Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Tools required:
- OBD-II scanner
- Socket set
- Torque wrench
- Fluid pressure gauge
- Transmission filter kit (if needed)

2. Fluid Inspection and Replacement

Check Fluid Level
- Start the engine and let it warm up.
- With the engine running, check the transmission dipstick. Add fluid if necessary.
Drain Transmission Fluid
- Position a drain pan under the transmission pan.
- Remove the drain plug (if equipped) or the pan bolts using a socket set.
- Allow the old fluid to completely drain.
Replace Transmission Filter
- Remove the transmission pan completely.
- Take out the old filter and replace it with a new one from the filter kit.
Reinstall Transmission Pan
- Clean the mating surfaces and ensure the gasket is properly seated.
- Reinstall the pan and torque the bolts to manufacturer specifications (typically 8-12 ft-lbs).

3. Fluid Replacement

Refill Transmission Fluid
- Using a funnel, pour the recommended transmission fluid (check owner's manual for specifications).
- Start with the specified amount and check the level, adding more as needed.

4. Test Drive and Recheck

Perform Test Drive
- Drive the vehicle to ensure that the engagement issue has been resolved.
Recheck Fluid Level
- After the test drive, recheck the fluid level and add more if necessary.
