    Derali trans cooler installed in Denali

    Towed with it yesterday, not the fully loaded trailer or stop and go interstate but even so, never got above 180. In the past it would have been 200-220. As long as I can keep it below 200 in worst case conditions I'll be happy, 220-225 is just too hot. And yes, both coolers are being run...

    Derali trans cooler installed in Denali

    After I saw trans temps top 220 last weekend, the first thing I did immediately after getting home was to order a Derali trans cooler along with a Derali GM cooler adapter. Folks at eTrailer.com are great, have dealt with them for years and their customer service plus technical knowledge is...

    Towing temps hit 220 this past weekend

    I'm sure you're fine. Good friend that I race with has a 2009 Tahoe that he uses to haul his race car on an open deck aluminum trailer, all in weight of about 4500 lbs. In the traffic we hit last week when I was at 220 he was running 195, and he's usually in the 190-195 range when towing...

    LATCH Install on drivers side rear bench

    Very strange. I just checked the 2nd row bench in my Denali and same thing. I cannot imagine why.

    Towing temps hit 220 this past weekend

    Pulling about 6800 lbs- race car, quad, 2 sets of wheels and tires in enclosed trailer- got stuck in stop and go traffic on the interstate so the Denali was shifting between 2nd and 3rd a lot. Outside temp was close to 90, a/c on. With all the trans gear changes the trans temp touched 220...

    Wow, '13 Denali Bose blows away my '09 Denali Bose

    Build date of 8/2012 so it's a year old. Then again, I think all rental vehicles are rode hard and put away wet. Which is why I'd never buy one.

    Nav confusing left and right

    LOL Actually a search of a few other forums seems to show there's a bug in the software that requires new software. Nice way to get people to buy a new CD.

    Nav confusing left and right

    4 times this past weekend on a three state trip my Nav voice told me to turn left but the screen showed right. And I knew it was supposed to be a right. Up until this weekend it's never done that. Dealer- "couldn't duplicate the problem so no problem found." Anyone else ever have this...

    Wow, '13 Denali Bose blows away my '09 Denali Bose

    My ex picked up a '13 Denali with 13,000 miles on it- no she didn't buy it to replace her MDX, it's a rental from Enterprise. She needed more room for a business trip and this is what they gave her. She's driven my Denali plenty of times so she's familiar with all the controls, but as we...

    trans service interval?

    I do a trans service every 2 years but I tow a trailer. $250 for a trans service is cheap insurance compared to the cost of replacing a trans. I did front and rear axles at 50K And don't forget flushing your brake fluid. Most manufacturers suggest every 3 years but only us racers tend to do...

    Why can't GM offer engines like all the other manufacturers?

    We're still stuck with the 5.3L or the 6.2L in SUV's, or 5.3 or 6.0 in 1/2 ton trucks. Ford offers the turbo V6 in their 1/2 tons and some SUV's. Just drove an F150 with that new engine while pulling a 4500 lb trailer and it pulled better than my Denali. That engine makes 420 lb-ft of...

    Hawk LTS pads eat rotors

    I just talked to one of the engineers at Centric. His recommendation was to stay away from the 306 compound Fleet pad for any street use. It's formulated for police cars, fleet trucks etc where noise and life aren't a big concern. His thought was that they'd be as noisy as the Hawk LTS pads I'm...

    Hawk LTS pads eat rotors

    Yes, Stoptech slotted rotors, cryo treated. No warping at all, just lousy rotor life. Not sure if that's the LTS pads or that the Stoptech rotors are softer than OE, but the stock pads and rotors that I took out at 39,000 miles were silent, no warpage and both the pads and rotors still had...

    Hawk LTS pads eat rotors

    Good find. Let me know if you go that direcdtion and where you find them. I just called my contact at TireRack since they distribute Hawk and Centric, but they can't get the 306 compound since it's a fleet pad. ---------- Post added at 06:34 PM ---------- Previous post was at 06:03 PM...

    Hawk LTS pads eat rotors

    Yes sir, same way I've bedded in my SUV, performance car and race car brakes for 30+ years. And in the case of this vehicle, I started with all new pads and rotors on all 4 corners, yet get noise from all 4 corners. I think the LTS pads are happier when loaded and really hot. When I've...

    Hawk LTS pads eat rotors

    No, up to 35,000 miles I ran stock pads and rotors. Love the LTS pad bite even in the cold winter months, and I could live with the rotor life too, I'm used to BMW SUVs that need pads and rotors every 18000-20000 miles when towing. It's the LTS noise in the hot summer months that gets on my...

    Towing and safe transmission temperature?

    Pulling my 6800 lb race car trailer I'll see 210-220 trans temps if I leave it in D. So I pull it into Manual mode and leave it in 5th to reduce the trans hunting between gears. And on long grades I'll put it in 4th for the same reason. If I hold a lower gear the trans temps rarely get above...

    Hawk LTS pads eat rotors

    After a year of putting up with the squeeling from my front Hawk LTS pads on Powerslot rotors I took the time to pull apart the front brakes to clean and re-grease (with the Hawk brake grease) the caliper slides and the back of the pads. Found two things that bothered me. First, the backing...

    Complete Waether Tech Floor Mat Set With Aisle?

    I'm fortunate to be just 20 min from the Weathertech factory so I just go there to get my stuff. But they have a great tech staff that can answer your questions if you give them a call. And fwiw, ALL their mats, equipment and even the raw plastic are 100% American made. Plus they make the...

    2008 Yukon XL sagging with trailer

    I'll also echo the need for WD system. And if you look at your hitch I believe that the tow rating for dead weight towing is just 5,000 lbs so you're far beyond what is approved by GM or is legal in most states. If I try to tow my 6500 lb race trailer dead weight for more than just a few...

    Resonator delete or MBRP full exhaust?

    Yea, who would have thought. :doh2: Seriously, several friends with 5.3's have done it and have been happy with the results. I've ridden in on '11 Tahoe 5.3L while pulling his race trailer and there was absolutely no resonance. Another friend with a 5.3L NNBS Suburban, same thing. Must be...

    OEM Denali Wheels Peeling

    I've replaced one peeling wheel on my '09 Denali. Friend with '08 Denali XL has replaced several wheels. Another friend with an '07 Denali had to replace two wheels. GM did nothing to assist any of us with the insanely high cost for these wheels either. My dealer said it's very common after 4 or...

    Resonator delete or MBRP full exhaust?

    I removed the rear resonator on my 09 Denali and found absolutely zero difference in power. But the resonance at 2200-2400 is now prominent, and annoying when towing my 6500 lb trailer. Coincidentally tomorrow I'm going back to my exhaust guy and having the stock resonator put back on. Lived...

    Added Tru-Cool Tranny Cooler, Coolant or Tranny Fluid

    Can't directly speak for the '11 with no tow package, but every GM vehicle I've owned worked this way.... The hard lines plumb trans fluid through a separate core section in the radiator, so the only fluid in those lines is trans fluid, not antifreeze. The trans pump moves trans fluid to the...
