The Best Diesel Transmission Made Even Better!

The introduction of the Allison 1000 transmission to the diesel truck market restored confidence in consumers that an automatic transmission can indeed handle the demands of exhaust braking and diesel engine torque. But while the Allison is suitable for stock applications, weve found that it does have its limitations particularly when flywheel horsepower exceeds 370 horsepower. Thats when the stock clutch packs can begin to slip, putting the computer in the dreaded limp home mode. Several Modifications have been made to the Allison to suit the demands of highperformance and heavy duty usage.  20% more friction material has been added than stock, and an increase in main line oil pressure to increase clamping force on the clutch packs. These revisions along with modified trim solenoids, pump, pressure regulator, and oil circuitry result in a transmission that can now handle 500 flywheel horsepower under heavily loaded conditions.   If youve modified, or plan to modify your Duramax, the first step should be a BD Allison transmission.
