Performance NAG1 Valve Body Modified by MMX

The MMX performance valve body was designed by using a fully operational, test NAG1 that monitored all clutch pressures, torque converter pressures, and torque converter lock up clutch pressures all with accurate analog gauges. This 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.
