Description: 4L60-E, 4L65-E, 4L70-E Performance Pack Part No. HP-4L60E-01 Fits '94-later units. The Sonnax Performance Pack for GM 4L60-E, 4L65-E and 4L70-E transmissions is a must-have for any heavy-duty vehicle and the very best foundation for high-performance racing. All components work together to carefully tune line pressure, accumulator pressure and shift calibration. It’s the ultimate way to get an impressive transmission that responds to throttle and increased load with quick, firm shifts. Consistent, firmer shifts under load without sacrificing low-speed drivability or guessing on calibration Faster pressure increase and higher overall pressure for greater clutch/band holding power Three ultra-reliable, patented, billet pinless accumulator pistons Unique 1-2 accumulator spring combination for shifts with character Improved high RPM pressure Third accumulator valve gets the 2-3 right the first time, every time Durable parts target commonly worn areas and prevent future damage to the accumulators and separator plate The only way to eliminate PWM function without over-pressurizing converters (optional) Contents 1-2 Accumulator Valve Shim TCC Pressure Limiter Valve & Spring Optional, eliminates PWM/EC3 function Boost Valve with O-Ring .490" Elevated Pressure Regulator Spring High RPM Pump Slide Spring Spacer 4th Servo Return Spring Servo Cushion Spring Servo Piston D-Ring Kit 3-4 Accumulator Piston Kit 3-4 Accumulator Spring Servo Release Check Valve Forward Accumulator Kit Checkballs (8) Separator Plate Plugs Not Shown Twist Drills Not Shown 1-2 Pinless Accumulator Piston Kit 1-2 Accumulator Inner Spring 1-2 Accumulator Outer Spring 1-2 Accumulator Waved Spring
