Technician A says that a reaction member keeps a part of the gearset from rotating. Technician B says that a reaction member is always applied by hydraulic pressure. Which technician is correct? A. Technician A. B. Technician B. C. BothTechnician A and B. D. Nether Technician A and B.

In the automatic transmissions, the idea is to increase the torque between the driving wheels and the engine by providing a forward and reverse driving range.

The torque converter transmits power from the engine to the transmission and with the help of the hydraulic pressure in this device, power will flow to the shaft. In this case, the input shaft will make the planetary gears to have different gears,which are the neutral position and a reverse one.The part of the gearset kept from rotating is the one attaining the neutral position.
