Correct. NOTHING wrong with using a linear actuator to move the detent from Park to Reverse to Drive. So the pushbutton deal is fine for basic gear selection. Now performance up and down shifting is another thing altogether. Here, rapidly moving between forward gears is best left to a fully electronic solution. Plugging a paddle shifter into a linear actuator on a pre-electronic trans will yield the exact same sloppy, untimely response as grabbing a mechanical floor or column shifter. But with a paddle shifter, the driver EXPECTS gear changes to happen quickly. Electrons are the way to go.
And unless there is some sort of downshift prevention, paddle shifting into 1st at high rpm could lead to over-revving engine or trans failure which in turn could lead to locked wheels--regardless of the shift mechanism. With a paddle shifter, making that mistake is just that much easier. Electronic trans controllers won't let that happen. I stated that I hope that semi-electronic solution has some sort of downshift prevention since the system is not connected to electronic engine and VSS (wheel speed) sensors.
