The Chelsea 249FMLLX-K4XP or 249FMLLXK4XP is a 249 Series Power Take-Off designed for Ford Super Duty trucks equipped with the 6R140 TorqShift 6 automatic transmission, in both 2WD and 4WD configurations. It mounts via a 6-bolt Ford pattern and operates with a hydraulic PowerShift actuation system. The 249 Series carries an intermittent torque rating up to 200 lb-ft (271 Nm) and delivers shaft power of 57 HP at 1,488 RPM. Chelsea's patented noise-reduction system makes this the only quiet PTO available for this transmission platform.
