I had the fluid change done at 63k miles after the shudder showed up at 61k miles. The 1-2 was always bad even with the "good" fluid. I've made the switch for all fluids to Amsoil over the last year since it's true 100% synthetic. The trans was the last thing to make the swap, which was only because I was waiting for the new converter. I did about 100 miles today while working, and even without the updated tune file, it drives so much better than factory. Not once did it clunk or slam into 2nd.
Hah! Yeah, I'd been watching each one that he'd listed for over a year at this point, and each time I didn't get around to buying quick enough. Since I was doing the converter, I wanted to have the dipstick too so hopped right on it when I saw he had one listed. Glad he got another one up for you pretty quick after I grabbed that one. From the look of it, it's a bit difficult to reach compared to the typical factory dipstick on the 4l60e and 6l80e.
I picked my truck up from the shop yesterday after having this Circle D converter put in. I also had them install this dipstick that I got off of eBay and changed the fluid over to Amsoil. So far, it's a significant improvement over the factory converter. I'm still waiting on the initial correction from BBP, then I'll datalog and have them get it more dialed in.
https://www.amazon.com/Lisle-18232-Offset-Funnel-Cap/dp/B01HRH2FRO I just bought this funnel a week or so ago and changed my oil shortly after receiving it. I was able to have it held in place by the brake fluid reservoir which gave me plenty of room for the 5 qt jug. https://shop.advanceautoparts.com/p/flotool-16-quart-super-duty-drain-container-42003vmi/10972754-P?navigationPath=L1*14924|L2*15045|L3*16237 I've had this drain pan for several years now. It's never overflowed when draining. I was able to change my motor oil, front and rear diff, and transfer case fluids with room to spare.
You said that you had Jason turn off the AFM when your below 50 MPH. Was that Jason at Black Bear who did that tune for you?
In my experience with my AutoCal on my 16 Denali with 6.2/8spd, I save just over 1mpg with AFM turned on at 50mph and above. I had Justin turn it off for me below 50mph for when driving around town. It's a night and day difference with the BB tune over the stock tune.
Hey fellas, I've been a long time lurker, but since I got my K2XX in December, I find myself here quite regularly. There's a wealth of information and I've utilized it a fair amount already. My truck is a 2016 GMC Sierra Denali 1500. It's got the 6.2l and 4x4. I bought it with 43000 miles on it, and it's at 47800 now. The previous owner ordered it with the CK157 wheels that I love, along with the tri-mode steps. I use this truck for work, so some of my mods will reflect that. Since it's been a pretty wet winter, I haven't really taken many photos of the truck. The first picture is when I just picked it up, and the next was while I was working one morning. Since purchasing it I've replaced the mostly worn tires with Michelin Defender LTX, replaced the factory muffler with the Magnaflow 12909 and removed the resonator after the axle, removed the tonneau cover to allow the use of my Bedslide, installed a Volant CAI, and used my AutoCal from my previous truck to get tuned by Black Bear. As far as performance/engine mods I'm looking into getting a catch can and adding the sensor for E85. Cosmetically I'd like to lower it 2/4 (maybe 3/5) to make it easier to work out of, and I'm hunting for a camper shell to give me more space for my work equipment and to keep it dry, and allow me to carry my 24ft ladder easier. I plan to keep this truck for 10+ years, so I will be proactive with maintenance. I did also have the BG GDI fuel service done a few days ago, and am planning to get the trans, transfer case, and both differentials serviced soon.
I found this on Facebook Marketplace. The guy is asking $50 for it. It looks to be one of the original RX cans. He claims to have the hoses and other stuff for install. Would you guys run a used can for ~$100 after I drive to get it, or should I spend the additional $$ for a new one?
Good morning folks. My name's Matt and I'm from Broken Arrow, Oklahoma. I'm new to posting on here, but I joined quite a while ago and lurked quite a bit. I've had some history with GM. Started with an 85 K5, then a 94 C1500, 02 S10, 06 Silverado RCSB, 04 Silverado ECSB, and 08 Denali. A month ago I sold the 08 and got into a 16 Denali. It's got the 6.2 and 8-speed with only 43k miles. I drove over a dozen trucks when searching for my replacement, and this ended up being the best shifting 8-speed out of all of the trucks I test drove. It was owned by a retired teacher in rural Oklahoma so I trust that it wasn't driven like a madman. I use the truck for my window cleaning business. I already replaced the stock muffler with a Magnaflow and removed the resonator. I also put on a set of Michelin Defenders, both after reading up on them both on this forum. Much appreciated for the info! I'll be getting it tuned with Black Bear since I have an AutoCal from my previous Denali. I'll also add an intake and maybe LT headers.
