THE DODGE 3.7-LITER MAGNUM
®
V6.
The standard engine for the 1500 4x2 confi gurations of the longest-lasting,* most durable
†
line of full-size
pickups comes with impeccable credentials. With its proven history of reliability and longevity, the
3.7-liter Magnum V6 lets you step up to the jobs that simply don’t require the superlative torque of the
6.7-liter Cummins, or the massive power of the 5.7-liter HEMI V8. Obviously, when compared to its
stablemates, there are valuable trade-offs: while you’re saving on power output, you’re also enjoying
effi ciencies

in fuel costs from the lower displacement numbers. Output is still impressive and up for
the job: 215 horsepower and 235 lb-ft of torque at your disposal, with payload maxing out at 1,830
lb;

maximum towing is 3,800 lb.

DRIVING THE OTHER HALF OF THE DRIVETRAIN: THE RAM TRANSMISSIONS.
1 THE DODGE 6-SPEED 68RFE AUTOMATIC TRANSMISSION
For the growing family of Dodge Ram Heavy Duty work trucks, the 68RFE 6-speed automatic transmission
is available. Optional for Ram Heavy Duty 2500 and 3500 pickups (in both single- and dual-rear-wheel
confi gurations) equipped with the available Cummins
®
6.7-liter Turbo Diesel, is the Dodge 68RFE 6-speed automatic.
The combination of Cummins and the Dodge 6-speed automatic provides benefi ts measured by the best criteria for
business today: strength, stamina, and reliability. Another advantage that Dodge offers with Cummins and this
transmission? The 6-speed with Electronic Range Select works in concert with the factory-installed engine exhaust
brake, further optimizing control of the vehicle, enabling the driver to control rpm and speed — especially valuable
when decelerating downhill.
2 THE 6-SPEED MANUAL TRANSMISSION
This transmission is built for heavy-duty work, and is the standard transmission for all Ram Heavy Duty
models. A principle feature is the ultralow fi rst gear ratio — as low as 6.29:1 — which is ideal for heavier
hauling requirements.
3 THE 5-SPEED 545RFE AUTOMATIC TRANSMISSION
One of the most popular choices in combination with the 5.7-liter HEMI
®
V8 is the 545RFE — the available and
long-proven 5-speed automatic transmission. Consistent with the Dodge objective of taking technology a step
beyond the expected, the 545RFE features a specialized fi fth gear — available as an additional overdrive ratio
to help provide increased fuel economy and reduced engine noise at highway speeds. (The fi fth gear ratio
is 0.67:1 — a 16 percent reduction in engine rpm relative to the fourth gear 0.75:1 ratio.)
It’s everything a horsepower and torque chart
should be: a long, virtually fl at torque line that
signifi es reliable and competent towing capability,
with a steady horsepower line indicating comfortable
cruising and responsive acceleration at takeoff.
215 horsepower @ 5,200 rpm
