Transmission apparatus and vehicle having the same

A transmission apparatus including an automatic transmission that is mounted in a vehicle and is capable of engaging a first engagement element and a second engagement element among a plurality of engagement elements when shift-operated to a reverse position, and engaging the first engagement element when shift-operated to a neutral position, the transmission apparatus comprising:

• a pressure feeding unit adjusting a fluid pressure of a fluid pressure source and outputting the fluid pressure as a line pressure;
• a fluid pressure input/output unit receiving the line pressure and outputting from a reverse position output port among a plurality of output ports when shift-operated to the reverse position, and blocking the plurality of output ports when shift-operated to the neutral position;
• a first pressure regulating unit receiving and adjusting the line pressure and outputting a fluid pressure which is the line pressure adjusted;
• and
• a selective output unit outputting to the first engagement element the line pressure output from the reverse position output port and outputting to the second engagement element the fluid pressure output from the first pressure regulating unit when shift-operated to the reverse position, and outputting to the first engagement element the fluid pressure output from the first pressure regulating unit when shift-operated to the neutral position.
