Since its introduction in 1969 with the 428 SCJ, the R code servo has remained the trick piece for C6 builders needing additional band apply force. Sonnax R code servo kit K36528R for C6 (mid 68-later) units features a no-leak pin which uses one O-ring and one PTFE ring to eliminate back pressure and leakage due to worn case bores. A replacement seal kit K36528R-SK also is available.
- More than 9 square inches of apply surface for more band apply force
- No-leak servo pin design allows the servo piston to be used in worn bores
- Two selective return springs allow for tuning of shift quality
