GM Allison Transmission Speed Sensor | 2015 - 2019

The Allison Transmission Speed Sensor changed in mid 2015. If you own a 2015, use the diagram in the image gallery above to match the connector to the correct sensor. 
 

A failing speed senor on your Allison transmission can give erratic readings causing shifting concerns, dtc codes, and other issues.
