I have been wanting to get a new revmax converter for a while now, but I have a few questions first. How would a guy tell if his valve body already has a shift kit in it. My truck shifts way faster and more firm than any of my friends trucks, which is my theory on why I broke my second gear band strut. If the valve body was stock, i have heard that there is a way to turn the line pressure up on them. Is this true? My last question is can I upgrade the converter to a single disk lower stall with my stock valve body. Any advise would be appreciated. I already have the upgraded gov pres sensor and transducer.
