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

Transmission leaking by wire harness? This is usually the issue.

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.
