The Black Edition features all the components of our Level 3 transmission with the following upgrades for added strength and durability. Nothing but the best!!!
Upgraded five (5) pinion planetaries
4L78 Input Drum: This is a major upgrade of the input drum assembly on these units, improving rigidity and cooling over the stock input drum. With a 6061 threaded billet endcap it further helps shed heat from the 3-4 clutch better than steel. This billet endcap also strengthens the drum itself.
Molded seal steel pistons
Alto High Energy carbon composite forward friction plates.
A set of Alto High Energy clutches with our new proprietary drilled steel plates for high-impact-durability and added cooling on the 2-3 shift.
Borg Warner 29 Element Dual Cage Sprag assembly, the strongest available.
THE BEAST SHELL To eliminate stripping of the splines and breakage common in the factory sun shell; which causes reverse, second and fourth gears not to work; we install the Beast Shell. The shell is also balanced to lower drive train vibration.
Machined OEM reverse Input drum to accommodate the ultra-wide carbon band.
Ultra wide carbon composite 2-4 performance band with reinforced pin area to prevent tear through. This band will take the abuse and the heat.
Our Performance Billet Servo is used for maximum second gear hold. (It also limits 3rd gear 3-4 clutch accumulation to aid in the 3-4 clutch apply.)
Performance Billet Overdrive Servo Used with the wide band to withstand wide-open-throttle, while in overdrive, if your PCM is set up to allow it. Anodized red with PerformaBuilt logo laser etched.
A Thirteen (13) vane pump with hardened rings and a full-time lube modification which assures maximum planetary life and cooling.
Max line set at approximately 220 PSI.
PerformaBuilt custom shift kit: A compilation of what we consider to be the best of several known kits; and some unique modifications of our own.
Deep Chrome Pan or Optional cast aluminum pan (Additional charge for cast aluminum pan)
