Solution

1. Preparation

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

2. Fluid Change

Tools Required: Socket set, fluid pump, transmission fluid, fluid catch pan.
Remove the transmission pan using a socket wrench, taking care to collect any residual fluid in the catch pan.
Inspect the pan for metal shavings or debris; clean it thoroughly.
Replace the transmission filter if necessary.
Reinstall the pan with a new gasket, torquing the bolts to the manufacturer's specifications.
Refill the transmission with the correct type and amount of fluid using a fluid pump.

3. Inspect and Replace Components

Tools Required: Torque wrench, various sockets, possibly a transmission jack.
If diagnostics indicated worn or damaged components (like solenoids or clutches), remove the affected parts.
Replace damaged components with OEM parts, ensuring proper alignment and installation.
Reassemble any removed components and ensure all connections are secure.

4. Reprogramming (if applicable)

Tools Required: OBD-II scanner with reprogramming capabilities.
If the TCM was replaced or if there were significant changes made, use the scanner to reprogram the TCM according to manufacturer specifications.
