Abstract
A method for controlling a pneumatic actuator () of a transmission having at least one sealing element () that is arranged between two elements () of the actuator () that move relative to one another, and within a specifiable operating temperature range in which a leakproofness of the actuator () is ensured. The pneumatic actuator is acted upon with compressed air from an air supply system for actuating a transmission component. When a temperature of the actuator () is below a glass transition temperature of the at least one sealing element (), the actuator () is acted upon with pre-heated compressed air from the air supply system to warm up the at least one sealing element () above the glass transition temperature.
