I happen to have all the new replacement parts necessary for a failed 6T70 6-speed transmission overhaul, and I would like to get them off my hands at a negotiable price. If that interests you, PM me.
I'm sure it's not easy, but I'm not a mechanic so I wouldn't have attempted it regardless. I don't want to push you into getting in over your head. Cost wise, I'd ship you the parts for a lot less than a remanufactured trans.Is the rebuild process super hard?
