2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, floor jack, transmission pan gasket, torque wrench.
Remove the transmission drain plug or pan to drain the old fluid into a suitable container.
Inspect the old fluid for burnt smell or metal shavings, indicating internal wear.
Replace the fluid filter if applicable, ensuring the new filter is properly seated.
Reinstall the drain plug or transmission pan with a new gasket.
Fill the transmission with new OEM-approved transmission fluid through the fill tube until it reaches the proper level.

3. Inspect and Repair Transmission Components

Tools Required: Socket set, screwdrivers, torque wrench.
Inspect the transmission for any damaged components, such as solenoids or bands.
Replace any faulty solenoids or internal components as necessary, following the manufacturer's specifications.
Reassemble any removed components and ensure all bolts are torqued to specification.

4. Reprogram or Update TCM

Tools Required: OBD-II scanner with programming capability.
Using the OBD-II scanner, check for available updates for the TCM.
