Ok second actuator came I ordered a 55567050 and paid for it, waited for it to arrive, picked it up today got home opened it up and inside the box is a 12992408...hmmmm looks very different so I take a close look at the box and see the 55567050 sticker has been placed over top of the 12992408 sticker. This is the old part if I am not mistaken the one that leaked oil into the electrical connection ? Nothin gonna surprise me now ! GM Canada told me they ARE covered under powertrain warranty..they gave me a free oil change since I repaired it myself and paid for the sensor out of pocket....I am down with that, 1 for GM.
