MAXIMUM WORK SERIES
If you depend on your truck to be there when it counts, the Maximum Work Series Transmission is for you! Designed to optimize the potential of the Allison transmission even with additional power, it still maintains the smoothness of a stock transmission. If you’re looking for everyday use with increased holding capacity when it counts the most, look no further than the Maximum Work Series Transmission.
MAXIMUM PRO SERIES
Building off the proven reliability of the Work Series, the Maximum Pro Series provides even greater holding capacity with additional clutch apply area, heavy duty friction material, and additional hydraulic pressure. If your engine is modified above stock, or aftermarket components (proper tuning and gearing required), then the Maximum Pro Series is for you.
