Our industry leading equipment, staff, and years of knowledge in the pulling and racing industry ensure that you are getting the best performance built Allison transmission on the market to date!DHD's Dirty-Alli Allison transmissions are designed to hold 750hp as configured @ $5999.00. For those seeking to hold more power we recommend transitioning to billet internals and a extreme clutch converter. Replacing your OE cast internals with billet components provides piece of mind and decreases the chances of catastrophic failures during shock loads.We take pride in our work! Transmissions are assembled in a clean and controlled environment. Every piece is hot tanked, ultra sonic cleaned, and personally inspected for even the slightest flaws. A series of highly specific measurements, function and piston apply tests are performed before the transmission leaves the stand.Dirty Hooker Diesel is THE source for Performance Built Allison Transmissions!Build Highlights:Clutch Pack Setup and MachiningHigh Performance FrictionsPrecision Gaskets and SealsAll New Factory Allison Torrington BearingsNew Molded Clutch Apply PistonsUpgraded Sleeved C2 Hub w/ Machined P1 Sun GearNew Bushings ThroughoutTurbo-Tony Valve Body ReworkUpgraded Line Pressure ControlsDHD Billet Stator Torque ConverterGenuine Allison Stamped Deep Transmission PanGenuine Allison Spin-on and Deep Pan FilterNew Pressure Switch & WiringNew SolenoidsCore Charge and Freight ExtraCore:DHD does require cores on all Transmissions and Converters.
