A MultiMode manual transmission (MMT or M/M) is a type of automated manual transmission offered by Toyota. It uses a traditional manual gearbox with a computer-controlled clutch actuated by permanent magnet motors. Multimode Manual Transmission is available in the Aygo, Yaris, Corolla, Corolla Verso, Mark X and Auris in Europe, and should not be confused with Multimode Automatic Transmission, which is offered in the North American market by Toyota.
Operation
The Multimode Manual Transmission has the following gears: R, N, E, M+, M-. R: R is the reverse gear. It is similar to R in both traditional manual and in fully automatic cars. N: N is the neutral gear. It is similar to N in both traditional manual and full automatic. E: E is the functional equivalent of D in a full automatic. As the gearbox in a MMT car is a manual gearbox, instead of one with a torque converter (as in a traditional automatic), gear changes are noticeable. The accelerator should be eased off, slightly, when gear changes occur. This facilitates a smooth transition, between gears, and allows for smooth acceleration. M+: Up-shifts a gear in sequential fashion, from M1 to M5 (M6 in 6-speed MMT cars). M- : Downshifts a gear in sequential fashion, from M5 (M6 in 6-speed MMT cars) to M1.
