for more info on the sd33t . Mine has a tf727 that has the jeep NP/NV 23 spline output shaft ,( its going into a comanche) it is an industrial motor , designed to run forever , not a huge power house from the factory , but parts are still plenty . in auz and nz there are loads of them in nissan patrols . and for those who think you cant make power with these lookie here
the ones like i have ( from the military) are heavy duty versions just without a turbo .
