When I tried this the first time I really never noticed a change but when I do it now I can feel the downshifts are a bit tamer but still really noticeable.  What are you experiencing when turning off grade braking?  

When I first started using the button to turn off grade braking it did take care of the occasional clunk when downshifting for me. The shifts were a bit snappier when I PULLED THE SHIFTER DOWN UNDER D,  but I long since went the route of a tune for complete satisfaction. I really wasn't looking for more horse power from the tune, just wanted my trans to shift like I thought it should.

It does now.

So which Tune did you purchase and install?

I went with Black Bear custom tune. Justin sent 1st tunes and I asked him to crank it up a bit more. Second TCM tune was a keeper.

Can you still feel your downshifts after the tune when slowing down or not?  What I am feeling is a very firm bump with a 200 RPM rise at approx 40mph, 30mph, 20mph and almost stopped.

I no longer feel any downshift. For me it was only occasional before the tune: Less with grade braking disabled. Now it is gone altogether.

i love it in Manual 4-5, perfect for stop and go city driving. automatically disables the cylinder deactivation, and increases the clutch pressure so the trans runs very cool at 145 degrees. On the freeway i leave it in Drive, it's great for gas mileage , but there is too much clutch slip and the trans overheats and runs 190 degrees.

For those with a 2017 and the 6 speed...

 

How many miles did it take for your truck to shift better?  I am at 400 miles now, and it is very clunky on the downshift, worse than it was at 100 miles....

 

Anybody have any insight as to how long the learn mode takes?  I hope it gets better.

Does it do any damage to drive the truck in manual 4-5 constantly in city driving?

No

Same as a stick shift in 4th or 5th gear.

Well, almost the same as a stick. You don't have to downshift just set it in 4th or 5th and it prevents overdrive and the V4 mode. I believe it tightens up the shift pressure also.

Not a bit.  My 2013 1500 and my 2015 2500 spends the lion's share of its time in 4 or 5 manual mode.  Not necessarily because of the AFM thing with my 1500, and my 2500 doesn't have AFM.  Mine is more about the rolling hill rural area I frequently drive in.  Keeping it out of top gear and there is a lot less gear hunting going on and shifting on every little mole hill.  Saves a lot of wear on trans, actually does better on mpg, and trans temps stay quite a bit cooler. Only time I let it go into top gear is on the 4 lane highways.

Does anybody with a 2017 have a downshift clunk from 2 -> 1?  

 

I know the 2017 8 speeds had a software update, has anybody with a 6 speed had their TCM updated?

Manual mode allows for more driver input but comparing it to a "stick" is  a stretch,  imo.  Some characteristics (including the name) may mimic a manual transmission.

I feel my 2017 six speed has actually gotten clunkier over time. At 8500 miles, I'm not real happy with highway shifting. When I hammer the pedal to pass, it kind of hunts and hesitates.

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
