Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, transmission fluid, funnel, transmission filter, and gasket kit.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if applicable) or access the fluid fill port.
Remove the dipstick and wipe it clean, then reinsert it to check the fluid level.
If low, add the appropriate transmission fluid as specified in the owner's manual.
Inspect fluid condition: If it appears burnt or contaminated, proceed to drain old fluid.
Drain transmission fluid: Remove the drain plug (if equipped) and allow fluid to completely drain into a suitable container.
Replace the transmission filter: Remove the filter using a socket set and install a new one, ensuring a proper seal with a new gasket.

3. Inspect and Address Leaks

Visually inspect the transmission for leaks around seals and cooler lines.
Tighten any loose fittings or connections.
Replace damaged seals or lines if necessary.

4. Test Drive and Monitor

Reinstall the dipstick or fill plug securely.
Start the engine and allow it to reach operating temperature.
Take the vehicle for a test drive, focusing on acceleration to ensure the issue is resolved.
