Abstract
A clutch control method for a fluid torque converter of a vehiclar transmission which has a clutch for mechanically connecting the input and output sides of the fluid torque converter within a predetermined vehicular speed range by such a relatively low engaging force as to allow slippage of said clutch. The control method includes a step of determining that the throttle opening of the engine has been decreased at a rate higher than a predetermined value and to a value lower than a predetermined reference throttle opening, even if the vehicular speed is within said predetermined range for allowing clutch slippage, and then increasing the engaging force of said clutch to a value higher than that for said reference opening to provide vehicle braking by the engine.
