Allison 1000 Transmission

BD DIESEL PERFORMANCE

While the Allison is suitable for stock applications, we’ve 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 and once a clutch has slipped, the next time it will slip easier and easier.

 
Highlights of our modifications:
 
BD rigid aluminum heavy duty transmission pan
   • Adds 3.5qt extra oil capacity
   • Reduces case flex
   • Reduces internal oil leakage
   • Heat-dissipating fins keep temperature down
   • Magnetic drain plug
New convertor lock up valve to boost lock-up pressures
Updated lube
Updated regulator
Updated pressure release spring
20% more friction surface
High energy clutch material
Added extra frictions
Modified power pistons
Modified hydraulics
New return springs
Increased main line oil pressure
Modified separator plate for short crisp shifts
New A & B trim valves, springs and solenoids
 
WARRANTY: 36-month / 150,000 mile limited exchange warranty on non-competitive, racing or sled-pulling applications. Some conditions apply - See warranty statement for further details.
