Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch pan.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Check Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick (if applicable) and wipe it clean.
2. Reinsert the dipstick and remove it again to check the fluid level.
3. If low, add the manufacturer-recommended transmission fluid.
4. If the fluid is dark or has a burnt smell, a fluid change is necessary.

3. Perform Transmission Fluid Change

Sub-steps:
1. Raise the vehicle using jack stands.
2. Place a fluid catch pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan.
4. Replace the transmission filter if applicable.
5. Clean the pan and magnet, then reinstall with a new gasket.
6. Refill with new transmission fluid using the recommended type.

4. Inspect and Replace Faulty Components

Sub-steps:
1. Inspect the throttle position sensor for proper function; replace if faulty.
2. Check the wiring and connectors to the transmission control module for any signs of damage.
3. If necessary, replace the transmission control module.

5. Final Assembly and Test

Sub-steps:
1. Lower the vehicle back to the ground.
2. Start the engine and check for leaks around the transmission pan and components.
3. Conduct a test drive to ensure the transmission operates smoothly without slipping.
