Solution

1. Preparation

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

2. Check and Change Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench, fluid catch pan.
Remove the transmission drain plug using a socket wrench and allow the old fluid to completely drain into a catch pan.
Replace the drain plug and torque it to the manufacturer's specifications (consult the service manual for the exact torque value).
Refill the transmission with new fluid using the transmission fluid pump and funnel, ensuring you use the correct type of fluid as specified in the owner’s manual.

3. Replace Transmission Filter

Tools Required: Socket set, screwdrivers, new transmission filter, new gasket (if applicable).
Remove the transmission pan if applicable, which may require loosening bolts with a socket set.
Carefully detach the old transmission filter from the valve body.
Install the new transmission filter, ensuring it is seated properly.
Reattach the transmission pan with a new gasket if necessary, torquing the bolts to the recommended specifications.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Shift through all the gears while stationary, and then take the vehicle for a test drive to ensure the slipping issue has been resolved.
