The Sonnax Performance Pack 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 calibrationFaster pressure increase and higher overall pressure for greater clutch/band holding powerThree ultra-reliable, patented, billet pinless accumulator pistonsUnique 1-2 accumulator spring combination for shifts with characterImproved high RPM pressureThird accumulator valve gets the 2-3 right the first time, every timeDurable parts target commonly worn areas and prevent future damage to the accumulators and separator plateThe only way to eliminate PWM function without over-pressurizing converters (optional)
