Hey guys, so I've tried a couple times and I think I'm missing something here.

 

When I move the shifter down to "L" and can use the (lets be honest.....lame) toggle switch on the column shifter, if I select a gear, when I push the throttle down, it automatically downshifts out of the gear I have selected?

 

I've tried it in "Tow/Haul Mode" as well, and it does the same thing?

 

WTF am I missing here so it stays in the gear I select?

 

Thanks

Transmission won't go any higher than the gear you select. The only gears you can manually select and not have it shift are 1st and 2nd I believe.

It will not shift early, it will let you hold the gear till rev limiter. You select a gear say M5 it will go up and down like normal just wouldnt pass M5. It's good for keeping it out of V4.

Guys i think he wants to select a high gear and not down shift, maybe for snow or ice use. Can we do that? I understand it won't let you start in 3rd from a start but shifting up quickly and being able to use the throttle with out a lot of torque or gear can be helpful.

Bingo.

I don't want the transmission to downshift.

In my other cars and my only other trucks I've owned (2013 and 2014 Ram) you could be going say 30-35 mph and manually select 4th gear.

Then press the pedal down (even to the floor if you want for slow acceleration) and the transmission will not kick down to say 2nd or 3rd which if you are on snow, ice or even rain, can cause the rear tires to break loose and set off traction control.

Is this NOT possible in a GM truck?

The term "manual" can be misleading however I can't suggest a better term. Your owners manual has a good explanation of how this feature operates.

Sounds kind of silly, but do you have 4WD? If so, just put it in AUTO when in snow or ice and maintain a safe following distance from the vehicle in front of you. My truck seems to keep the transmission in the highest gear possible at any speed, no matter what setting I have the transmission on.

Dang! GM really needs to get with the times (of a decade ago) with electronics/technology in many areas.....this is not great.

There is absolutely zero reason why you shouldn't be able to have it actually STAY in the gear you manually select when pushing down the throttle. There is no purpose of having the option to choose what gear you want to be in if it's going to kick down a gear or three when you press the throttle down!! Ugh.

That would work with lower TQ. engines, high TQ engines would burn up the trans.

To suggest that GM has to get with the times because of how the "M" function works is a curiosity. It works for me exactly as described in the owners manual. GM has offered transmissions that were fully manual c/w foot operated clutch and also automatics with the D 2 1 format. This "M" function is different -not better - not worse. If given the choice, I would prefer a fully manual transmission but I understand the reasons it is no longer an option. I would be willing to bet the engineers at GM have their reasons and are current with their knowledge.

Driver, I don't quite understand why the normal transmission operation is so inconvenient for you? Are you really just concerned with spinning your tires on snow? Why do so many people have problems keeping their wheels from spinning? My truck handles great in snow. I was passing tons of cars in our 7" storm this Sunday and I felt confident in the vehicle's handling. You just can't FLOOR it when there is snow on the road.

At my house, pretty flat. Though I'm not sure why that matters. When I drive up a snow covered incline, I do not put my foot flat to the floor. There is a lot of throttle between 0- FLOOR IT!

 

I guess if I was driving up a mountain logging trail that was not plowed I may have problems, but those type of "roads" aren't meant to be accessible to the public either.

 

I'm just trying to figure out how an automatic downshift is detrimental to the OP. For normal road driving? Or is it a situation or road condition that should just be avoided?

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
