Eaton® Manual Transmissions
General Information
A Freightliner M2 Plus vehicle may be equipped with
an Eaton manual transmission. Vehicles with Eaton
manual transmissions have clutch brakes and a
hydraulic clutch actuation system.
The transmission shift pattern is printed on a decal
attached to the driver-side sun visor or to the dash
below the center dash panel. The shift pattern may
also be printed on the shift knob.

Transmission Operation Tips
Follow these important operation principles:
•
For all conditions, use the highest gear that is
still low enough to start the vehicle moving with
the engine at or near idle speed, and without
slipping the clutch excessively.
When operating on-highway with no load or
under ideal conditions, use 1st gear to start the
vehicle moving forward.
When operating off-road or under adverse
conditions, use LOW gear to start the vehicle
moving forward.
•
Use the clutch brake to stop gear rotation
when shifting into LOW or reverse while the
vehicle is stationary. The clutch brake is
actuated by depressing the clutch pedal all the
way to the floor.
•
Partially disengage the clutch to break engine
torque during normal gear shifts.
•
Double-clutch between all upshifts and
downshifts that require movement of the shift
knob. Splitting of gears does not require
movement of the shift knob.
•
Never push the range-preselection lever down
into low range while operating in high range,
except when downshifting from 5th gear to 4th
gear.
•
Do not shift from high range to low range at
high vehicle speeds.
•
Never make a range shift or a splitter shift
while the vehicle is in reverse.
•
Never move the range-preselection lever with
the transmission in neutral while the vehicle is
moving.
•
Skip ratios while shifting only when operating
conditions permit, depending on the load,
grade, and road speed.
•
Never coast with the transmission in neutral.
