The shifting mechanism of TC-SST assembly is divided into two systems as the odd number gear axle (reverse, 1st, 3rd, 5th) and even number gear axle (2nd, 4th, 6th). Each mechanism is joined with an independent clutch, establishing a structure with which two 3-speed M/T mechanisms are combined.
WHEN IN P AND N RANGE


In the P range and N range, the 2nd gear and the reverse gear are engaged beforehand with the two clutches kept released.
AT STARTING (P → D RANGE, N → D RANGE)



Corresponding to the operations from P to D and from N to D, the shift fork (for 1st - reverse) is shifted from the reverse gear to the 1st gear to engage the 1st gear. Then, the clutch for the odd number gears is engaged to perform the 1st gear starting.
WHEN DRIVING IN 1ST GEAR



During driving with the 1st gear, the even number gear clutch is kept released, and the 2nd gear is engaged in advance. (During driving with even number gears, the odd number gears are engaged in advance.)
WHEN DRIVING IN 2ND GEAR



The clutch (for odd number gears) is released at the shifting timing in accordance with the shift map, and the clutch (for even number gears) is engaged to perform driving with the 2nd gear.
Because the shifting is performed only by the alternation of two clutches, the shifting time is short, and the clutch does not become completely released during driving.
