You’ve got the suspension dialed in. You’ve got the power under the hood. Now you need to transfer that power to the rear wheels. One of the keys of success at the race track is keeping the car in it’s power range for as long as possible. Running low gears in the rear axle will help do this but can ruin your fuel mileage. Modern automatics require changing computer programs to control shifting patterns and somewhat limit your control of shift points. Thanks to the engineers at Tremec and GM, now you can have the best of all worlds.
The Tremec T-56 manual transmission puts you in control of gear changes allowing you to cater your driving style to each individual racing experience. Heavy duty internals can handle up 700 ft lbs of torque making it perfect for higher output engines. Splitting gear changes over 6 speeds allows your motor to stay within it’s power band for longer periods of time. With the double overdrive 5th and 6th gears it tames the most aggressive rear axle gears to run calmly down the freeway while increasing your fuel economy. For strength and ability you can’t beat a T-56 Magnum.
