2001-2019 Duramax Speed Sensor Connector Kit (10402)

Fits

Replace your old, brittle factory connector terminal with this durable replacement. It comes with a pair of 22-gauge butt connector terminals and is designed to fix erratic signals and frustrations caused by damaged connectors and wiring.

This connector is perfect for repairing damage to the transfer case speed sensor connector on 2001-early-2007 Silverado and Sierra trucks, as well as the 2001-2019 Allison transmission speed sensor connectors. Over time, these locations can develop cracks and wear out. In 2-wheel drive trucks, the Allison transmission typically has 2 or 3-speed sensors, while 4-wheel drive trucks have 1 or 2 in the transmission and 1 in the transfer case. This part will also fit the 3-speed sensors on 2-wheel drive Medium Duty Allison 2000 transmissions from 2001-2019.

• The number of speed sensors and connectors required depends on the make, model and options of the vehicle, consult the service manual to determine exactly how many speed sensors are present in your particular application.
