Stage II Valve Body Information:
- Designed by using a fully operational, test NAG1 that monitored and recorded all clutch pressures, torque converter pressures, and torque converter lock up clutch pressures with a Race Pak.
- The Stage II modified valve body will increase the NAG1 shift pressures.
- The more aggressively the NAG1 is driven, the firmer the shift.
- The downshifts are firmer than stock also, but not to the point of being too harsh.
