PURPOSE: A transmission control method using a clutch engagement pattern selector of a semiautomatic transmission vehicle is provided to satisfy a driver by variably engaging a clutch depending on a travel mode and to offer stability by reducing slip on a slippery road. CONSTITUTION: Upon turning on an ignition key, an engine control unit(28) operates an actuator(14) and unlocks a clutch by manipulating a clutch release fork(10) via a clutch release cylinder. A driver selects a travel mode among a normal mode, a sporty mode and a hold mode by manipulating a button switch. If the driver changes a shift range via a shift lever, a push pull sensor(24) senses the transmission intension of the driver and inputs a signal to the engine control unit. The engine control unit adjusts a clutch engagement timing by deciding the signal inputted from sensors and valves and outputs an operating signal to a drive unit(26) of the actuator. Thereafter, the clutch is released or engaged by the hydraulic pressure transmitted to a release cylinder(12).
