Claims

[Scope of utility model registration request]

It has two cylinder chambers separated by a piston that is mechanically connected to a control lever provided in the driver's seat, and by introducing pressure fluid into the cylinder chamber and applying fluid pressure to the piston,
In a transmission equipped with a boost actuator that reduces the driver's shift operation force, the transmission includes a shift operation force detection means that detects the shift operation force applied by the driver to the control lever, and a clutch disengagement means that detects the engagement and disengagement of the clutch. a neutral position detecting means for detecting the neutral position of the transmission; and a neutral position detecting means for detecting the neutral position of the transmission; and a neutral position detecting means for detecting the neutral position of the transmission; and a neutral position detecting means for detecting the neutral position of the transmission. A gear shift boost control device for a transmission, comprising: a control means for outputting an operation control signal for the boost actuator.
