Engines are
tough on transmissions. When increasing engine performance or towing
heavy loads, you need to consider the transmission. Typically, anything
beyond a computer chip or small boost in horsepower and torque requires
automatic transmission upgrades.
TnT Performance and Repair carries auxiliary transmissions designed to increase
torque and fuel economy. Sometimes these units are referred to as gear-splitters.
The systems are available in both underdrive and overdrive configurations,
depending upon your needs. If you need power to get things moving or
the engine lugs at low speed, you need an underdrive system. If you're
in search of lower RPM at highway speed, which results in better fuel
economy, you want to order an overdrive unit.
