A few questions...is the case aluminum? Borg Warner did make some replacement T10 type four speeds in the late '70s-early '80s that were cast iron. Is the input shaft 26 spline? Super T-10s were, and they also had the same size output shaft as a Turbo 400.

yah, it's aluminum and 26 spline

 

good move. that is what i installed after i blew up my saginaw.

 

I have the same transmission... 11.30.78 is the build date...but there are no grooves in the input shaft... What ratios did they come in?
