Coasting

WARNING!
Do not coast with the transmission
in neutral or with the clutch pedal
depressed—it is a dangerous prac-
tice. Coasting in neutral may result
in damage to your drivetrain when
you try to re-engage the transmis-
sion. You could lose control of the
vehicle which can lead to an acci-
dent involving death or personal in-
jury.
Do not coast with the transmission
in neutral or with the clutch pedal
depressed. Besides being illegal and
dangerous, coasting is also expensive.
It causes premature failure or damage
to the clutch and transmission and
overloads the brake system.
Y53-6060-1C1
Coasting with the transmission
in neutral also prevents proper
transmission component lubrication.
During coasting the transmission is
driven by the rear wheels, and the
countershaft gear (which lubricates
the transmission components by oil
splash) will only be turning at idle
speed.
