Most automatic transmissions are designed for shifting smoothness and comfort. Also, most drivers feel that a soft or smooth shift is easier on the transmission. Unfortunately, the opposite is true.

Transmission designers achieve a soft or smooth shift by extending the duration of every shift. While this makes shifting more comfortable, power decreases during the extended shift and all friction surfaces receive excessive wear. The end result is a transmission that does not last as long as it should.

Transmission shift kits have been designed to overcome transmission design deficiencies by reprogramming each shift to be faster and more efficient. The result is a more durable transmission with greater performance and efficiency.
