S74507HPK       Sonnax Performance Pack HP-4L60E-01
4L60E 94-UP & 4L65E. Sonnax Performance Pack HP-4L60E-01 combines innovative heavy duty/performance calibration for firmer shifts under load without sacrificing low-speed drivability. The precision components in this kit upgrade the 4L60-E for maximum performance and durability by recalibrating pressures, recalibrating shift accumulation and including improved parts for areas that commonly wear.
This kit is suitable for any heavy duty application and is a critical foundation for other upgrades when modifying the 4L60-E for high performance use.
