Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level.
2. If low, use a fluid pump to add the correct type of transmission fluid as specified in the owner's manual.
3. If the fluid appears burnt or contaminated, proceed to drain and replace the fluid:
  - Locate the transmission drain plug and remove it using a socket.
  - Allow the old fluid to drain completely into a catch pan.
  - Replace the drain plug and torque it to the manufacturer's specifications.
  - Refill with new transmission fluid using the pump until the correct level is reached.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket, carefully lowering the pan and allowing any residual fluid to drain.
2. Remove the old transmission filter and discard it.
3. Clean the pan and magnet to remove any debris.
4. Install the new filter, ensuring it is seated correctly.
5. Reinstall the transmission pan, applying a new gasket as needed and torqueing bolts to the manufacturer's specifications.

4. Reconnect Battery and Test Drive

Reconnect the battery and start the engine.
Test drive the vehicle to ensure the slipping issue is resolved and monitor for any abnormal behavior.
