you from accidentally shifting into R
(Reverse) when you downshift from

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.
