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.
Large displacement torque master
engine, smooth shifting Allison
transmission with auto downshifts when
braking down hills.
Normally flawless Allison transmission
does have a few bugs. Oil consumption
is a little high but not a problem.
