DHD LML/L5P Allison Internal Wiring Harness, 2011-2019 6 Speed

If your truck is experiencing erroneous transmission faults and range codes, you may need to replace your internal wiring harness. Allison internal wiring harnesses are notorious for wire degradation and fluid permeation into the pass through connector. This permeation of fluid into the connector often causes changes in resistance and even open circuit component codes. 

This replacement internal harness from DHD has the fit and function of OE with the advantages of the newest wiring and sealing materials.

For an added layer of leak protection and longevity. Add a DHD 100-255 Internal Harness Lock using the option above. This easy to install lock will support the connector body and prevent accidental harness push through during service/installation.
