T36165 C6 SHIFT KIT (1965-1968)

This kit will convert most 1977-on gas valve bodies to work on a diesel (a .410 or .437 boost valve must be used when converting a gas vale body for diesel use. Many gas vale bodies have this size). Raises overall line pressure. Calibration for a higher speed manual low. Crisp shift performance and more durability.
