Abstract: A transmission shift device for a transmission having a range group transmission and a shift lever with a superimposed H-shaped shift pattern in which a shift and selector shaft is operatively connected at one end with the shift lever and at the other end with a shift mechanism. A blocking device, which is actuated by, prevents or makes inadvertent transmission gear shifts in a range group detectable to the driver so that the shift and selector shaft is independently shiftable from a first shift gate to a shift gate of the next two lower gears. The transmission shift device prevents undesired incorrect gearshifts in a range group shift as well as making it possible to downshift across several gearsets by making the force of displacing the shift and selector shaft changeable over the regulated distance to the shift gear of the next lower gears.
