Power Take-Off (PTO)

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Failure to install the wire from the powertrain control module (PCM) pin 322 to pin 294 will result in low line pressure leading to PTO and transmission failure.

Some 6.8L and 6.0L SuperDuty vehicles have power take-off (PTO) capability. During stationary operation in PARK or NEUTRAL, the torque converter is locked up when the PTO is ON and the engine operates at 1200 rpm. The following schedule shows expected rpm and line pressure while driving with the PTO in use.

LINE PRESSURE REFERENCE

RPM	Line Pressure
625	80psi
800	100 psi
1000	150 psi
1200	150 psi
2500	150 psi

All 2005 Super Duty F-Series vehicles equipped with a 6.0L diesel engine, TorqShift transmission and power take off (PTO) option, built before September 22, 2004, will exhibit insufficient transmission line pressure supplied during PTO operation. Symptoms include lack of torque converter lock up and transmission line pressure below 150 psi while in stationary PTO mode. PTO operation under this condition may result in PTO unit damage and subsequent TorqShift transmission damage is possible.

Reprogram the powertrain control module (PCM) and transmission control module (TCM) to the latest calibration using WDS release B33.6 or higher. If transmission damage occurs due to improper PTO function, follow normal Workshop Manual procedures to diagnose and repair. Clear diagnostic trouble codes if any and verify the repair.
