Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel, transmission fluid (Mercon LV).
Remove the dipstick and check the fluid level.
If low, add the appropriate transmission fluid until it reaches the correct level.
Inspect the fluid's color; if dark or burnt, a fluid change is necessary.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, transmission fluid pump, pan for fluid collection, new filter and gasket.
Place a drain pan under the transmission pan and remove the pan bolts.
Allow fluid to drain completely, then remove the old filter.
Install the new filter and gasket, ensuring it is aligned correctly.
Reattach the transmission pan and tighten bolts to the specified torque (typically around 10-12 ft-lbs).

4. Reset Transmission Control Module (TCM)

Tools Required: OBD-II scanner.
Connect the OBD-II scanner to the vehicle’s diagnostic port.
Follow the scanner’s instructions to reset the TCM, clearing any stored codes and allowing the system to relearn shift patterns.
Disconnect the scanner after the reset is complete.

5. Test Drive

Reconnect the battery and start the engine.
Shift through all gears to ensure smooth engagement.
Monitor the performance while driving to confirm the issue is resolved.
