INSTALLATION INSTRUCTIONS INCLUDED
- PROUDLY MADE IN THE USA
- 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. For the ultimate servo combination in your 4L60/4L60-E, Sonnax recommends using the Sonnax 4th gear super hold servo 77767K with the Sonnax 2nd gear super hold servo kit 77911-03K.
