Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Transmission Fluid Change

Sub-steps:
1. Place a drain pan under the transmission oil pan.
2. Remove the transmission drain plug and allow fluid to fully drain.
3. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 8-10 ft-lbs).
4. Remove the transmission fluid dipstick and pour in new transmission fluid (Toyota Type T-IV) through the dipstick tube.
5. Start the engine and let it run for a few minutes, then check the fluid level with the dipstick and add more fluid if necessary.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission oil pan by unscrewing the bolts (torque specification typically 7-9 ft-lbs).
2. Remove the old filter and replace it with a new one, ensuring the rubber O-ring is properly seated.
3. Clean the oil pan and the magnet inside it to remove any debris.
4. Reinstall the oil pan with a new gasket and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Throttle Position Sensor (if necessary)

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and unscrew the sensor from its mounting.
3. Install the new throttle position sensor and reconnect the electrical connector.
4. Clear any error codes from the PCM using an OBD-II scanner.

5. Check and Replace Transmission Mount (if necessary)

Sub-steps:
1. Lift the vehicle with a jack and secure it with jack stands.
2. Inspect the transmission mount for cracks or excessive wear.
3. If damaged, unbolt the old mount and replace it with a new one, ensuring all bolts are torqued to specifications.
