The invention provides a transmission assembly clearance specified torque measurement test method, and relates to the technical field of transmission test. The transmission assembly clearance specified torque measurement test method comprises the following steps: S1, checking a transmission when a test is carried out; s2, prototype installation is carried out after the test transmission is ensured to have no problems; s3, the tested piece is installed on a test bench, and an input shaft of the transmission is connected to a driving end of the test bench; and S4, debugging and testing acquisition equipment, and ensuring normal signal acquisition. According to the invention, the output shaft of the transmission assembly is locked, the specified torque is applied to the input shaft of the transmission assembly, and the angle sensor is utilized to directly measure the clearance of the transmission assembly, so that errors of a gear, a synchronizer outer gear ring and a transmission shaft spline in the assembly ca
