9 – 13 SPEEDS


The Fuller Convertible manual transmission operates as a simple 9-speed transmission, and can then easily be converted to a 13-speed to increase vehicle versatility and resale value at trade-in time.

Turning your reliable 9-speed into a Fuller 13-speed transmission with an inexpensive conversion kit before trade-in will increase your truck’s worth by $3,000 or more over a similar truck equipped with a 10-speed. In addition, a truck equipped with a 13-speed sells about twice as fast as one equipped with a 10-speed transmission.
