Select shock attenuation arrangement for an automatic automotive transmission
 In order to reduce select shock the engine load is monitored and if the level is above a predetermined at the time the shift lever is moved from a range wherein torque is not transmitted through the transmission (e.g. neutral or park ranges) to a range wherein torque transmission is enabled (viz., D, I, II, R), the level of hydraulic line pressure is reduced by a predetermined amount for a predetermined period to temporarily reduce the engagement force.
