POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED) Some vehicles with 6.8L and 7.3L engines are equipped with Power Take Off (PTO) capability. These vehicles have a special transmission case, internal components and calibration for PTO usage. If your vehicle is equipped with a 7.3L Diesel engine, refer to the 7.3L Diesel Supplement for information on the auxiliary powertrain control module (APCM) and its operation. The PTO can be used during mobile and stationary continuous/intermittent applications. PTO operation is disabled while the vehicle is in Overdrive (the TCIL will not be illuminated), in N (Neutral), during engine cranking. Transmission upshift and downshift schedules will be reduced by about 15% and will have a firmer shift feel during PTO mobile applications. The PTO cannot be disabled while the transmission is in Manual 3 (Overdrive position with Overdrive canceled), Manual 2, Manual 1. Refer to the "Body Builder's Layout Book" for recommended electrical installation. 124
