I know that th350/700r4/4l60/4l60e are 27 spline and that th400 and 4li0e are 32 spline. I have a t-case from a 90 or 91 4 speed manual trans dose any one know what the spline count is? I think on the old square bodies the manual and th400 were both 32 spline I do not know if the gmt400s continued this or not.
