chevrolet Speed Limiter hides vehicle manufacturers defect from consumers

[grizzlyltz]

The 2010 F250 can best 98 mpg in about 1/8th of a mile and best 140 at about a mile. All without being thrown out of a plane. I’d say my Chevy could get close to that if it had a good transmission and no speed limiter! I’m still trying to find out if the tranny speaks Spanish or French??? (Central America or Canada)

What a bunch of bs!!!!!

OH. Is that why there are no service departments at FORD dealerships. Mystery solved.

Ok you all, you are grossly missing my point. If the transmission blew in an unloaded truck at 675 miles, there is no way it could have pulled my trailers, especially with a load. Luckily I cancelled a 500 mile trip because it would not have made it. Also the symptoms began a hundred miles or so before I put the programmer on it. The extra few MPH for a couple miles is all it took for me to know there was a larger issue. The tuner was on there for two days and about 60 miles of which 55 of those miles were within the speed limiters restrictions. Beat me up, call me names, tell me I’m a truck abuser, none of it replaces the fact that the transmission was faulty from day one and was going out no matter what I did. Poor GM quality in their transmissions, most likely built in Mexico or some other cheap labor country. Someone somewhere in the GM manufacturing and supply chain screwed this one up. I just happen to have bought their screwup. 

So you're saying that you knew the transmission was bad before you tuned it? Why tune it with a messed up trans?  Why not take it to GM at that point and inquire about the "symptoms"  that had begun? I apoligize about the politics comment but it seems hard to blame GM here just because they churned out a bad trans at the factory.  Each of the big three can make a mistake from time to time.

Oh WOW! You GM guys are sensitive! No support here despite that my initial request was if anyone else had transmission issues with their Chevy truck. Now I’m getting beat up because I dared to subject MY truck to another 12 MPH and it could not take it. Totally Pathetic! I though Chevy Trucks were built tough. I didn’t know they were to be driven gingerly and while wearing kid gloves! What about the commercials in the 70s and 80s of Chevy Trucks pulling trains, jumbo jets, and mega tankers? I guess that was all fake boasting by GM. Actually it was not. My 76 K10 pulled a 25,000 forklift out of a mud hole while carrying well over 2000 pounds itself and nothing broke! Now the truck they build must not be so tough and rugged. The roll back wrecker will be here in 25 minutes to gingerly haul my Silverado to the dealer. I think I’ll take pictures for my scrapbook of my fragile Chevy, then follow in my Ford!

Brand new 2017 Chevrolet Silverado 1500 LTZ 2WD, 600 miles. Has a speed limiter limiting the vehicle speed to 98 MPH. I installed a tuner to just raise this parameter only. At 99 MPH the truck began a drivetrain vibration that increased with speed. At 100-103 MPH it was extremely bad with a loud sound that filled the cabin and a vibration that felt like the drivetrain was about to fly apart. At 109 MPH the vibration ceased entirely. Slowing down from there the exact opposite happend with the vibration and noise subsiding entirely by 93 MPH. The truck also has developed a loud vibration noise at 52-55, and 34-39 MPH as the torque converter locks and unlocks. It will last as long as that speed and constant foot feed is maintained. I’ve owned many Chevrolet pickups to include a 1990 Silverado 1500 that could go over 140 mpg! I’ve never experienced this vibration and noise before. Could this be a problem on all 1500s that GM is covering up with software? I expect a $51,000 truck to be able to travel at 100 MPH if required without coming apart!!!! Any others experienced this? If so, was it diagnosed? Was it repaired? What was the diagnosis and the repair? Did the repaired problem return later? Thanks, Bart

Okay then lets answer your questions. Yes I've had this happen to me. In a 98 Ford Mustang. Sorry. Difference is when mine started vibrating I didn't push it another ten MPH. It spit a balance weight. Got it fixed and kept going.

 

You kept pushing it until the vibration tore it up by pushing it through and back through a harmonic critical point. Then you found the sore spot and kept hammering on it. And now your whining about a lack of support and the failure of a part to not support that abuse? Seriously? Most people get their hand off the hot stove when it burns them. You pushed harder then blamed the stove and are mad at your siblings for not being mad about it too?

The engine and trans are sourced from the US as per the window sticker..

My bet is that Bart does not even own a Silverado, or broke a tranny. He sounds like a Ford troll coming here to stir the pot.

So what you're telling me is that your truck worked great.  You then put a tune on it and at 99 mph you noticed vibration.  You decided to keep accelerating until there was (and I quote) " loud sound that filled the cabin and a vibration that felt like the drivetrain was about to fly apart".

 

You again, thought it was a good idea to just keep accelerating.  

 

I am sorry but that sounds like a whole lot of stupid.

Ok I’m not a troll. A picture of my truck Saturday a week ago when I bought it. As for kept pushing the truck. The entire test that first discovered the vibration lasted maybe 15-20 seconds. Hardly abuse. The initial noise I heard was not descernable as a problem and occurred 4 days before the failure. I have owned the truck now for 9 days. It had 28 miles on it when I got it and 657 miles when it failed. That is less than 75 miles a day. As for speeding, I’m guilty! However I live in Mobile, AL and commute to the VA in Biloxi, MS. If you are not doing at least 85 on I-10 you will get run over. I also commute to Pensacola Naval Air Station. Same thing in that direction concerning speed of traffic. I dare say I’m not the only one to hit the speed limiter in their truck nor the only one to use a tuner on the truck. Note, the only parameter I bought the tuner for was to raise the speed limiter up to the speed rating of the tires it came equipped with. Further if I choose to break the law concerning speed I can do so. I do not drive reckless. A heavy foot is hardly reckless by itself. One last thing, read the last few lines of my original post. I was asking for information not an inquisition. All I’ve gotten is grief and condemnation. That translates to me that my fellow Chevy/GMC owners on here are afraid to stress their rides even in the least. That means no towing, no hauling, and no 4 wheeling. If this is the new GM family then I will be the black sheep, I guess. Good day to all of you. I’ll never ask for help on this site again. Bart

Bart, sorry about your bad experience with your Silverado and good luck with your new Ford p/u, just remember Ford doesn't want you to haul gravel in the bed, it's delicate after all.

Son you don't understand the nature of 'critical speeds' in harmonics. 2 seconds at the right sympathetic frequency is forever to the parts. In my oil/gas life I ran 180,000 hp. steam turbines I've seen them fail in les than 2 seconds from a ham handed operator thinking just as you are. It certainly is abusive and dangerous. Every spin out in 12 quarts of ATF at 110 mph? I've done it at 55 and it wasn't fun...for anyone...including those who were following and loved the effect of greased glass to drive on.

 

 The initial noise I heard was not descernable as a problem and occurred 4 days before the failure.

 

It happens and its sucks and it was the onset non the less.

Your '76 also has decent paint (probably lead based), doesn't get over 20 mpg and wouldn't pass EPA standards.  It is not completely the manufacturers fault, look at the nanny state as well.

 

If you really were looking for advice or similar experiences you should have left out the Chevy is stupid and weak, Ford is better BS.  People read that and just assume you are being a troll for the sake of being a troll.  Perhaps create a new account a try over, I doubt anyone is going to take you seriously on this one.
