I bought a 727 trans from a co-worker which he said was modified by Mancinni Racing years ago. I open it up and find the entire parking gear and governor body has been removed. This includes all rods, clips, etc. Was this common practice to remove in a performance/race trans buildup? This trans was in a street driven car. Second question, can you modify a stock valve body to work as a reverse valve body? It still has a stock plate between the valve body halves. The guy swears it is a reverse pattern shift. Any way to check this out on the bench?
