Re: 75 GMC motirhome TH400 rebuild ?

there is a th375 model factory with 27 spline shaft . . . not near as common to find .

as others said rebuild the one from your motor home for the best results in the end .

a th475 the motor home spec one there is a few major things in there that make them beefy for there heavy duty use .
