I don't know if this will help but the level will be different depending on the temp.

1. Verify that the vehicle is parked on a level surface.
2. Remove locking pin (1). Remove the plate of the locking pin with a suitable tool and press out the pin remaining in the cap downwards.
3. Remove the cap (2) from the fill tube (3).
4. Actuate the parking brake. Start engine and let it run at idle speed in selector lever position “P”.
5. Shift through the transmission modes several times with the vehicle stationary and the engine idling
6. Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Special Tool 8863A (1) in up to the stop and pull out again, read off oil level, repeat if necessary.
7. Check the transmission oil temperature. Note: The true transmission oil temperature can only be read by a scan tool in REVERSE or any forward gear position.
8. The transmission Special Tool 8863A has indicator marks every 10mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph, determine if the transmission oil level is correct.
9. Add or remove oil as necessary and recheck the oil level.
10. Once the oil level is correct, install a new dipstick tube cap (2) and lock pin (1).
