Toyota Camry had a learning transmission a few years back with loads of complaints by the customers and no real fix either. I would never buy a vehicle with any learning type transmission because of the complexity and other people within the house hold that may drive the vehicle other then just one person. Good luck to those with this issue. Glad I came accross this thread after looking at a Chevy Nox yesterday. Couldn't drive one since they were all sold at the time. |

The chief engineer of the new Equinox called me today and he is having the engineer that actually designed the tranny program on the Equinox come down from Detroit tonight (I'm in central KY) to drive with me tomorrow. Sounds like he can even load different tranny programs into the vehicle on the spot and I can drive the car and see how I like it. I've been very impressed with the experience with the engineering dept. so far. And it was just because of posting on here that someone at GM put me in contact with them. Maybe they've already developed a fix and don't even know it! Though I guess until now they didn't know of the problem at this high up level. So I'll let everyone know how it goes tomorrow.

Replying to: runox (Sep 18, 2009 6:44 pm) Mind sharing your VIN? I'm meeting with the engineer in an hour (11 o'clock AM EST). Hope you have the automatic notification of replies and get this in time. |

Today I spent 3.5 hours with the engineer in charge of fuel effeciency for the new Equinox (the "ECO" button - he created that). GM sent him down from Detroit (to Lexington, KY - about a 6 hr. drive) specifically to drive with us. Very nice and very smart. Without typing a novel, I'll tell you what happened. It turns out to be a tranny programming issue as the dealers thought. The person who actually writes the tranny program for the Nox works under the engineer who came down. Everything I have described in this thread and others as symptoms it did, which was good. The driving characteristics were rather harsh to him compared to other Noxs he has driven, which are many. He was, however, able to explain why every symptom existed except for one (but the solution fixed that, explained below). He did say that although uniformity in parts and software is the goal, small differences happen during the manufacturing process (and GM largely buys parts from suppliers and doesn't make them themselves) that can make one vehicle a little different from another. This might be why some exhibit more symptoms than others. Without going into specifics, all the symptoms were related to things designed to conserve fuel. Long story short, he put a new tranny program into my vehicle that influences the operation of various transmission and fuel conserving components. It actually was just officially approved yesterday, and will begin to be put into new Equinox production vehicles possibly as early as Tuesday (Sept. 22). My vehicle is the first one with this new program that is not a GM corporate vehicle, and only a few of those have it. The difference is amazing! It drives like a different vehicle. Although the symptoms we experienced while driving the vehicle were either new to him or more harsh than he's experienced before (i.e.: they didn't specifically make this new program to solve the symptoms I've described), this new program makes a world of difference and solves most all of the problems I've described. For those thinking about not buying the Nox because of the tranny issues described - don't be hesitant any longer. I no longer discourage people from buying this vehicle because of transmission behavior. If GM if full of people like this guy they will do great so long as people put their biases aside and actually give the vehicles a chance. For those of you experiencing the symptoms who already purchased one, email me (wallyuwl  yahoo.com) and I'll tell you how I understand to get the fix. They may not release it as a full-blown bulletin (there are what I consider good reasons for that based on what this engineer said), so it might not be obvious to your dealer that there is a fix out there, but they should be able to get and do the fix (though I'm not sure on the timeline) with a little prodding. The fix is literally a 5 minute thing to actually perform.

Replying to: wallyuwl (Sep 19, 2009 5:32 pm) Yet you're comfortable inviting people to contact you "privately?" Perhaps you ought not to have extended the invitation in the first place? Personally, I don't see why you just wouldn't "reveal" the fix if you think you have one. tidester, host SUVs and Smart Shopper
