Solution

1. Preparation

Gather all 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 shorts.

2. Check Transmission Fluid

Sub-steps:
- Remove the transmission dipstick.
- Wipe it clean, reinsert it, and then remove it again to check fluid level.
- If low, top off with the manufacturer-recommended transmission fluid (Toyota Type T-IV).
- Inspect fluid color and odor; if dark or burnt, consider a fluid change.

3. Inspect Transmission Linkage

Sub-steps:
- Locate the transmission linkage under the vehicle.
- Check for any loose or damaged components.
- Adjust or replace the linkage as necessary to ensure proper alignment.

4. Check Engine and Transmission Mounts

Sub-steps:
- Visually inspect the engine and transmission mounts for cracks or excessive wear.
- If damaged, support the engine safely and replace the mounts using a socket set.
- Torque the new mounts to the manufacturer's specifications.

5. Test Throttle Position Sensor (TPS)

Sub-steps:
- Locate the TPS on the throttle body.
- Disconnect the electrical connector and test with a multimeter.
- Ensure the resistance changes smoothly as the throttle opens; replace if faulty.

6. Address Vacuum Leaks

Sub-steps:
- Inspect all hoses connected to the intake manifold.
- Use a smoke tester or carburetor cleaner to identify leaks.
- Replace any damaged hoses or gaskets.
