Let the dealership look at it homemadewrx is right about the specialty tools. At my dealership we have a huge torque wrench. Also there is alot more with this tranny it even has its own oil pump. We are taking one appart right now at my dealership.So just to be safe let the dealership do it. Also if they decide to warranty or not when the tranny is fixed it does go back to the original warranty. Im not sure how it is if a different shop does the work.
