    Description

    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.
