I do a fair amount of driving in snow and ice.  This is my first GM in a long while and I was curious if any of you have any tips on using the manual shift feature on the 10 speed transmission while driving on icy/snowy roads.  My previous vehicle was a Tundra and the manual shift feature worked really well on icy roads especially to assist with slowing the vehicle down.  Prior to the full onset of winter I'll be adding weight to the bed to help with traction as I've done with my previous vehicles.  I'm aso going to and test the feature in an icy parking lot at some point but wanted to see what some of you do when your faced with frozen roads.  Thanks

driving on snow/ice covered roads = put it in 4 HI, and operate everything else like normal.

Why mess with manually shifting gears if the roads are actually dangerous? Just increase your stopping distance and use light braking pressure. Maybe buy some real winter tires instead of the garbage that GM gives you from the factory.

 

using your transmission to slow you down instead of the brakes does not change the fact that you are relying the same rubber-to-ice interface to control the vehicle.

Antilock brakes are designed for that purpose. Engine braking on slick roads wouldn’t be advisable. I wouldn’t do it even with 4WD. I’ve used the Auto feature on slick roads. Never engine braking.

Thanks for the replies!  Yes that is pretty much what I do, 4 HI and I've already changed out the tires to snow flake rated tires.  The situation where I've used engine braking to assist with stops are usually at slow speeds and slight declines requiring a stop.  It's not so much my driving its people around me.  There are inexperienced and dangerous drivers that either brake too hard or are driving like idiots (too fast for the conditions, following too close to others, and hard braking in front of you).  Its just the reality of the town I live in.  There is a ski resort near the town and when the snow is good people are crazy to get to the mountain.  There are also icy downhill sections of heavily traveled roadway where engine braking really helps in slowing you down without having to risk sliding from taping your brakes.

As anyone who's driven a front wheel drive stick shift in winter will tell you, engine braking the front wheels in snow is a great way to lose all steering control.  Use your ABS.  That's what it was designed for.  Now, if you're in 2Hi, engine braking on the rear wheels won't send you into the ditch backwards, but why bother when you have some of the latest technology keeping you pointed in the right direction?  You're probably shouldn't be going fast enough to have to worry about brake fade.

 

Does the 10 speed let you start out from a stop in 2nd gear?  That's the real benefit to manually shifting your own gears on ice.

    • Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.   
    • I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future. 
    • Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it. 
    • Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me. 
    • $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
