One of the most common problems with the Allison transmission is failure of the Neutral Start Back Up switch. Replace it with this Genuine Allison part.

Some of the symptoms of failure include but are not limited to:

  • No start condition

  • Gear shift indicator on dash not following properly

  • Trans stuck in limp mode or fail safe

  • DTC's set indicating pressure switch codes

  • This switch easily installs with just common hand tools.
