Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan, socket set, torque wrench.
Sub-steps:
1. Remove the transmission drain plug using a socket set and drain the old fluid into a drain pan.
2. Replace the drain plug and torque it to the manufacturer's specifications.
3. Using a funnel, refill the transmission with the recommended fluid type (check owner's manual for specifications).

3. Inspect and Replace the Transmission Filter (if applicable)

Tools Required: Socket set, torque wrench, new transmission filter and gasket.
Sub-steps:
1. Remove the transmission pan by unscrewing the retaining bolts.
2. Carefully detach the pan and clean the surface where the gasket sits.
3. Replace the old filter with a new one, ensuring it is seated correctly.
4. Install a new gasket and reattach the transmission pan, torquing the bolts to the specified value.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored codes, then test drive the vehicle to ensure the repair was effective.
