Following a precise sequence prevents false readings and protects the driveline. This procedure is aligned with factory recommendations for the 2006 Grand Cherokee.
- Start with the vehicle on level ground and the transmission in PARK.
- Run the engine until it reaches normal operating temperature, around 175 to 220°F.
- Briefly cycle the gear selector through all positions, ending again in PARK.
- With the engine idling, remove the transmission dipstick, wipe clean, reinsert fully, then remove again to check level.
- Add only the recommended fluid type if needed, avoiding overfilling.
