350Z Built Automatic Transmission


Speed Force Racing can take your stock automatic transmission that is barely capable of withstanding 400WHP and turn into an incredible transmission that can withstand 750WHP!The secret is the use of 25% more aftermarket clutch packs.We determined that more is better and then we decided to use the highest quality clutch packs that are available on the market.The result is a transmission that can handle 80% more power the the stock transmission and still maintain the drivability that makes the automatic desirable.Besides building the transmissions internals we also modify the valvebody to operate at a slightly higher line pressure which results in quicker shifts.
