It can handle up to 575 horsepower and 500 ft-lbs of torque in non-supercharged, pump-gas applications. This transmission boasts a manual/automatic valve body, allowing drivers to select manual shifting for precise gear control or leave it in drive for fully automatic operation, resulting in quicker acceleration times. Internally, it features special clutches and bands for increased durability, new sprags and roller clutches for higher holding capacity, and an improved lubrication system to ensure optimal fluid flow to the planetaries and internals. The unit also comes with a chrome-plated transmission pan featuring an embossed TCI logo. Key specifications include a 9-inch tailshaft, a 2.52 first gear ratio, a 1.52 second gear ratio, and a 1.00 third gear ratio. It utilizes a non-lock-up converter type.
