Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, transmission fluid pump, funnel, shop towels.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and disconnect the battery to ensure safety.

2. Check and Change Transmission Fluid

Locate the transmission dipstick and remove it to check the fluid level.
- If low, add the recommended transmission fluid for the Camry (typically Toyota ATF WS).
If the fluid is dark, burnt, or dirty, proceed to replace the fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket wrench.
- Carefully lower the pan and allow the old fluid to drain completely.
Replace the transmission filter:
- Remove the old filter and replace it with a new one, ensuring any O-rings are properly seated.
Clean the transmission pan and magnet.
Reinstall the pan with a new gasket and torque to manufacturer specifications (typically around 8-10 ft-lbs).

3. Inspect Transmission Mounts

Visually inspect the transmission mounts for cracks or excessive wear.
If damaged, replace with new mounts:
- Support the transmission with a jack and remove the bolts securing the mounts.
- Install new mounts and torque bolts to specification.

4. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check for leaks or unusual noises.
Take the car for a test drive to evaluate the transmission performance.
