2-44. OPERATING IN MUD
a. Before Operation.
(1)
Before operating in mud, place transfer case shift lever in H/L (high/lock
range) and transmission shift lever in
(overdrive).
(2)
Refer to para. 2-40 for techniques that can be used when operating on
unusual terrain.
b. During Operation.
CAUTION
• Do not repeatedly shift transmission or overspeed the engine
during operation in deep mud. Damage to drivetrain may result.
• Use wrecker or a second vehicle equipped with winch to recover
vehicles mired in deep mud. Do not attempt to rock vehicles out of
deep mud with quick transmission shift changes. Damage to
transmission will occur.
NOTE
If additional power is needed to extract vehicle when mired in mud,
place transmission in 1 (first) and transfer case in L (low range). After
vehicle is extracted from mired condition, immediately return transfer
case to H/L (high/lock range) position and transmission to
(overdrive).
Skidding and sudden loss of steering control are operating problems in mud.
When rear end skidding occurs, immediately turn wheel in direction of skid until
control has been regained.

Do not rely on service brakes until they dry out. Keep applying brakes
until uneven braking ceases. Failure to do this may cause damage to
vehicle and injury or death to personnel.
