A power tool includes a housing (302); a motor (306) supported in the housing (302); a multistage transmission (310) operably coupled to the motor (306) to receive torque from the motor (306); an output shaft (314) rotatable about a central axis (318) and operably coupled to the transmission (310) to receive torque from the transmission (310); a clutch mechanism (514) coupled to the transmission (310) and operable in a first mode, in which torque from the motor (306) is transferred to the output shaft (314) through the transmission (310), and operable in a second mode, in which torque from the motor (306) is diverted from the output shaft (314); a shift mechanism (658) coupled to the transmission (310) and operable to disable at least one stage (338, 342, 346) of the transmission (310); and a mode selector ring (634) coupled to the shift mechanism (658) to actuate the shift mechanism (658) in response to rotation of the mode selector ring (634); wherein the clutch mechanism (514) includes a resilient member (566), and wherein, in response to rotation of the mode selector ring (634), the resilient member (566) is compressible to increase the amount of torque transferred to the output shaft (314) during the first mode of operation of the clutch mechanism (514).
