If your experiencing erroneous transmission range errors or your cluster is not displaying the selected gear, there's a chance your NSBU switch or wiring is at fault. These harnesses are exposed to the elements and commonly have corrosion issues. Our USA made repair harnesses allow you to repair the selected wiring without installation of a chassis harness. 

This repair kit is for 1 plug connector NSBU switches (Allison 29541852 ) found on 2001 2002 2003 2004 2004.5 2005 Allison Transmissions. Our OE color matched wires make installation easy. Kit comes with loaded 12way OE connector with 12" wire, OE style crimp connectors, and heat shrink. For best performance, DHD recommends soldering your wire connections.
