Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid pump, multimeter, drain pan, and funnel.
Safety Warning: Ensure the vehicle is on a flat surface and the engine is cool before starting work.

2. Fluid Change

Step 1: Locate the transmission fluid dipstick and remove it.
Step 2: Use the drain pan to catch old fluid by removing the transmission pan bolts and lowering the pan.
Step 3: Remove the old filter and replace it with a new one, ensuring it is seated correctly.
Step 4: Clean the transmission pan and magnet, then reattach the pan using a new gasket.
Step 5: Refill the transmission with the manufacturer-recommended fluid using the funnel until the correct level is reached.

3. Solenoid Inspection and Replacement

Step 1: Disconnect the battery to avoid electrical shorts.
Step 2: Remove the transmission pan again if necessary to access the solenoids.
Step 3: Disconnect the wiring harness from the solenoids and remove them.
Step 4: Replace with new solenoids and reconnect the wiring harness.
Step 5: Reinstall the transmission pan and refill fluid as described previously.

4. Final Checks

Step 1: Reconnect the battery and turn on the ignition without starting the engine to check for any warning lights.
Step 2: Start the engine and allow it to reach operating temperature, checking for leaks.
Step 3: Conduct a test drive to ensure the slipping issue is resolved.
