Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, transmission fluid, OBD-II scanner, multimeter
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan.
Allow the fluid to drain completely into the pan.

3. Remove Torque Converter

Disconnect the torque converter from the engine by removing the bolts securing it to the flex plate.
Unbolt the torque converter from the transmission input shaft.
Carefully pull the torque converter out of the transmission.

4. Inspect and Replace

Inspect the torque converter for signs of damage or wear.
If faulty, replace with a new torque converter, ensuring it is compatible with your specific Toyota Camry model.
Fill the new torque converter with transmission fluid before installation.

5. Reinstall Torque Converter

Align the new torque converter with the transmission and flex plate.
Secure the torque converter to the flex plate with the bolts, ensuring they are torqued to the manufacturer's specifications.
Reinstall the transmission pan and secure it with the appropriate torque on the bolts.

6. Refill Transmission Fluid

Refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
Start the engine and let it idle, checking for leaks and verifying proper fluid levels.
