Forward No.2 Shift Input Out put Out put Operation When conduct the operation of forwarding No.2 shift, K4 and K1 clutches are engaged. The power transmitted from torque converter to driving gear was transmitted to the output shaft. The main and auxiliary friction discs inside the K4 shift and K1 shift clutches are compacted by the oil pressure applied into their cylinder block via the piston. The power from torque converter is transmitted from driving gear to K4, clutch gear via the KV shift clutch gear and counter gear, the power is then transmitted from driving gear to KV, K1shift clutch case through K4 clutch via K4, K3 clutch case and KR, K2 clutch case.
Because the K1 shift clutch is engaged, so the power transmitted to the KV, K1 shift clutch case is transmitted from K1 clutch gear to K2 clutch gear, K3 clutch gear and output shaft gear via the K1 shift clutch, then is transmitted to output shaft. 20-32
