So I've known for some time that there was a TCM update for the 2011 Model year Cruzes that fix a lot of the oddities, especially low speed confusedeness, better shiftpoints, smoother shifts, etc.
Finally made an appointment yesterday, and brought it in today. Took all of 2 hours for them to check. At firs they didn't want to do it, saying there was nothing wrong with it. They finally called GM and they gave them the go-ahead. So two hours later I go back to pick it up, and so far, it's better. Low speed driving, start/stops is much better. It actually feels like it disengages the wheels when slowing down, you don't feel the downshifts nearly as much as you could before.
In other words, it doesn't feel nearly as "clunky" in stop and go driving. The shift points are vastly improved, it doesn't want to hold onto 2nd gear forever, and shift quality in general (especially the 3-4 shift) is immensely better than it was. They assure me that it will "re-learn" again, and improve even more. So, I'm quite pleased. I prefer a gearbox that will hold onto higher gears longer when I press the gas down some, especially with an engine with as much torque as this one has, to get up hills. It's more improved in that, it stays in higher gears just as much as I'd like it to.
It was a BCM update that included updates for both the ECM and TCM, and it shows. The engine and transmission actually feel like they are working together, rather than fighting one another, like it often did before. So I give this free update a 10/10 in satisfaction.
