Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch pan, funnel.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repair.

2. Check and Replace Transmission Fluid

Fluid Level Inspection
- Remove the transmission dipstick and wipe it clean.
- Reinsert and remove it again to check the fluid level.
- If low, add the appropriate type of transmission fluid (check owner's manual for specifications).
Fluid Change
- Place a fluid catch pan under the transmission.
- Remove the transmission pan bolts and carefully lower the pan to drain fluid.
- Replace the transmission filter if applicable (remove old filter, install the new one).
- Clean the pan and replace the gasket if necessary.
- Reinstall the pan and torque bolts to the manufacturer’s specifications (typically around 10-15 ft-lbs).

3. Inspect and Repair Transmission Components

Check for Leaks
- Inspect all seals and gaskets for wear or damage; replace any faulty components.
Transmission Pressure Test
- Use a transmission pressure gauge to check for adequate pressure during operation.
- If pressure is low, further internal inspection is required, including checking the pump and valve body.

4. Reconnect and Test

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature.
Test drive the vehicle to ensure the slipping has been resolved.
