The invention discloses a vehicle transmission operating control device. The vehicle transmission operating control device comprises a gear selecting/shifting device assembly and a neutral position locator. A vehicle transmission comprises a synchronizer assembly. A synchronizer compression spring in the synchronizer assembly is pressed on a synchronizer pin in a synchronizer sliding gear sleeve groove, and neutral gear positioning of a synchronizer is achieved. The gear selecting/shifting device assembly comprises a shift fork shaft connected with a shift fork, a gear shifting rod connected with a shift head, and a shift fork shaft locator. The shift fork shaft locator is pressed in a shift fork shaft groove through a shift fork shaft compression spring, and neutral gear positioning of the shift fork shaft is achieved. The neutral position locator comprises a shell fixed in the vehicle transmission, a self-locking compression spring arranged in the shell, a self-locking pin arranged on the shell in a sliding manner, and a positioning cam fixed to the gear shifting rod. A surface work part of the positioning cam is provided with a V-shaped protrusion, and a positioning groove is formed in the top end of the V-shaped protrusion. The self-locking compression spring is pressed on the self-locking pin in a matched manner, the self-locking pin is arranged in the positioning groove, and the neutral gear positioning of the shift head is achieved.
