    2019 Escalade ESV 10L80 (MF6) hesitating/shuddering

    Transmission exhibiting harsh shifting in all gears (1 through 10) and exhibiting what I think is TCC shudder. Getting a vibration/shimmy especially when feathering the throttle when the torque converter goes into lockup, which feels like driving over rumble strips. Tach RPM does bounce up and...

    10L80 - filled transmission at wrong temp???

    Just paid for a subscription to Alldata DIY...and I think I might have made a pretty bad mistake. When I did a transmission fluid change a few months ago on my 2019 Cadillac Escalade ESV with the 10L80 MF6 transmission, I used instructions for the 10L80 which called for checking transmission...

    My turn to need motor mount replacement (again)

    Looks like it's my turn to need my motor mount replaced on my 2019 Escalade ESV. The is the second time I've had to get this service done; the first time was on my old 2012 Yukon Denali. Pretty sure it's the mount that's very problematic now. Getting a very odd vibration/shimmy when feathering...

    2019 Escalade fuel level wrong

    2019 Escalade ESV. All of a sudden the fuel level is way inaccurate. It has a 31 gallon tank, with a range of about 530 miles. The gauge is digital. I can fill up the truck completely, and while driving, it will "lose" 2-3 miles of range over a short amount of time. The worst I've seen is that...

    2019 Escalade 10L80 transmission fluid change

    I need to do a transmission fluid change for my 2019 Cadillac Escalade ESV. It has the 10 speed 10L80 transmission. I'm at 108K miles. I want to do this myself, but it seems to be much more difficult than I expected. I got all the parts, and a shop said they would do the pan drop/filter...

    2019 Escalade front passenger seat rattling real bad

    Anyone got any advice for the front passenger seat clicking/rattling very loudly? Randomly it rattles to all hell, then other days it's quiet. Basically, when going over any type of rough road, or simply accelerating, that seat or something in that area makes a very loud audible "CLACK" sound...

    Knocking when going over bumps

    2019 Cadillac Escalade ESV. Bought at 24K miles, at that time, had replaced all sway bar bushings. At 104K miles now. When coasting over bumps/rough road, I'm hearing a loud knocking/clattering coming from the bottom left of the vehicle (I think). Can hear it easily with the driver side window...

    Did something get bent (serious question)?

    2019 Cadillac Escalade ESV. I own up to it: I had a real lapse in judgment. Thursday, I took my truck to a shop to get them to road force balance the wheels and tires. It came back that 3 out of 4 failed. Whatever they did, made the truck feel worse, and it was loopy as hell. When I got the...

    New Escalade owner!

    Hey guys! New platform owner. Last week I sold my 2012 GMC Yukon Denali and got into a 2019 Escalade ESV Luxury (with some Premium features!). It was a long time coming; my '12 started to nickel and dime me pretty badly. I ended up spending over $2400 in the course of 2 weeks, and it stranded me...

    2012 GMC Yukon Denali XL: oil leak discovered

Small puddles underneath the truck in the...

    Finally stranded me...

    Last week, I was out of town with my 2012 Yukon Denali XL. I was in Richmond, and I live in Maryland, so it's a bit of a hike. Anyway, I was going back to the truck, and remote started, and it clicked, like it was getting ready to start...and then after 3-4 seconds *reluctantly* started. This...

    AC blowing "lukecold"; HVAC sticker needed

    2012 GMC Yukon Denali XL. Taking it to the shop tomorrow because the AC is "lukecold"; only blows cold when holding engine speed above 2000RPM and going at least 70MPH. Even then, it alternates between blowing cold air and obviously hot air from outside. The problem is, the front sticker under...

    Oil filter seized, destroyed

    2012 GMC Yukon Denali XL. Always do my own oil changes; 15 minute affair at most. Probably done it close to a hundred times. Never, ever, ever had a problem...until today. For some reason, the oil filter seized and would not come off. I use a Mobil 1, M113A. Has always served me well. I put the...

    Brake stainless steel lines questions

    I have the new Stoptech 950.66002 SS lines installed on my 2012 Denali XL, up front. 1. Is there any detriment if the line is not completely straight? What I mean is, it's not kinked, but it's slightly "twisted", so you can see some warpage. Must have gotten like that when I was installing it...

    Front caliper banjo bolt torque specs?

    I'm changing both front calipers on my 2012 Yukon Denali XL. Does anyone know the torque specs for the banjo bolt? I read that it's 30 ft. lbs. somewhere, and then 33 ft. lbs. in another place. Thanks!

    2012 Denali XL: will these wheels fit?

    I have a 2012 Yukon Denali XL. It has the default ALY5304 rims. They are old, and the chrome is peeling. https://www.hubcaphaven.com/p/3568/aly5304-gmc-sierra-yukon-wheel-chrome-9595662.html A buddy of mine has a set of 4 ALY5698U80s that he just took off his 2015 Yukon XL.

    Odd sensation on acceleration from full stop

    Vehicle: 2012 Yukon Denali XL. Awesome truck, about to hit 100K, no issues to speak of, except this. When accelerating from a full stop, I get a very odd sensation. It feels like something on the driver's side front suspension/wheel "lags" behind the rest of the truck. Kind of like a thump, but...

    Just finished a ton of work...ask me anything

    This past week, I did all this: 1. Drained and refilled both front and rear differentials and the transfer case. 2. Replaced the transmission fluid via "transfusion". 3. Changed all the spark plugs and wires. 4. Changed the brakes and bled the entire system. I learned some valuable lessons...

    Really loud creaking from rear

    Hi guys, I have a conundrum. I've got really loud creaking from somewhere in my rear end. This creaking happens over bumps of any kind. It's not as much a squeak, but a loud creaking, and sometimes it even screeches. I tried everything I could possibly think of: 1. Soaked every single rubber...

    Really bad driver side water leak: carpet soaked

    Hey all, I was turned onto this issue a few weeks ago and I've been struggling with it since. I could definitely use some suggestions here. 2012 Yukon Denali XL. I had kept noticing a spot of water on the driver's side carpet. When I was cleaning up the car, I took the mat out and found that...

    Exhaust/vacuum leak?

    My truck is a 2012 Yukon Denali XL. Recently, I started noticing a very loud hissing sound emanating from around the bottom driver's side of the truck. It sounds either like a vacuum or exhaust leak of some kind. The noise is most prominent by the driver's wheel area. Just stand there and you...

    Potential danger: side view mirror help!

    All, I could really use some help here. All of a sudden, my side view mirror (the driver's side) has developed a mind of its own. I had the curb-side assist (park tilt) enabled for just the driver's side mirror. While I was driving home, I went to look at the mirror to see behind me, and saw...

    Differentials and transmission fluids changed

    On Friday evening, I changed both differential and the transmission fluid for the truck. I started with the rear differential. To my surprise, it was quite clean. The front differential was a different story; the fluid that came out of it looked like mud. The transmission fluid was also very...
