I just want to add to what I have said, if you want to replace a torque converter system you must remember that if your old system was asymmetrical then a symmetrical system will not swap out on symmetrical systems the non-movable pulley faces must be opposite each other. That puts the movable faces of the two clutches to where they work together as the drive pulley forces the belt higher in the v then the driven clutch is forced to open and allow the belt to reduce the diameter of the spinning belt. And as the torque load on the rear wheel increases the torque load is sensed by the drive clutch and it automatically changes to ratio the maintain engine rpm and up the hill you go LOL School is now over.
