Merchant Automotive Allison 1000 Pass Through Connector Seal and Body, Duramax | 2001 - 2019

Transmission leaking by wire harness? 

With age the seal can degrade and allow fluid to get into the connection. This can cause erratic transmission operation, possible codes, and even force the transmission to go into "limp" mode.

This is an easy to install fix if fluid is present in your connection.

Comes with the connector seal and body.
