Transmission Prognostics
p4 dm 03.03.015
The transmission prognostics screen is only available for Allison transmissions. It displays information on the transmission health status (oil filter status, oil level, and oil life). If transmission health falls below acceptable limits, a message will pop-up on the driver display.
Note: For a valid oil level measurement, the vehicle must be stopped on a level surface with the transmission in neutral (N).
