    Shifter Cable Adjustment

    Looking into my shifter issue (2007 Yukon Denali 147k miles) and found this thread. I had the transmission replaced a year ago, then a few months later had the shifter replaced because it would not go into trailer or shift manual. It did go to M though. This was all done at the dealer. Now...

    Whipple 2.3L Supercharger Installation on 2007 Yukon XL Denali (6.2L L92 Motor)

    Yeah, I had to buy my car back after it got slammed by a drunk kid on a Saturday morning while parked in front of my house. The insurance company totaled it, nothing but sheet metal damage and broken taillight. So, I had to pay $600 for the insurance company to do nothing, after paying my...

    GM 6L80 Transmission Information Thread

    Got it back from the dealer today after having the manual/trailer switch assembly replaced. Will pull the trailer around tomorrow to verify that it's working correctly. If so, it's boat shopping time!

    Yukon headlight switch question.

    does yours stay at the off position when you put it there? Mine springs back to "AUTO". So, it's always on AUTO unless and until I turn the dial to off. I'd prefer it to be on off until I select otherwise, as I can do in my Pacifica. Sorry about the old thread, thought I would check before...

    12v outlets always on

    Same thing for me. powered usb FM/Bluetooth adapter, charger for my flashlight, powered phone cradle all stay on unless I pull them from the outlets. I don't use the truck very often so it's not a big deal, but I'd like them switched by the ignition. I'll be ordering the fuse taps as...

    GM 6L80 Transmission Information Thread

    O'Reilly scan says "p0700 TCM Requested MIL Illlumination". Also just drove it in trailer mode, more than 5 times it would not shift up getting to almost 5k RPM at 55mph after slowing for 30mph corners. Have to lift to get it to shift. Didn't do it when going from a stop. VERY frustrating!

    GM 6L80 Transmission Information Thread

    I guess it's time to get a scan tool. I have Dodge, Chrysler and Acura vehicles as well. What's a good one for a beginner that will work with these different makes?

    GM 6L80 Transmission Information Thread

    To clarify the history - the shifting problems began around the first of this year, and the manual shift mode stopped working at the same time. The two shops I took it to prior to the dealer both said it need a transmission rebuild or replace. They did not say that the manual shift mode, which...

    GM 6L80 Transmission Information Thread

    I hope this is the correct place to ask this question, if not I apologize. I just had my 6l80 transmission replaced on my 2007 Yukon Denali with 147K miles by the chevy dealer Bill Roberts Bolivar MO, for $5600. When I got it back yesterday, I tried the manual shift mode and it does not do...

    2007 GMC YUKON CRUISE CONTROL STOPPED WORKING

    I have the same issue. The amber light is still on at the steering wheel but the green light doesn't come on and the unit does not engage. Replaced the brake switch, no change. What would you look for next? I don't have a scan tool but I'm interested in buying one if it looks like it will...
