6L80 Transmission Cooler Seal(s)

CTX-SLPR · Sep 25, 2024

Howdy,

Not finding an answer so does anyone know the part number for the transmission cooler seal(s) on the side of the case? Need to change my cooler lines and I don’t trust something that comes in individual pieces to come with all of the needed gaskets or to confirm it’s O-rings and a locking plate.

Thanks

Here's the GM TSB on that thermal valve change over, page three has the part number for those seals.

No thermal valve on a 2013 6L80.
