A method for controlling shifts of an auto vehicle transmission is disclosed to determine a forward running shifting process and then perform forward running operations if a range switch of the shift lever is made according to a backward running vehicle driver's intention to run forwards, after the driver considers brake pedal manipulation, the engine idle and vehicle's backward running speed at the time of a R->D range switch of the shift lever, thereby preventing the changing shift shock and reduction in strength that may be caused by wear or loss of friction elements, the method including the steps of: discriminating whether a R->D range switch signal has been input while the vehicle is running backwards; detecting the vehicle's running state if the R->D range switch signal has been input; discriminating whether the first speed shifting conditions are satisfied when the detected running states of the vehicle have been determined as follows: a brake switch is turned off, and the running speed is greater than 0 Kph; and performing the first shifting process if all the first speed shifting conditions have been fully satisfied.
