    2017 Yukon Denali Shudder Problem

    I have driven about 150 miles on the rebuilt trans. I pretty consistently get a short "weeep" (1/2 second ish) when gently accelerating from about 33MPH after having slowed gently from about 40MPH. I do not hear this at any other similar speed transition. I called the rebuild shop and was told...

    2017 Yukon Denali Shudder Problem

    Work complete! Super fast TAT. The shop is FULL aware of all the upgrades and has applied them. They have been doing lots of 6L80s (I think he said 5 a month) and keeps all the parts in stock. Happy about the service. Barry's Transmission Specialists, South Burlington, VT. I should add that...

    2017 Yukon Denali Shudder Problem

    Just got the call from the trans folks. Full rebuild. With "upgrades", TC, etc, etc. $7k. Ugh.

    2017 Yukon Denali Shudder Problem

    This seems like the right answer. My mechanic despite knowing this was likely a transmission issue, just drove the vehicle then recommended I take it to our local transmission expert. Should have done that to start, since I waited 10 days for the appointment. The local trans experts had the...

    2017 Yukon Denali Shudder Problem

    Thanks for that comment B-train. I had checked the fluid level (running cold) and was right in the hashes. The rig is in the hands of the shop today and we'll see what someone far more skilled than I finds.

    2017 Yukon Denali Shudder Problem

    Along this thread I have seen mixed advice for this issue. One is flush the fluid and life is good. Other is time for a torque converter. I am kind of a fan of try the less expensive way first. 2015 Yukon XL here. I have also experienced a occasional shudder which started happening around 112k...

    Think my HMI is bad

    This describes my issue 100%. 4 months running with an WAMS programmed pair of radio (from 2016 Sierra) and HMI (2017 Cadillac) in my 2015 Yukon XL. One day just as you describe. Occasionally after starting the vehicle the rear camera will work for for 30 to 60 seconds and then off. The radio...

    2015 GMC Yukon XL SLT Apple Carplay?

    I do mean the radio receiver. It is inside the console under the screen.

    2015 GMC Yukon XL SLT Apple Carplay?

    You have to upgrade the radio as well. WAMS can provide them or you can get them on eBay. I did this with my 2015 Yukon XL in January. Just the other day my center console went blank...dash control of radio only. I am working on figuring out what failed, but it could be the salvage HMI I bought...
