    Transmission woes

    Sorry to most likely rehash a sore subject. Has anyone successfully done the TSB 18-NA-355 on their 2015 8 speed transmission? I'm ready to do anything to get this truck to shift like it should. I'm at 90k miles so no warranty. What would dealer charge to complete this?

    Shark fin antenna replaced diy

    I was able to replace the antenna. It was a tight fit but just enough to reach up under the headliner. You can see how corroded the old was. Sent from my iPhone using Tapatalk

    Shark fin leak

    Hi all, My 15 Denali shark fin started leaking a little. GPS, compass, and on star no longer work. I went ahead and sealed around it for now. I’m out of warranty in this truck. Is there one route better than another to get this fixed? Thanks! Sent from my iPhone using Tapatalk

    Just ordered inTune i3 for '15 Denali

    I'll be receiving next week. I plan on trying out the 93 oct tune first. Is there anything I need to be cautious of before applying? What's experience with this on their Denali? Thanks. Jason

    2015 Yukon Denali headlight

    Hi, This is my first post. I looked but couldn’t find any info on my particular issue. My Denali passenger headlight will not work correctly. It flickers 3 times then stays off. The led running lights are fine. Any ideas? Thanks Jason Sent from my iPhone using Tapatalk
