Claim:
1. A transmission device of a vehicle using a transmission, the transmission having a reverse gear position and a 1st speed gear position arranged opposite to one another, a 2nd speed gear position and a 3rd speed gear position arranged opposite to one another, a 4th speed gear position and a 5th speed gear position arranged opposite to one another, and a 6th speed gear position, with shift blocks configured to shift into the gear positions by a shift operation, the transmission being configured to perform a select operation and then perform the shift operation of the shift blocks for an automatic gear shifting, the transmission device comprising: the shift blocks including a shift block of a reverse-1st speed, a shift block of a 4th speed-5th speed, a shift block of a 2nd speed-3rd speed, and a shift block of a 6th speed arranged in a direction of the select operation; first to fourth shift levers configured to engage with the shift blocks, a first shift cylindrical body which is rotatable into a position to engage the first shift lever or the second shift lever; a second shift cylindrical body which is rotatable into a position to engage the third shift lever or the fourth shift lever; a first select actuator configured to control the rotation position of the first shift cylindrical body and select the position at which the first shift cylindrical body engages the first shift lever and at the position at which the first cylindrical body engages the second shift lever; a second select actuator configured to control the rotation position of the second shift cylindrical body and select one of two positions at which the second shift cylindrical body engages the third shift lever and at the other position at which the second shift cylindrical body engages the fourth shift lever; a first shift actuator configured to move the first or second shift lever by the shift operation; a second shift actuator configured to move the third or fourth shift lever by the shift operation; a gear disengagement determination unit configured to determine whether a gear disengagement is made at a desired gear position when the gear disengagement and a gear engagement are performed on the desired gear position by the first and second shift actuators; and a drive unit configured to drive one of the first and second shift actuators which is used for the gear disengagement, and drive the other of the first and second shift actuators which is used for the gear engagement when the gear disengagement determination unit determines that the gear disengagement is made.
