Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid pump.
Remove the transmission pan using a socket set.
Inspect the transmission fluid for contamination; if it appears burnt or dirty, drain the old fluid completely.
Replace the transmission filter if applicable.
Refill with new transmission fluid as specified in the owner’s manual, using the appropriate type (typically Toyota ATF WS).
Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.

3. Inspect and Replace Transmission Mount

Tools Required: Jack and jack stands, socket set.
Raise the vehicle using a jack and secure it with jack stands.
Locate the transmission mount and inspect for cracks or excessive wear.
Remove the bolts securing the mount to the transmission and the frame.
Replace with a new transmission mount and torque the bolts to specifications.

4. Test Throttle Position Sensor (TPS)

Tools Required: Multimeter.
Locate the TPS on the throttle body.
Disconnect the TPS electrical connector and use a multimeter to test the resistance across the terminals while moving the throttle.
If readings are outside the specified range, replace the TPS.
