BD Diesel Transmission Kit | 2007-2010 6.6L GM Duramax LMM Allison 1000 2wd
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, BD Diesel has found that it does have its limitations — particularly when flywheel horsepower exceeds 370 horsepower. That's when the stock clutch packs can begin to slip, putting the computer in the dreaded “limp home" mode.
BD Diesel has made several modifications to the 2wd 2007-2010 GM Duramax LMM Allison to suit the demands of high-performance and heavy-duty usage. We add 20% more friction material than stock, and increase main line oil pressure to increase clamping force on the clutch packs. If you've modified or plan to modify your Duramax the first step should be a BD Diesel transmission.
