Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid pump, funnel, torque wrench, multimeter.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Engage the parking brake and wear safety glasses.

2. Fluid Change

Lift the vehicle: Use a jack and jack stands to safely elevate the front of the vehicle.
Drain the transmission fluid:
- Locate the transmission fluid pan.
- Remove the drain plug (if equipped) or unbolt the pan to drain the old fluid into a suitable container.
- Clean the drain plug and inspect for metal shavings or debris.
Replace the filter:
- Remove the transmission pan completely and take out the old filter.
- Install the new transmission filter, ensuring it is seated properly.
Reinstall the pan:
- Clean the old gasket material from the pan and transmission surface.
- Place a new gasket on the pan and bolt it back on, tightening to manufacturer specifications.
Refill the transmission fluid:
- Use a funnel to add new, manufacturer-recommended transmission fluid via the dipstick tube.
- Check the fluid level with the engine running and add fluid as necessary.

3. Inspect and Adjust Linkage

Check linkage alignment:
- Inspect the transmission linkage for any signs of wear or misalignment.
- Adjust the linkage if necessary to ensure proper engagement.
Test operation:
- Shift through all gears with the engine running to confirm smooth operation.
