I bought a 2019 Colorado zr2 with the v6 engine. Truck had 101 miles when I left the dealer on 3-21-2019 had to have it towed back to the selling dealer on 3-27-2019. On Friday the service department informed me that they would need to rebuild my transmission. The truck only has 417 miles on it. What the hell? How do I get gm to give me another truck? I really don’t want this one back after this. Rebuilt transmission on a new truck?

We've had 2 in for the torque converter shudder on the 8 speed with the V6.  One got a torque converter, the other the fluid flush fixed it.    What engine/transmission do you have in your C

That would indicate you have the newest updated torque converter, and the proper version of Dexron HP installed.  We did a Colorado 2 weeks ago, that got a converter about 6 months prior to that.  We

I took my wife's 2018 Colorado in for its second oil change today (7300 miles and one year old) and told the service writer about the shudder that started some time ago and is getting worse. She said

Bought a new 2019 Colorado zr2. Had 101 miles on odometer when I left the lot. At 417 miles I had to have it towed back to the selling dealer. They have informed me that my transmission needs rebuilt. Granted it’s under factory warranty it I don’t want the truck back. I bought this new so I wouldn’t have to deal with something like this much less after only driving it about 300 miles. How do I get gm to take this one back and get another one?

No news on when my truck will be done. They’ve had it almost 3 weeks. They are rebuilding transmission. I’ve escalated my case through gm, so far they’ve only offered a $500 gift card to purchase accessories for the truck. Dealer keeps putting off the day that the truck will be completed. They do have me in a loaner though. I’m still fighting to get another truck. I still don’t want this one back after transmission going out after driving 316 miles. I drove this truck all of 6 days before this happened. My first payment is due in 4 days and only had the truck for 6 days. I’ll update the outcome.

ok so I am hearing of shudders different places we have 2 trucks in the fleet 2017, 2019 both trucks have a slip at 5mph then a hard shift into what would be 2nd gear ? not all the time a couple a day or when you back out of a space and shift from R to drive when everything is cold. dealer wont acknowledge a problem. started when new and seems to get worse as the truck gets older. no shuddering at high speed

That’s what my 2019 started doing a few days after buying it. Hard shift either taking off or while going into second. They said the pump exploded. They rebuilt the transmission. Guess I was lucky as I wouldn’t want this to go on long enough for the warranty to run out like they seem to be trying to do to you. Keep taking yours back and make sure to get documentation every time. Maybe even try another dealer. I’ve had the truck back for about 3weeks I’ve now got 1904 miles on truck. On my way home today 5-12-2019 it started shifting funny and wouldn’t go into overdrive. Transmission temp fluctuated from 122 degrees to 298 degrees. About 30 miles from home the engine light also came on. Check it with my scan tool and pulled code p0711 which is Transmission temperature sensor. Guess I’ll be going back to the shop to drop of and get a loaner for another extended period of time. The Chevrolet case manager I’m dealing with won’t even call me back any longer. Probably will be seeing a lawyer next.

Hey good thread.  I helped my daughter purchase a 2019 Chevy Colorado with a V6, her first ever new car starting her career with Florida Fish and Wildlife which requires her to use her truck for work..   She has just over 23,000 miles on it and calls me to indicate something is wrong with it ... a shudder issue.  She brought it to the dealer who did a flush and change of transmission fluid and she indicates it is running fine now.  However, I read this thread now researching the issue more and believe by date of manufacture it must certainly have the latest torque converter.  So why is the issue still occurring?  Is there anyway, like by VIN, that I can inquire as to converter model installed?  What is the latest update to this issue and yes I have the same concern that Chevy will just push this along until out of warranty then hit me for a replacement.   I am starting to regret this truck purchase.

Question to all new truck buyers who bought a 2018 Chevy Colorado, you having any transmission issues, like slipping between 2nd and 3rd gear on the automatic floor shiftier or problems with the + and - buttons ?

I have a 2018 Colorado.  When I start the truck there is a loud/obvious thud at the rear axle while in park.  Does not do it  everytime  , about every 3rd startup. There is also an obvious noise when shifting from park to neutral to drive also.  Do you think my issue is related to the torque converter issue?

I WAS considering purchasing a 2019 Colorado during Labor Day... but now have been scared off.  Anyone know if GM has actually started installing "improved" converters in newer model??

My 2017 Colorado is also doing a very hard shift after backing out when cold, and put into drive. Thought I had a bucking horse under me! No issue when warmed up.

Just bought a 2019 Colorado December 8th. It had 34 miles on it when I got it. Noticed the shudder (currently very mild) almost immediately and thought is was just the ride of the truck. Then I figured out I could kind of make it happen. So I did a quick search to find that this is a known issue. Took it to the dealership with 1500 miles on it and told them what it's doing. They took it in and for a day and gave me a rental. Got it back and noticed on the paper work that I turned it in with 1585 miles on it and got it back with 1586 and it was noted they couldn't reproduce the problem so they put air in my tires. Guess what, that didn't fix the problem. I'm going to call them and ask what they did to be sure I'm not crazy and that all they did was put air in my tires that did not need air. The problem may not produce itself in mile. I usually feel it most between 45-65 mph. Also, is this the Chevy Shake? I have seen videos where the whole truck is shaking the entire time. Thankfully I don't have that... yet.

I have 2017.   Shudder started at 4,000 miles. 

Changed fluid and it came back at 5,000 ...

Replaced TC with new grey label mobile one...

Went to march 2020 and shudder back shaking truck like unbalanced tire ..

Per tsb 19-na-355 changed fluid to new BLUE label mobile one ...  

So far running good   

...

This tells ya it's a fluid TC problem for some reason fluid does not work with this transmission.

I have feeling it's going to be thing where you will have to keep changing fluid ?

Currently my 2018 Colorado has been sitting at a dealership with a vibration problem after the flush.The dealer told me they don't have a transmission tech to asses the problem, I told them i would get it towed to another dealership that has a tech.GM customer care did not like that idea because the dealer told GM customer care that it was safe to drive.I told GM customer care that the dealer had no right to tell you if it is safe to drive because they don't have a tech to asses the problem. So i gave them a couple of scenarios to think about. 1st scenario i pick up the truck drive away no problem untill i find a tech to repair the problem. 2nd scenario i drive the truck away, the problem with the vibration causes me to lose total control of the vehicle, i wind up hitting a school bus full of kids killing them all. Ya the truck is still there and it seems no one wants to to get back to me concerning this problem. My son owns the all new AT4 and guess what he has the hard shift problem in his transmission too not sure what he is going to do yet becuase he bought it at the same dealership my truck is sitting at good luck with our problems. Don't be afraid to use my scenarios with your dealership when you bring it in for your problem.

What engine/transmission do you have in your Colorado? 

Mine had the issue with not downshifting and shuddering till you stomped on the gas forcing it to down shift. Especially when slowing down and going around a corner and gently giving it gas it did not automatically down shift. I took it to the dealer and they switched the transmission oil to Mobil 1 Synthetic LV ATF HP and I have now put on 6K miles since then with no issue.

      Sugar Bears 2015 GMC Terrain SLE-2 2.4 AWD

      By Grumpy Bear · Posted

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
