The HEH-T is specifically a K code transmission. The lack of a VIN does not change that. There are a few service part transmissions out there that would not have had a VIN. There are also a fair number of originals that did not receive a VIN for unknown reasons. I have not personally observed a VIN on a Metucheon transmission as yet. I have seen several original Metucheon Kars that did not have a VIN on either the transmission or the engine. This does not mean that Metucheon Kars did not receive the VIN stamp, only that I have never seen one.
