Servo, GMC, 2nd Gear "Super Hold" Servo Assembly - GM 4L60, 4L60E, 4L65E, 4L70E
The Sonnax 4L60/4L60-E 2nd Gear Super Hold Servo has 18% more apply area than the Corvette servo (largest OEM) and maximizes holding power in 2nd gear with more positive 1-2 and 2-3 shifts. Dual seals on the 2nd gear piston and separator ensure positive band apply/release and eliminate cross leaks, which contribute to 2-4 band and 3-4 clutch failure. This servo is the perfect option when more holding power is desired without causing excessively harsh upshifts and downshifts. The included apply pin is longer than the longest OE pin, and has added seals to reduce leakage of 3rd and 4th gear oil pressure.
