Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Transmission Fluid Change

Tools Required: Socket set, torque wrench, fluid pump, catch pan.
Sub-steps:
1. Place the catch pan under the transmission drain plug.
2. Remove the drain plug and let the fluid drain completely.
3. Replace the drain plug and torque it to the manufacturer’s specifications (usually around 29 lb-ft).
4. Use a fluid pump to refill new transmission fluid through the dipstick tube (use OEM recommended fluid).
5. Check fluid level with the engine running and add fluid as necessary.

3. Inspect and Replace Transmission Filter (if applicable)

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
1. Remove the transmission pan bolts and carefully lower the pan to avoid damaging the gasket.
2. Clean the pan and inspect for metal shavings or debris.
3. Remove the old filter and replace it with a new one.
4. Reinstall the transmission pan with a new gasket, tightening the bolts to the specified torque.

4. Check and Adjust Throttle Position Sensor

Tools Required: Multimeter.
Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the TPS connector.
3. Use a multimeter to measure voltage output while moving the throttle plate.
4. Adjust or replace the TPS if it is out of specifications.
