TM-74 < SYSTEM DESCRIPTION > [4AT: RE4F03C] STRUCTURE AND OPERATION • The drive force from the input shaft is transmitted via the engaged low clutch and turns the rear sun gear for- wards. This causes the rear internal gear to turn backwards, however it is stopped by the one-way clutch. The rear gear turns forward and the force is transmitted to the output gear after being slowed down. NOTE: When coasting, because the front carrier is able to turn forward, engine braking does not occur. • The status of each planetary gear is as shown below.
