Suncoast GMAX TRANS 4X 4WD2003 GM Duramax LB7 (4WD)The Allison 1000 transmission is more than suitable for stock applications, but it does have limitations. Once power exceeds 90-110 horsepower over stock the OEM clutch pacs begin to slip. Once slippage occurs, the transmission control module overrides the Allison and puts it into fail safe mode, often referred to as "Limp Mode." Once the Allison reaches this state it begins to limp easier and easier. Luckily, SunCoast has the solution. SunCoast's Allison 1000 series transmissions are designed and engineered to be the most dependable, heavy duty transmission option on the market. Its Allison transmissions are proven to be more durable and dependable in any situation: street, sled pull- ing, towing or drag racing (transmission options may vary). Built with the best possible Allison parts on the market, these units can hold in excess of 1900 RWHP (with correct supporting hard parts).Standard Features:
