Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, fluid catch pan, funnel.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Transmission Fluid Change

Drain the Old Fluid:
- Remove the transmission drain plug using a socket set.
- Allow the old fluid to completely drain into a fluid catch pan.
- Replace the drain plug and torque it to the manufacturer's specifications (typically around 14-20 ft-lbs).
Replace the Transmission Filter (if applicable):
- Remove the transmission pan by unscrewing the bolts with a socket set.
- Carefully detach the pan and replace the filter inside.
- Clean the transmission pan and reattach it with a new gasket.
Refill with New Fluid:
- Using a funnel, pour the manufacturer-recommended transmission fluid into the dipstick tube.
- Check fluid levels according to the dipstick indicators and add fluid as necessary.

3. Electrical Connections Check

Inspect the transmission control module (TCM) wiring and connectors for corrosion or damage.
Clean and reseat any loose or corroded connections.
