Part #: 1064844SS

The BD 6L80 Roadmaster transmission increases the reliability and longevity of stock or lightly modified trucks. Our remanufactured valve body has a new clutch select, and the TCC regulator valves eliminate sloppy shifting. Our deep sump oil pan will reduce heat and burnup of the clutches. A brand-new ProForce torque converter with a billet cover is included in every 6L80 Roadmaster Transmission Package.

Features:

  • New Billet ProForce Torque Converter which prevents notorious converter failure
  • Machined bellhousing and pump surface to eliminate wear and pressure loss
  • New Pressure Regulator valve to prevent low line pressure
  • New Clutch Select and TCC Regulator valve to eliminate sticky valves

  • New Cast Aluminum Transmission Oil Pan with an extra 2 quarts of fluid capacity
  • New Molded Pistons
