Automatics all came with 23 spline, manual transmission both NV4500 and NV5600 came with 29 spline setups. In the world of mega HP automatic transmissions, we upgrade to aftermarket 29 spline output shafts and swap the t-case input to match. Unfortunately, for the 47rh, there is not a 29 spline option so you are stuck with the 23 spline setup. That said, the 23 spline setup is pretty dang strong and most street trucks do fine with the 23 spline billet shafts.
