The phrase "shift gate" refers to a physical barrier or pathway in a car's gearshift. It guides the driver to smoothly change gears by restricting them from accidentally moving the gearstick in the wrong direction. Full definition
A four - speed automatic with manual shift gate was the sole transmission. (autofile.ca)
The one thing I would prefer is a more precise - feeling shift gate with the six - speed manual. (cnet.com)
There is also a control mechanism that closes the reverse - gear shift gate depending on vehicle speed, to guard against shifting errors. (motor-prime.com)
