  1. Shake or Vibration Issues

    I have read there’s a class action suit working it’s way through the system for 2014 - 2018 eight speed tranny’s. So, I would be cautious about doing DIY work for awhile. btw, I had the tranny flush per the new SB with the new Mobile 1 Blue Stripe ATF. My issue was hard shifts in the lower gears. So far seems to have fixed the problem. 🤞
  2. As I mentioned upstream, the new and improved ATF has eliminated both problems in my truck. Here’s some info about this magic elixir. Btw, there’s a SB out in the ATF and change out procedure. https://gm-techlink.com/?p=11127
  3. There are two distinct and separate tranny problems. One is hard shifts, primarily in the lower gears. In my case, it was primarily between 1st to 2nd and 2nd to 1st usually when slowing way down for a yield or right turn or a California stop. The other frequent problem is torque converter shudder, in my case it was the most obvious while driving at mid-speed, say 40 ~ 50 mph. I think the torque converter problem is the most difficult to diagnose because the Silverado rear suspension (leaf springs directly mounted to frame) is pretty much the same as was on my grandfathers 1952 Chevy and on concrete roads with tar strips and antiskid groves and such it’s difficult to tell what’s what. . Anyway, GM is long overdue for an upgrade of their 1500 rear suspension. system.

    You should be getting around 40 ~ 42 degrees. Are you using an ac thermometer? Looks like one used to take temp of a roast, only smaller. You can buy one at most any auto store for about $10. I have four cars in the fam and three, includes my Silverado. test in the above posted range. My wife’s 2017 BMW tests about 38 ~ 39. Don’t know method you’re using or what you’re using to test but 49 ~ 50 isn’t very good.

    What temp are you getting at one of the center vents? Just curious.
  6. Yes. Read my post a couple up.
  7. Took my 2015 6.2/8 spd Silverado in for an oil change a couple weeks ago. While talking to Customer Service Rep I mentioned that my tranny was still shifting hard between 1st to 2nd and vise-versa at low speeds. And, the three quick-flash reprogram hadn’t fixed anything. Also stated if they couldn’t come up with a fix I was going to demand a new tranny. Rep, said that a new tranny might not correct the problem as they have made some swaps and customers still had the problem with the new tranny. Then, he stated that there was a new ATF out that was giving excellent results. Said it was Mobil 1 Blue Label. I said let’s give it a try. So, long story short, they did the flush per the SB and put in new Blue Label fluid. Almost immediately I could tell a difference. And, now that I’ve put about 100 miles on it the shifts are smooth. Haven’t had a single hard shift since. Fingers crossed 🤞!

    Too funny 🙄! Reminds me of some of my grandfathers repairs on his 1953 Chevy back on the farm. He always kept a bunch of bailing wire hung over one of the stakes on the pickup side boards. Was always wiring something together. This was pre duct tape era or I’m sure he would have had a roll laying on the seat.

    Thanks. Personally, I think the condenser failure problem occurred frequently enough to justify a recall or extend the warranty on it out to perhaps 7 yrs/100k miles. Fortunately for me my condenser failed around the two year 28,000 mile marker. So, got a new one plus loaner use. Because this is/was a specific easily identifiable problem (vs mysterious Chevy Shake) I would have liked for GM to take the same approach that Hyundai took with their Sonata engines that had crank shaft machining problems, apparently shavings were left when Oiler holes were drilled. Anyway, my daughter has a Sonata with this problem and got a new (not a rebuilt) engine top and bottom with extended warranty out to 12 years/120k. Just a side-note my condenser went out while towing my 6,000 lb TT down to Big Bend. Also blew out my TT AC unit. But hey, it was only 117 degrees. But, my wife, having her A game on booked us at Lajitas Resort and Spa. Kinda toasty driving back to DFW though 😝...

    I have a BA in Economics, accounting thru Cost (GI Bill plus night shift at a truck stop); anyway, Good Will is a line-item expense that’s forecasted and budgeted on many P&L’s. So, obviously use of Good Will money is reserved for issues that have a high probability outcome such as with you and your family. That’s why I made an earlier post about relationship management. I’ve managed accounts both as a supplier and a customer and have found that there’s usually a positive result, either way, to leave the other party with their dignity. Just my two bits lol 🥴 ....

    I have asked for “Good Will” compensation a few times over the years. It’s a negotiated amount, sometimes offered at the dealer level and sometimes at the corporate level. I’ve had the best results when I’ve used a reasoned approach. Basically, you’re saying to the dealer or corporate rep “our relationship is worth preserving if you’ll work with me”. In turn, they are making the same assessment about you. So, if you go in guns blazing with kick-ass attitude your chances of generating any “Good Will” relief is about zero. No need to suck up, just be reasonable and mind your manners. Mama said 😉....

    You know, I Read a lot of trash talk about bad/unethical dealers. But, happy to say that hasn't been my experience. I’ve been buying from the same dealer for about twenty years. So, maybe there’s something to building relationships? Seems to work for me.

    My condenser on my 2015 LTZ went out summer of 2017 I believe it was. This was about when condensers first started failing as the new and improved version was on National backorder. I had to wait about two months for replacement to arrive. However, truck was under warranty and was provided a loaner while waiting. Good news I’ve had no issues since. Just goo cold air. In fact, checked temp at center vent the other day when temp was above 90. And was getting about 41 ~ 42 degrees which is about right on spec. Only car in the fam that does better is wifes 2017 BMW 430i which will putout about 39 degrees.
  14. Shake or Vibration Issues

    Got to thinking about this and recalled that American Axle, located in Mexico, was originally the manufacturer for GM light trucks, suv’s, etc. per attached article in 2017 manufacturing of these axles was moved back in-house and relocated in Detroit area. Below is an article about it. https://www.detroitnews.com/story/business/autos/general-motors/2017/01/17/gm-grand-rapids/96680568/
  15. Shake or Vibration Issues

    Two or three hundred pages back a poster was convinced that axle run-out was the holy grail of the Chevy Shake and ranted endlessly that was the problem. So, if you do a search you’ll find plenty of opinions about this. Just a side note; I check on the 2019 forum every now and then and have not noticed any comments about “The Shake”. So, whatever changes GM has made may have solved the problem. Maybe the place to look for solutions are the changes made to the 2019?
