Solution

1. Preparation

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

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back and check the fluid level; add the correct type of ATF (Automatic Transmission Fluid) if low.
3. If the fluid appears burnt or dirty, proceed to drain and replace the fluid.
Tools Required: Transmission fluid pump, socket set, drain pan
Safety Warnings: Use gloves and safety glasses when handling transmission fluid.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts.
2. Carefully lower the pan and allow fluid to drain into the pan.
3. Remove the old transmission filter and install the new one.
4. Clean the transmission pan and replace the gasket before reinstalling the pan.
Tools Required: Socket set, torque wrench, gasket scraper
Safety Warnings: Ensure the vehicle is securely lifted and supported if working underneath.

4. Inspect and Replace Transmission Mount

Sub-steps:
1. Visually inspect the transmission mount for cracks or deterioration.
2. Remove the bolts securing the mount and replace it with a new mount.
3. Tighten the bolts to the manufacturer's specifications.
Tools Required: Socket set, torque wrench
Safety Warnings: Ensure the vehicle is properly supported when working under the vehicle.

5. Throttle Position Sensor Adjustment or Replacement

Sub-steps:
1. Locate the throttle position sensor and disconnect the electrical connector.
2. Use a multimeter to test the sensor for proper voltage and resistance.
3. If faulty, remove the sensor and replace it with a new one, ensuring correct alignment.
Tools Required: Multimeter, socket set
Safety Warnings: Disconnect the battery before working on electrical components.
