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, we've found that it does have its limitations, particularly when flywheel horsepower exceeds 370 horsepower. That is when the stock clutch packs can begin to slip, putting the computer in the dreaded "limp home" mode.

At BD, we make several modifications to the 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.

  • Increase the durability of your drivetrain
  • Revised oil circuits
  • Roller bearings throughout
  • Extra clutches and stronger internals
  • Handles up to 300% more power and torque than the stock transmission
  • Comes with BD's heavy Duty transmission pan
  • Not warranted for Race or Sled Pull use

Reviews

  • How much power can it hold

    Zach | 2/8/2020

    Its really not about how much power it can hold as much as what will you be doing with the truck?  This is not a competition application trans, IE no sled pulling or drag racing.  It is however a transmission that can handle a daily driver/ tow rig with a moderate power increase better than your stock trans.  To put a number on it though, with a normal driving conditions, 450-500HP

  • I bought a transmission from you in Feb. 2012 and lately I have noticed when I take it out of park and put it in reverse or drive, it takes a minutes or so before it will pull. I have 56k miles on the trans. What could be the problem.

    First thing that we need to do is check trans fluid.  Is the fluid level correct.  That is too long before the truck is in motion and you could be doing damage to the trans.  Give us a call 866 737 4966
