5-speed Automatic Overdrive with Tow/Haul
• Optional on all Super Duty Pickups with gasoline or diesel engines
• Torque converter design maximizes low-speed torque output
• All-new more robust gear sets and a three-plate two-stage torque converter help
reduce turbine noise when the converter is locked
• Large fluid pump provides superior lubrication and cooling
• Pure electronic shift controls work with the Electronic Throttle Control of the engine to
optimize shifts and vehicle performance and responsiveness
• When hauling a heavy load or trailer, the Tow/Haul mode reduces gear hunting,
improves power delivery and even uses engine braking to help control vehicle speed
when descending hills
• Transmission can be equipped with power
takeoff port — must specify order code
62R (PTO obstructed by catalyst
placement on 5.4L and 6.8L engines)
6-speed Manual Overdrive
• Standard with all Super Duty
®
Pickup engines
• First five gears provide optimum
close-ratio performance
• Overdrive 6th gear reduces
engine rpm at highway speeds,
adding to vehicle fuel economy
and quiet operation
• Features a standard
transmission cooler
• Standard power takeoff (PTO)
port provided on the left-hand
side of transmission case
– PTO obstructed by catalyst
placement on 5.4L and
6.8L engines
NOTE: Some modification may be required to install the PTO unit on 6.8L vehicles.

Transmission Power Takeoff (PTO) Provision
• A power takeoff (PTO) provision is an added benefit for
customers with specific power needs
• Allows upfitters to supply power to hydraulically driven
accessories such as dump bodies, sprayers, pumps,
generators, etc.
• Option code 62R must be ordered to get a PTO gear
and port with the TorqShift 5-speed automatic transmission
• 6-speed manual overdrive transmission has a PTO gear
and port standard
• The optional upfitter switches may be used as PTO
control switch(es)
NOTES: Power takeoff (PTO) obstructed by catalyst placement on
5.4L- and 6.8L-equipped vehicles.
Stationary Elevated Idle Control (SEIC)
• Acts as the “throttle kicker,” when increased engine speed
is needed
• Consists of strategy embedded in the powertrain control
module (PCM) and a set of blunt-cut wires to command it
• Selling dealer will need to obtain a PTO controller or
switch from the aftermarket
NOTE: Option 66S, “Upfitter Switches,” one of which may be
used as a PTO switch.
• Engine speeds
– 910 to 2400 rpm (5.4L and 6.8L gasoline engines)
– 1200 to 2400 rpm (6.4L diesel engine)
• Automatically locks the torque converter
– Gives power to the PTO gear for the TorqShift automatic
transmission when the operator turns on the PTO switch
• Instructions to upfitters for completing the SEIC/PTO
