mDrive Auto Neutral Introduced by Mack

Mack Trucks is pleased to announce that auto neutral is now available on vehicles equipped with GHG 2017 Engines and the new “F” generation mDrive. This feature is offered on the following Mack mDrive transmissions:

  • mDrive (Standard)
  • mDrive for Severe Duty
  • mDrive with Crawler Gears

A Mack mDrive engine

Auto neutral will put the mDrive transmission into neutral when the parking brake is set. Once the park brake is released, the shifter will need to be placed in either drive (D) or reverse (R) for the transmission to go back into gear. Auto neutral improves jobsite safety for a variety of applications such as mixers where remote throttle is often utilized.

Auto neutral will be available in TSP for order in mid-May. Effective immediately, auto neutral can be activated via the parameter (P1NFD = True) setting in the Premium Tech Tool for trucks already on the ground.

Please contact 1-877-770-7575 or e-mail Function.BodyBuilderSupport@macktrucks.com to assist with programming parameter P1NFD via Premium Tech Tool / PTT.

For more details on Auto Neutral, please review the Mack Body Builder Manual, Section 9.
