Abstract
The control device for automatic transmissions with an overdrive mechanism engages the brake of the overdrive mechanism while the shift control valve of the hydraulic control device is in the N-position (neutral), so that when the shift lever is shifted from the N-position to the D-position or R-position, the overdrive mechanism is momentarily set for overdrive thereby reducing shocks upon manually shifting.
