Disclosed is a device to prevent wrong manipulation in the range shifting of a vehicle, capable of improving the convenience of driving and the durability of a transmission while preventing a shifting shock by normally shifting a speed from a lower stage to a higher stage when performing the range shifting of a multistage manual transmission for a vehicle based on driving information of the vehicle. The device includes: a first switching valve (100) including a working pressure application port, and switching a port by being interlocked with a range switch (54) of a gear knob (50); a shut-off valve (110) including the working pressure application port, and switching the port in a shifting procedure in which the gear knob (50) moves along a shifting pattern (56); a second switching valve (120) switching the port by being interlocked with the range switch (54); a range actuator (130) enabling the range shifting with working pressure provided depending on the port switching of the second switching valve (120); and a safety control valve (140) limiting a working pressure signal, outputted from the first switching valve (100) to the second switching valve (120), by receiving a blocking signal based on vehicle speed information. |
