did u buy an aftermarket slave or OEM? i had replaced my master and slave cylinder with aftermarket ones..still leaked.had to call honda for the real deal.
My suggestion is,if u say its not engaging or disingating, adjust the pedal and the hookup inside the car.where the pedal hooks up to the cylinder from the inside.maybe that can shorten or w/e it needs to be.
also to see if u need a clutch then shift into 5th gear and try to go..if it dosnt stall then you need a new one.
but try the pedal adjustment 1st!
