ROADMASTER TRANS

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.
