In the final section we saw several of the Command approaches that mechanically managed transmissions use. Electronically controlled transmissions have far more elaborate Handle schemes.
The strain on the ATF is regulated by a governor linked to the output shaft, which varies the force according to the auto speed.
The shift circuit To change correctly, the automatic transmission needs to know the way tricky the engine is Performing. There are two other ways this is finished. Some vehicles have an easy cable linkage linked to a throttle valve during the transmission.
The clutches while in the transmission are a little bit more sophisticated. During this transmission you'll find 4 clutches. Every single clutch is actuated by pressurized hydraulic fluid that enters a piston Within the clutch.
