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.

Un plugged the transmission harness and fluid was inside the fitting. Pulled the old seal out and put a new one in and presto no more leak!

this is the only place i could find this seal reasonably priced, not even GM showed it at all. my order went off with out a hitch and i got tracking directly from ups within a day. this is exactly what i needed to dry up the leak on the back of my 2007.5 lmm Allison.

Simple Install. Saves you from having to replace the harness if the leak is through the terminals!!
