TOWING
TECHNICALLY , IT'S A 1/2-TON . BUT
THERE'S MORE TO IT THAN THAT .
Tundra's available 10,400-lb. towing capability
by a frame design we call TripleTech.
Tundra uses a specifi c structure for each of the three frame sections. TripleTech
the ideal tow vehicle, with strength and durability built in.

6-SPEED AUTOMATICS
Tundra's available 6-speed automatics
give it a wide overall gear range. That
translates into a brisk acceleration
at low- and mid-range rpm. And fi rst
gear's ratio is extremely low — ideal
for serious towing. There's also no
need to choose from a variety of rear
axles: Tundra's available 4.300 rear
end 2 works seamlessly with the wide
transmission gear range to optimize
performance.
TRANSMISSION COOLING SYSTEM
Our available 5.7L V8/6-speed
automatic transmission powertrain
comes with an Automatic
Transmission Fluid (ATF) Warmer,
improving performance on cold start-
ups. An available Tow Package also
comes with supplemental coolers for
the ATF, the engine oil and the power
steering fl uid. It's all in an effort to
cut heat buildup caused by added
demands of towing.
DRIVE SHAFT
Regular Cab Long Bed, Double Cab and
CrewMax models use a 2-piece drive
shaft: The front section is steel, the rear
section aluminum. Using aluminum
cuts Tundra's unsprung weight and
reduces rotational mass for enhanced
acceleration. It also cuts down on noise,
vibration and harshness.
TRAPEZOIDAL FRAME SECTION
When you think of suspension, you
probably think about up-and-down
movement. But our engineers also
thought about lateral stability. The
trapezoidal rear section of Tundra's
TripleTech TM frame allows the rear
leaf springs to be positioned toe-out,
where the front is mounted farther
out than the rear. The result: The
trapezoidal rear frame section and
the toe-out rear leaf springs help
deliver superior lateral control when
cornering and especially while towing
heavy loads.
