Jerky Shifts 1-2 and 2-3
Got my 2014 Mazda6 in April 2013 - 29,500 miles now so I'm hoping for some ideas soon.
It has always had a bit of a jerk from 2-3 at about 18 mph when I am in stop-and-go traffic. It downshifts fine, but when the atx upshifts to 3rd, it sometimes jerks back before it kicks in (normally coming off of an idle at ~15mph). This has occurred since probably 3000 miles - I took it in and the dealer attributed it to the skyactiv transmission and was just a "side effect" of the new technology. It was skeptical, but it wasn't consistent or awful, so I just let it go.
Now I am having the same situation occur (since about 25,000 miles) when it tries to shift from 1-2 while idleing. If it's coming off a stop, there won't be a jerk, but if it is on the downshift/idle, it will often jerk before it clicks into second. I took it in again recently and they attributed it to "gear-hunting" in the computer; they say it's normal.
Maybe this is normal, but it seems a bit odd that it just started doing it from 1-2 in the last 6 months or so. Anyone have any experience or ideas? I'm pretty inexperienced with cars, I just know I've never had a transmission do this in the past.
