    My transmission is failing.

    I will let you know what the dealer says, apparently there are no user-serviceable checks on the 10 speed Except for codes.

    My transmission is failing.

    It’s not in my signature, I wrote what it was in the text. The dealer suspects the torque converter and it’s booked in next week for a visit with the “transmission specialist” there. I’ll let you know what I find. It came out of a service/oil change about 10 days ago so presumably the fluid...

    My transmission is failing.

    When I stuck it in gear after having not used it for 5 days, nothing happened until I stuck it in selectable Low (L1) and it moved off. Then I reselected drive and it’s been OK. I had also noticed when I was leaving my parking spot with virtually no pedal pressed because we have a 15 km limit...

    Diode Dynamics SS3 LED Fog Light Kit 2015-2020 Yukon

    Morimoto S are crap. I have them on my Denali and I have flashlights that put out more light. That’s twice Morimoto has gotten me, I put their fogs on my F150 and they were even crappier! I may be a slow learner but if I didn’t say it before, here it is again: Morimotos are crap!

    How old is the battery? My bet is the cold weather finished it off.

    Airaid jr intake tube

    I think it worked perfectly to remove $160 from your wallet… I think that if there were efficiency gains or mpg gains or even power improvements that the marketers could sell, you would see GM using it and marketing it. A lot of their work goes into making the truck quiet and civilized for its...

    (Installed )370a mechman alt & 4800 Xs battery & big 3 upgrade

    Check your battery specs, a fully charged battery should be getting ”about” 13.9 volts so that means the load is light and the alternator is correct. Starting the car should take about 1/2 amp or so (500 amp/hrs for a second or two) so there isn’t much power needed from the alternator to top the...

    Heavy Duty says hello and asks for guidance, etc...

    i bought Bilsteins for my old F150 and they told me there was a good guarantee. Sure enough, they failed, leaked out their fluid. The warranty people required me to remove them and send them in to some Bilstein location and they’d let me know. Heavy, expensive and large, what do you do with a...

    Keep it or sell? Help me diagnose a couple issues please

    I really like my 2020 but as soon as the warranty is up, it’s gone. Trust, confidence and knowing the truck will do what it’s supposed to do every time you get in it is the bottom line. Every vehicle must be maintained and that cost is not insignificant. Engines and transmissions though? I sold...

    How do you guys like the 15-20's?

    Electric cars are the Betamax of this decade, the Lightning is very cool but I believe that every EV bought this year will be in the landfill in 10 years because the battery costs more than the whole car. Having tossed that rock in your pond, I have a 2020 Denali and I love it! I haven’t had it...

    Headlamp upgrade to LED ? '19 GMC Yukon XL

    I have had 2 sets of Morimoto fog lights. I’m a slow learner obviously. First set on an F150 - useless except for colour. Another set on my Denali - also useless. Waste of time and effort to mount them. Expensive too, save your money. If it wasn’t such a pita to get them out I would try and sell...

    Exhaust option for smell

    One truck with no cats is like 200 lawn mowers. Do your part! Porsche gets 500 hp from a normally aspirated engine 1/2 the size of a Yukon, they use cats.

    What is the Difference Between a Corvette 6.2 and a Denali 6.2?

    Same heads? Ecu? I noticed my Yukon doesn’t have a marked red line. How is the intake different? I guess headers of a sort might be helpful with all the rest. Are Corvettes having lifter issues Too?

    How hard does this look to repair?

    Barge pole, as in, “wouldn’t touch it with a…” Running a vehicle like that, after months of work to make it work, as a taxi?It’s the wrong vehicle for Uber, IMHO. Besides, it’s all money out. How long will you have to drive it to break even?

    Tires?

    Nitrogen is a have. Nitrogen is already 70% of the air. There are reasons to use it in aircraft tires and no reason to use it on car tires.

    What is this and how do I get rid of it?

    It looks like mildew. Use a mild bleach.

    2015-2019 GMC Yukon performance full LED headlight

    Morimoto makes crappy nice stuff. The fog lights I put in my F150 are useless and like a Liberal, I still bought Morimoto fog lights for my Denali and they are also very nice but they are useless as fog lights. Be very afraid of Morimoto, they offer lots and deliver very poor light, which is...

    nokian tires

    Excellent winters. I’ve had 2 sets but the first was a Golf and the second was an F150. My friend has the summers on his Cooper S and loves them.

    She just arrived: Summit White Denali: Update: Transmission fixed!

    I actually think (my) white Denali looks more like a chest freezer than a refrigerator…
