Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Fluid Check

Tools Required: Transmission dipstick or fluid level gauge
Remove the dipstick and check the fluid level; add manufacturer-recommended transmission fluid if low.
Inspect the fluid condition; if it appears dirty or smells burnt, proceed to fluid replacement.

3. Replacement of Transmission Fluid and Filter

Tools Required: Socket set, wrench set, fluid pump
Raise the vehicle using jack stands for access to the transmission pan.
Remove the transmission pan bolts and carefully lower the pan to drain the old fluid.
Replace the transmission filter; ensure the old O-ring is removed.
Reinstall the pan with a new gasket, torquing bolts to the manufacturer's specifications.
Fill the transmission with new fluid using a funnel and pump, ensuring the correct type is used.

4. Inspect and Replace TCM or Sensors

Tools Required: Multimeter, OBD-II scanner
If error codes indicate a failing TCM or sensor, disconnect and replace the faulty component.
Use the multimeter to check the wiring and connections for continuity and shorts.

5. Reconnect Battery and Test

Reconnect the battery and clear any existing error codes.
Perform a test drive to ensure proper operation and that the slipping issue is resolved.
