Transmission Upgrade Buyer’s Guide – BD Diesel, Banks Power, and Bully Dog

Transmissions

• 
  BD Diesel Performance Transmission

  The stock transmission and torque converter were designed to handle the output of the stock engine, but not much more. Increase the durability of your drivetrain with a BD Diesel transmission and torque converter. BD transmissions incorporate revised oil circuits, extra clutches, and stronger internals to handle up to 300% more power and torque than the stock transmission. All BD Diesel transmissions come with their heavy-duty transmission pan, and most Dodge and Ford applications come bundled with their Full Flow Transmission Filter Kit for added protection and cooling.

  • Increased Power Handling Capability

Torque Converters

• 
  Banks Billet Torque Converter

  With its multi-disc lockup clutch assembly and improved forged-steel billet housing that maintains solid contact without flexing, the new Banks Billet Torque Converter provides far greater torque capacity than stock (1100 lb-ft vs. 740 lb-ft). And because the lockup clutch is slip-resistant, transmission fluid temperatures stay cooler and transmission life is prolonged. From its single-piece billet housing CNC-machined from forged steel to the furnace-brazed turbine and impeller to the furnace-brazed and hardened turbine hub to the hardened pump drive made of 4130 chrome-moly steel to withstand massive torque, the Banks Billet Torque Converter is built for precision, performance and long-lasting durability.

• 
  BD Diesel Triple Torque Force Converter

  With Diesel engine high torque performance and high-load situations, the torque converter must multiply the torque at low engine RPM to get the truck moving and then the lock up clutch must hold on in peak demand. BD Diesel TorqForce torque converters were specifically designed to handle the kind of punishment you dish out.

  • Billet Steel Cover
  • Single and Triple Piston Lock Up Clutches Available
  • Furnace-Brazed Fins
  • Reduced Coupling Speed
  • Enhanced Low-Speed Drivability
  • Improved Fuel Economy

Transmission Shafts

• 
  BD Diesel Billet Shafts

  Increase transmission durability with either stock or Billet input, output, and intermediate shafts and hubs. Billet shafts, which are rated up to 300M and 300 Maraging, are designed to take the shock from high horsepower and heavy loads, which is highly recommended when using our Triple Torque Force converter or for any truck making over 500RWHP. Replacement stock shafts and hubs are also available for the less aggressive trucks.
