gear) positions will demonstrate that the transmission
is able to shift into and out of Overdrive. For vehicles
with 5.7L engines (which have two Overdrive gears),
the transmission may not shift into the top Overdrive
gear (normal fifth gear) until the transmission fluid
and engine coolant are warm.
• If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.

FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I Operating Instructions/
Precautions – If Equipped
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which provides convenient full-time four-
wheel drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE: The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to "Off-Road Driving Tips" in "Starting and Oper-
ating" for further information.
