Toyota automatic gearbox manual

Traditional automatics provide smooth driving characteristics, due to a transmission equipped with epicyclical gears, hydraulic clutches and a torque converter; the MMT has none of these features. The MMT is an attempt to provide a small, efficient automatic transmission with all the energy-sapping complexity of the previously mentioned hydramatic derivatives.

In effect, it is a conventional five-speed countershaft gearbox with a robot employed to do all the shifting and clutch work. This system uses permanent magnet motors to control the clutch and gears. The clutch actuator Fig 2 below , which moves the clutch pushrod.

Hall sensors feed back to the transmission control module to inform it of the speed and position of the actuators. Think about the degree of control required to drive a vehicle onto a ramp. The driver has to sense forwards or backwards movement, acceleration, the clutch biting point and engine speed etc. The TCM needs to know the speed of the vehicle, the direction of travel and to be able to pick up the smallest movements.

The sensor detects movement, speed and direction. For all this information to come together there has to be communication between the engine, transmission and brake control modules.

CAN communication allows the TCM system to communicate with and control systems in other areas of the network. The TCM actuates the clutch and measures the end-to-end travel. The clutch biting point is monitored on actuation to account for centre plate wear. This is monitored to account for wear in the selectors and the baulk rings in the synchromesh. It also allows for a strategy to re-attempt a gear selection if gear baulking occurs at the first attempt.

This is a two pedal operation system so there is no clutch pedal and there are two modes: Automatic E and Manual. On some models manual shift controls are replicated on the steering wheel. A shift lock solenoid is incorporated into the selector and the foot brake must be applied to release it. Up-shifting can take place with the accelerator fully depressed; the ECM takes control of the throttle. We have done countless conversions and we have found the primary factor for success is how good the interior looks.
