Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission fluid pan using a socket set (typically 10mm bolts).
2. Drain the old fluid into a suitable container.
3. Replace the transmission filter; ensure it is the correct part for the 2018-present Camry.
4. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually about 74 in-lbs).
5. Fill the transmission with new fluid (use Toyota WS fluid) through the dipstick tube, ensuring proper level.

3. Torque Converter Inspection

Sub-steps:
1. Remove the transmission from the engine to access the torque converter (consult repair manual for specific removal procedures).
2. Inspect the torque converter for any signs of damage or wear.
3. If necessary, replace the torque converter with a new unit designed for the Camry.
4. Reinstall the transmission, ensuring the torque converter is properly seated.

4. Test Drive

After reassembly, perform a test drive to evaluate the torque converter's performance.
Monitor for any shuddering or abnormal behavior during acceleration and shifting.
