The Detroit Diesel DT12 Clutch Actuator (A003 250 9715) is the hydraulic actuator that controls automated clutch engagement in Freightliner Cascadia trucks with DT12 transmission. This genuine Detroit Diesel component receives commands from the transmission control unit and controls the precise clutch engagement force and timing needed for smooth automated shifting. A faulty actuator causes rough shifting, clutch engagement errors, and DT12 fault codes that can ground the truck.

Q: Which trucks does this clutch actuator fit?
A: Fits Freightliner Cascadia trucks with Detroit Diesel DT12 automated transmission. Genuine part A0032509715.

Q: What fault codes indicate a failing DT12 clutch actuator?
A: Common codes include SPN 1043, clutch actuator position faults, and DT12 transmission engagement errors in Detroit Diesel DiagnosticLink.
