Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Fluid pump, wrench set, transmission fluid.
Remove the transmission drain plug and drain the old fluid into a suitable container.
Replace the drain plug and tighten it to manufacturer's torque specifications.
Using a fluid pump, fill the transmission with new fluid until it reaches the proper level according to the manufacturer’s guidelines.

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, torque wrench, new transmission filter and gasket.
Remove the transmission pan bolts and carefully lower the pan.
Clean the pan and inspect for metal shavings or debris.
Replace the old filter with a new one and reassemble the pan using a new gasket.
Torque the pan bolts to the specified value.

4. Test Transmission Operation

Reconnect the battery and start the engine.
Allow the vehicle to idle and check for leaks around the transmission and fluid lines.
Shift through the gears to ensure smooth operation and that the slipping issue is resolved.
