5、replaces the conventional clutch. It has three functions:It allows the engine to idle with the vehicle at a standstill, even with the transmission or transaxle in gear.Tt allows the transmission or transaxle to shift from range-to-range smoothly, without requiring that the driver close the throttle

6、during the shift.It multiplies engine torque to an increasing extent as vehicle speed drops and throttle opening is increased. This has the effect of making the transmission or transaxle more responsive and reduces the amount of shifting required.There are two pressures which affect the operation of

7、 the shift valves. What are they?One is the governor pressure which is affected by vehicle speed. The other is the modulator pressure which is affected by intake manifold vacuum or throttle position.What are the three elements of a planetary gear set ?The three elements are: an outer gear that is sh
