Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick; remove it and wipe it clean.
2. Reinsert the dipstick and pull it out again to check the fluid level.
3. If low, add the recommended transmission fluid (consult owner’s manual for specifications).
4. If fluid is dark or burnt-smelling, drain and replace the fluid.
Tools Required: Transmission fluid, funnel, drain pan.

3. Inspect and Replace Transmission Mount

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission mount and visually inspect it for cracks or wear.
3. If damaged, remove the bolts securing the mount and replace it with a new one.
4. Torque the bolts to the manufacturer's specifications.
Tools Required: Socket set, torque wrench.

4. Test Throttle Position Sensor (TPS)

Sub-steps:
1. Locate the TPS, usually mounted on the throttle body.
2. Disconnect the electrical connector from the TPS.
3. Use a multimeter to test the sensor's resistance values while moving the throttle.
4. If out of range, replace the TPS.
Tools Required: Multimeter, screwdriver.

5. Repair Vacuum Leaks

Sub-steps:
1. Inspect all vacuum lines connected to the intake manifold.
2. Replace any cracked or disconnected hoses.
3. Use a smoke test if necessary to identify leaks.
Tools Required: Smoke machine (optional), hose clamps.
