    2007 Yukon Denali XL Transmission Failure

    that makes a whole load of sense and no those options were not offered to me at the dealer.

    Powered Tail Gate failed

    Swapped out the motor and that did not do the trick.

    Powered Tail Gate failed

    2007 Yukon Denali XL Transmission Failure

    We might love them but its likely worth 10k max so to spend 5k on a replacement transmission makes little sense

    2007 Yukon Denali XL Transmission Failure

    You don't think a replacement TechM is the right first step. All the feedback to date has been focusing on that and the bad noise is coming from that unit not the transmission itself

    Upon closer inspection to the wiring loom I noticed some rodent damage. Nothing seems to be chewed through but could they still be shorting? Is it possible this level of wire damage could effect the transmission?

    Thanks for sharing this. Does you think if the struts are faliing it would impact the door motor activating?

    Powered Tail Gate failed
