Dodge 2009 Ram Diesel Owner's Manual Supplement page 51

NOTE:
• During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel
engine to resonate heavily for a moment during engine
shut off. When the engine is connected to a manual
transmission, this resonance causes load gear rattle
from the transmission. This is commonly referred to as
"shut down rattle." The manufacturer recommends
performing engine shut down with the clutch pedal
pushed to the floor (clutch disengaged). When engine
shut down is performed in this manner the rattle is
reduced (not eliminated).
• Refer to the following chart for proper engine
shutdown.
