NV5600 Manual Transmission, G56 Manual Transmission, and 48RE Automatic Transmission Performance Upgrades.

  • Heavy-Duty Torque Converters: Upgraded torque converters built to withstand the higher torque loads of a modified engine, reducing slippage and improving acceleration.
  • Performance Valve Bodies: Upgraded valve bodies that optimize gear changes and improve transmission responsiveness under increased power demands.
  • Transmission Cooler Upgrades: Enhanced transmission coolers that improve heat dissipation and maintain optimal transmission fluid temperatures.
  • Heavy-Duty Transmission Rebuild Kits: For experienced mechanics or performance shops, these kits offer the most significant upgrade, rebuilding the transmission with stronger components to handle significant power increases.

Why Upgrade Your Transmission?

The stock transmission in your Cummins might not be able to handle the additional power and torque from engine modifications. Upgrading your transmission helps ensure:

  • Smooth and Reliable Shifting: Maintains smooth gear changes and prevents transmission damage from excessive power.
  • Improved Power Delivery: Allows the engine's full power potential to be transferred to the wheels efficiently.
  • Extended Transmission Lifespan: Upgraded components can handle higher loads, potentially extending the transmission's lifespan.
