Honda/Acura 4-speed (3-shaft) and 5-speed transmissions often exhibit soft shifts and/or low line pressure rise. These concerns can be caused by incorrect or soft factory calibration of the clutch pressure control solenoids (CPCS), and further aggravated if there is line pressure leakage within the transmission. The PCM controls shift feel and overlap through CPCS A and B in conjunction with shift control solenoid C. Adjusting CPCS A and B can result in firmer shifts and increased line rise. Sonnax has developed pentagonal-shaped solenoid adjustment tool 88950-T to fit the recesses of solenoid adjuster screws.
