Automatic 2-1 rough downshifting

Maybe, I've always had the worst traffic with accidents on roads trying to get back into Houston. Then again, the first time I was in the state, 5 minutes after leaving the airport there was a bumper damage crash at speed. Everyone kept driving. My dad said that was why I was going to be costing him 2k a year in this state

I'm going to assume that the 2-1 downshift is rough because of the ratios. 1st is a 'pull away gear' that a manual user never downshifts into (street driving) because the ratio is really high. It's designed to get the car moving from a standstill, so the ratio is huge to get the torque to the stopped wheels.

The shift may be more noticeable because the Z is a 7 speed, and so it's relying less on the viscous and instead on making the shift to get the torque curves lined up than say a 4 speed. Then again, our hauler Commander really had some rough shifts at altitude from 4th to 3rd, followed by a very depressingly high rev as it weezed over the mountains.

I think that use will let you know how the computer thinks to try and avoid or mitigate the shift shock with time.
