My 2019 Colorado 8 speed V6 (purchased 11/11/18) has a torque converter issue, started at about 400 miles.  They have changed the transmission fluid seemed better for a while then came back.  Took it back (2000 miles) in they had it for 2 days and then I was told that GM knows about the problem they have no fix and have been told not to replace any more torque converters, cause it's not fixing the problem either , was told to just drive it I have a warranty.  Not sure what to do now.  Love my truck but the problem is annoying.  My first brand new vehicle.  Was hoping to not have to deal with any problems for a very long time.  Any suggestions on how to handle?

A lurker on at least three other similar threads.  The key words for you to search on are "Colorado shudder".  Known issue.

There have been multiple attempted fixes over time.  Previous fixes involved older versions of fluid flushed without using or following the latest and greatest "approved" method, so do not be satisified with "it was flushed".  Latest is to make sure service follows latest procedure in TSB 18-NA-355.  Latest and greatest Mobil ATF using a triple flush process requiring a Bosch device that a service department will get over time delivered free of charge to them.  Do not expect the flush to work on it's own as the process details how the Bosch device must be used to satisfy the TSB for the shudder.  Again, do not expect that all dealers have the device yet or have been using it long if they do have it.  Keep following multiple Colorado shudder threads for various updates from various owners.  I was looking to buy at one point :) ...

There is a new, third formulation of the fluid out now.  Get ready for another trip back for them to change it again. 

 

Nationwide rollout of the special tool has already occurred, the only thing you have to make sure is if they have the new fluid.

It is well known, and even acknowledged by GM, that the problems with this transmission cannot be fixed. Therefore, as soon as possible and with as few miles on the vehicle as possible, take it back to a dealer and request the defect be repaired. Do this several times, keeping all records of when, where, action taken (even if none), any advice or comments made by dealer persons, and if possible, record everything on video with sound. Remember it's not the dealers fault you bought a vehicle with a problem that cannot be fixed by any means, but the dealer is the one that's stuck with trying to fix it. Obtain all the information you can find on this problem, and even similar problems in other models (because the same transmission is used in multiple other vehicles), obtain all applicable GM TCB's (such as TCB 18-NA-177 and TCB 18-NA-355) that have any bearing on the problem, and then after a "reasonable number" of repair attempts apply for Arbitration according to the requirements applicable in your state. In Arbitration, which is free to the vehicle purchaser, present all evidence regarding nature of the problem, past history and the manufacturers inability to correct these serious defects, evidence that the issue exists in the vehicle you purchased, and the history of repeated attempts by dealer(s) to fix the problem in your vehicle but that the problem still exists. When is all is said and done, you may be given a refund of the vehicle purchase price, a replacement vehicle having the same configuration and options, a decision to return to a dealer for further repair attempts, or no other action or remedy. In the case of the 8L45 / 8L90 transmission issues, arbitration in many states has already ordered refunds and replacement vehicles, as the problems with this model transmission have been around for so long and are so well documented. In any event, Good Luck.

I must admit I was unaware of this one. But the following is my opinion and nothing else.

 

Never underestimate GM and their legal staff. They will use every tactic in the book, and invent new ones, to delay and thwart any conceivable move against themselves or their interests.

 

For GM, the existing legal actions filed against them, and even ones yet to be filed, will remain in the legal system for decades to come, and in the end, will come to NOTHING. GM will not allow any other outcome.

 

Existing owners having issues with their vehicles will be allowed to complain until end of warranty, at which time they will be ignored.

 

In my experience with Class-Action suits against GM, you'll get better odds buying lottery tickets.

      Towing In Loose Gravel

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.
