Abstract: PROBLEM TO BE SOLVED: To provide a slip limiting device capable of reconciling operability and an overheat measure by ensuring the overheat measure of torque converter hydraulic fluid, without impairing the operability. SOLUTION: A slip limit of the torque converter, based on a normal region pattern, as shown in Fig (a), is performed except during high temperature times. In this case, a thick solid line, a thick broken line, a thin solid line and a thin broken line show a lockup starting line, a lockup releasing line, a slip control starting line and a slip control releasing line, respectively, and an L/U, an S/L and a figure show a lockup region, a slip control region and a speed gear stage, respectively. At rise in oil temperature, although the rise in the oil temperature is suppressed by reducing slip rotation of the torque converter by the slip limit, based on a pattern for enlarging the slip control region to the engine high load side as shown in Fig. (b) hatched region.  Because vibration will not be generated, even in the high load state due to the enlargement of the slip control region, operability will not be deteriorated also. When the oil temperature cannot be lowered even by the above procedure, the oil temperature is surely lowered by further reducing slip rotation of the torque converter by the slip limit, based on a pattern for making the enlarged region as the lockup region, as shown in Fig. (c).
