found a sequential gearbox for gt 4, for anyone who doesn't know what this is its a manual transmission, but it eliminates the need for a clutch, there is no more H pattern you shift by either pushing the shifter up to shift up and down to shift down, check it out here too. http://auto.howstuffworks.com/sequential-gearbox.htm these are used in all high performance race cars, except like nascar
