Solution

1. Preparation

Gather tools and ensure safety equipment is available.
Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch basin, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before opening the transmission.

2. Fluid Change and Filter Replacement

Raise the vehicle using jack stands and secure it.
Place a fluid catch basin under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan, allowing fluid to drain.
Replace the transmission filter according to the manufacturer's specifications, ensuring the new filter is properly seated.
Clean the pan and magnet thoroughly to remove any debris.
Reinstall the transmission pan, tightening bolts to the manufacturer's torque specifications.
Refill the transmission with the recommended fluid type using a transmission fluid pump, ensuring the correct level is achieved.

3. Transmission Control Module (TCM) Reprogramming

Reconnect the battery.
Use the OBD-II scanner to check for updates or software reprogramming requirements for the TCM.
Follow the manufacturer's instructions to update or reprogram the TCM if necessary.

4. Component Inspection and Replacement

Inspect the transmission cooler lines for leaks; replace any damaged lines.
If slipping persists, consider replacing the transmission or specific internal components such as clutches or solenoids as diagnosed.
