The following parts are aluminum. Direct clutch carrier, front drum, rear drum. The sun shell has been wacked (1 lb removed), the rear pump is gone, the governor is gone, The parking pawl gear is cut down to .250". And Lee just for you, the output shaft was turned down to remove about .125" along with the speedo gear drive. It had an aluminum rear annulus gear in it, but the teeth were taking a beating. We'll see how it works this weekend.
