ROLLERIZED FORWARD DRUM.Over time the factory metal thrust washers wear and as a result increase operating clearances and send debris through the transmission.All metal thrust washers in the transmission are replaced with high capacity low drag needle bearing assemblies.This is a time consuming process but definately beneficial for a performance transmission build.Internal components are machined in a lathe to create pockets for the bearings to locate in,as well as generate proper clearances.These bearings also reduce internal friction.This results in lower thrust surface operating temperature,and reduced horsepower loss. CALIBRATION UPGRADES EXCLUSIVE CK PERFORMANCE SEPERATOR PLATE DIRECT CLUTCH CORRECTION PACKAGE RECALIBRATED VALVE BODY AND GOVERNOR Over 20 years of research and development have resulted in the ultimate combination of performance and component durability.The main problem with this transmission at high power levels is the direct clutch.Our custom seperator plate removes flow restrictions that cause 2/3 upshift delay and friction element slip.Our revolutionary "3/2 Control Valve Delete" removes the infinitely variable orificing of 3rd accumulator oil to the servo release from the hydraulic system,and uses a single orifice.This is the real correction for direct clutch failure.Custom automatic shift valve body and governor combinations can give you the wide open throttle upshifts your vehicle needs.Calibrations can be made to allow wide open throttle shift points anywhere between 5000 and 6500 rpm's,without shift timing complaints at light or part throttle.
