TRANSMISSION DAMAGE

FORD:
2005 F-Super Duty

ISSUE
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.

ACTION
Reprogram the powertrain control module (PCM) and transmission control module (TCM) to the latest calibration using WDS release B33.6 or higher. Calibration files may also be obtained at the website. 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.
