A composite piston unit (10) for an automatic vehicle transmission, in particular a double clutch transmission, comprises a shift rod and a control piston provided at each end of the shift rod and designed to run in a respective cylinder, wherein each control piston comprises a carrier and an elastomeric sealing element bonded to the periphery of the carrier thus forming a composite system. Each control piston is securely connected with respectively one end of the shift rod and is designed to have an axial extent of less than 0.25 relative to its diameter.
