I have read the claim that
modern automatic transmissions cut fuel to the engine on downhill stretches, thereby making it more fuel efficient to go down a large hill in drive than in neutral.
This is one of the keys elements of the hybrid powertrain and is why RX 400h eliminates the «shift shock» that can typically be felt as even the most
refined modern automatic transmissions change gears.
As with a standard automatic transmission, or
a modern automatic transmission with torque converter, it is possible to change gears manually at any time with the Duonic dual - clutch transmission by briefly pressing the joystick selector lever on the instrument panel.
It seeks to combine the advantages of a conventional manual shift with the qualities of
a modern automatic transmission by providing different clutches for odd and even speed selector gears.
Modern automatic transmissions are quite different than the older ones mechanically.
Modern automatic transmissions have vestigial gear shift levers.
A modern automatic transmission, though, will typically get better fuel economy than the manual, and that gap widens with the availability of a continuously variable transmission (CVT).
Lockup torque converters and other improvements to
modern automatic transmissions have made many of them more efficient than manuals, and that's certainly the case with the CR - V.
Modern automatic transmissions, such as the Allison 1000, are far superior to manual transmissions in almost every category.
