Transmission Conversion Packages
An overdrive transmission is one of the most rewarding upgrades you can make to your Classic Car. In addition to the potential strength upgrade, the drop in engine RPM on the highway can make your car a joy to drive at speeds over 60 mph. All of this adds up to a much improved driving experience. The engine is less stressed on the highway, which means you’re less stressed, and the ride is quieter with lower engine speed and less fuel consumption. A higher numerical first gear makes it easier to pull away from a stop in everyday driving, and it quickens launch times in all types of racing.
