Under The Hood:

 Transmission Specifications for the International S1600

Transmission Type

The S1600 International was last manufactured in 1989. For the 1989 model year, the S1600 came with a manual transmission. This was the only transmission type used in the entire S-Series line over its decade-long history.

Transmission Gearing

A five-speed transmission was standard on the 1989 S1600, as for the entire decade the S1600 was in production.

Allison Transmissions

A truck-part replacement website, (see Resources), acts as a clearinghouse for past, current and future S1600 owners looking for replacement transmissions for their vehicles. One of the replacement transmission models available for the S1600 is made by Allison Transmission, a division of General Motors. The Allison transmission for the S1600 is model number AT545. Owners can download maintenance manuals regarding the AT545 and the other transmissions in the 500 Series at the Allison Transmission website (see Resources). This transmission features a first-gear ratio of 3.45:1, with a drive-gear ratio of 1:1.

Clark And Spicer Transmissions

The 1989 S1600 is also compatible with five-speed manual transmissions made by other companies, such as the 285V made by Clark and the Spicer CM-4054. The Clark 285V features a cast-iron case. Its first-gear ratio is 6.99:1, while its final-drive ratio is 1:1. The Spicer CM-4054 first-gear ratio is 7.88:1.

 Transmission Specifications on a 2006 Six-Speed Dodge Ram

Transmission Specifications

The 2006 Ram's NV5600 six-speed manual transmission used a synchronized-gear design. The transmission had the following gear ratios: 3.21 to 1 in first, 1.83 to 1 in second, 1.41 to 1 in third, 1 to 1 in fourth, 0.82 to 1 in fifth, 0.63 to 1 in sixth and 4.44 to 1 in reverse. The transmission had an overall top gear ratio of 2.72 to 1 with a 3.73-to-1 axle ratio, or 2.99 to 1 with a 4.1-to-1 axle ratio.

Ram Turbo Diesel and Transmission Weight Specifications

When paired with the 2006 Dodge Ram turbo-diesel engine, the NV5600 six-speed manual transmission had specific and recommended weight capacities. The turbo-diesel, six-cylinder engine with the standard NV5600 transmission had a gross vehicle weight rating of 9,000 lbs., a payload capacity of 1,960 lbs. and a base curb weight of 7,036 lbs. This combination had a gross curb weight rating of 20,000 lbs. and an estimated max trail rating of 12,800 lbs.

Ram V-8 Gasoline Engine and Transmission Weight Specifications

Dodge also offered the NV5600, six-speed manual transmission as an option for the 5.7-liter V-8 gasoline engine. This combination in the Dodge Ram achieved different weight capabilities and recommendations. The vehicle had a grand weight rating of 8,800 lbs., while the payload slightly increased over the turbo-diesel version to 2,540 lbs. It had a base curb weight of 6,262 lbs.,a gross curb weight rating of 15,000 lbs. and an estimated max trail of 8,600 lbs.

V-8 Engine Specifications

Dodge offered the 5.7-liter V-8 as the standard engine in its 1500 and 2500 Ram truck lines. This engine used a 90-degree, liquid-cooled design. It had a piston displacement of 5,654 cubic centimeters (cc), a bore of 3.92 inches, a stroke of 3.58 inches and a compression ratio of 9.6 to 1. It offered max power output of 345 horsepower at 5,400 revolutions per minute (rpm) and a peak torque output of 375 foot-lbs. at 4,200 rpm.

Turbo Diesel Engine Specifications

Dodge featured the six-cylinder, turbo-diesel engine as an option in its 2500 and 3500 Ram truck lines. The liquid-cooled in-line, six-cylinder engine featured a turbocharger with an intercooler. The pistons displaced 5,883 cc, and the engine had a bore of 4.02 inches, a stroke of 4.72 inches and a compression ratio of 17.2 to 1. It offered max power output of 325 foot-lbs. at 2,900 rpm and a peak torque capability of 610 foot-lbs. at 1,600 rpm.

 Transmission Specifications for a 2005 C6 Corvette


The C6 used two basic transmissions: the 4L65-E four-speed automatic, and the T56 six-speed manual. The 4L65-E was an evolution of the 700-4R from the 1980s, which itself was an evolution of the musclecar-era TH350 three-speed auto. In the Corvette, the 4L65-E used a 3.06- first, 1.63- second, 1.0- third, 0.70- fourth and 2.29-to-1 reverse gear feeding a 2.73-to-1 final drive. The regular six-speed manual used a 2.66- first, 1.78- second, 1.3- third, 1.0- fourth, 0.74- fifth, 0.50 sixth and 2.9-to-1 reverse, with a 3.42-to-1 final drive. GM also offered an electronic -- "manumatic," or "flappy paddle" -- version of the T56 that used a "skip-shift," first-to-fourth-gear function for a boost in fuel economy. For this reason, its first-though-third gear ratios are a little bit higher, to get them closer to the fourth gear's 1-to-1, and the final drive ratio is a little bit lower to "stretch" first gear's speed range into fourth gear's. It's ratios were 2.97- first, 2.07- second, 1.43- third, 1.0- fourth, 0.71- fifth, 0.57- sixth, and 3.28-to-1 reverse. The flappy-paddle box fed a 3.15-to-1 final drive gearset.

 Transmission Specifications for a Predator 90


The Polaris Predator 90 has a primary drive chain. The automatic, five-speed transmission is a continuously variable type (CVT), which aims to offer smooth driving, maximized performance and increased fuel economy. CVT transmissions are capable of moving in and out of countless numbers of gear ratios. Unlike standard automatic transmissions, CTV transmissions are not restricted to fixed gear amounts.


The Polaris Predator 90 has a single-cylinder internal combustion engine. The two-stroke engine has a displacement of 89 cc. The reed valve engine functions by limiting fluid flow to just one direction.

Brakes and Tires

The Polaris Predator 90 features drum brakes, also commonly known as expanding brakes, both in the front and back. The dimensions of the front tires are 19 X 7-8, while the rear tire dimensions are 18 X 9.5-8.


The Polaris Predator 90 can seat a maximum of one individual at a time. The height of the rider's seat is 27 inches. The weight of the ATV, which does not include the weight of any equipment, oil or fuel, is 262 lbs. The wheelbase of the Polaris Predator 90 is 38.5 inches. The ATV has a capacity of 1.3 gallons of fuel in total.
