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

235 lb-ft of torque @ 4,000 rpm
