Auveco 74444 GM Transmission Connector Harness – 3 Prong For TH250C, TH350C, 2004R, 700R4, TH125C

This is a brand new, never-used GM transmission case connector harness, still in its original packaging.

It’s a direct fit for a bunch of popular GM automatics including the TH250C, TH350C, 2004R, 700R4, and TH125C.

Made by Auveco, this 3-prong harness matches OEM part numbers like 12300205, 74444, and 17199.

It’s a vintage reproduction piece manufactured in Taiwan—so not a universal jobber, but specifically designed for these models.

If you’re rebuilding or repairing an older GM trans, this is the plug you need.
