Rough downshifting?
Anybody experience this?
When I downshift from 4th to 3rd, it engages in a very rough fashion. No other gears do this.
Any insights?

On a related note, some people actually like it rough; just ask some of my ex-girlfriends.

I brought the car back to the dealership a couple of weeks after I got the car. They said that there was something odd with the TCU values showing up on the computer. They re-programmed it and it fixed the issue.

Had the same issue even at relatively low speed from 4th to 3rd and from 3rd to 4th, there was something weird as if there was a dead zone followed by a push forward (hard to described actually).

It happens at any speed. Especially noticeable when going slow whether I am on the gas or not.

4th --> 3rd, 90% of the time is rough, regardless of rpm's. It's like the car forgets to rev match. The only time it's smooth is if it's at near idle speed.
4th --> 5th at low rpms, same thing. Doesn't matter if it's auto mode or manual mode, feels like a power shift.

Actually it was the shift from 4th to 3rd and from 4th to 5th that was weird on my car when I got it. A visit to your dealership did solve it.
