Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean, reinsert it, and remove it again to check fluid level.
3. If the fluid is low or dirty, drain the transmission fluid using a drain pan.
4. Replace with new transmission fluid as per manufacturer specifications (typically Toyota ATF WS).
5. Recheck fluid level and add as necessary.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Raise the vehicle securely using jack stands.
2. Locate the transmission mounts and visually inspect them for cracks or excessive wear.
3. If damaged, remove the bolts securing the mounts to the transmission and the chassis.
4. Install new mounts and torque bolts to the specified setting (typically around 50 ft-lbs).

4. Test and Adjust Throttle Position Sensor

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and use a multimeter to measure the sensor output.
3. Adjust or replace the TPS if it is out of specification (typically 0.5-1.0 volts at idle).
4. Reconnect the sensor and clear any error codes.
