The Pro Series improves the performance of your Duramax with even greater holding capacity with an 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.
"We don't play horsepower rating games with our MAximum Transmissions; we just build high-quality transmissions with high-quality parts that hold up to common abuse!" Exclaims Eric Merchant Automotive Founder.
