Great truck
By Jerrygee on


2003 Chevrolet Silverado 2500HD 4dr Extended Cab LT 4WD LB (6.0L 8cyl 4A)


Almost 500 cubic inches and the 5
speed Allison automatic transmission
makes for plenty of towing and hill
climbing power. Gas mileage is better
then what you would expect at 12+ MPG
on the highway when not towing, but
watch the mileage plummet when pulling
a load. Reliability has been perfect
at 11 months and 17,000+ miles of
ownership. Interior is spacious,
rattle free and quite. Ride is a
little harsh, but don’t forget, it is
a truck! My only complaint is the
Allison transmission does “spaz out”
every now and then and gives me
strange downshifts when coming to a
stop or “clunks” when first going into
drive in the morning.

Best Features

Large displacement torque master engine, smooth shifting Allison transmission with auto downshifts when braking down hills.

Worst Features

Normally flawless Allison transmission does have a few bugs. Oil consumption is a little high but not a problem.
