove the negative terminal.
2. Remove the transmission from the engine by unbolting the transmission bell housing and disconnecting the driveshaft.
3. Unbolt the torque converter from the flex plate and remove it from the transmission.
4. Install the new torque converter, ensuring it is properly seated on the input shaft.
5. Reattach the transmission to the engine, reconnect the driveshaft, and torque bolts to manufacturer specifications.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for fluid leaks.
