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.
This sensor fits the following:
- 2001 - 2005 - Input speed on transmission converter housing and turbine speed on main case
- 2006 - Early 2015 - Turbine speed on main case
