Nice, yet unusual find. About the D34 code, I think that means “light duty automatic”, right? Does that car not have a 727? Is there such a thing as a light duty 727? I know they made motor home 727’s that had beefier internals and some for Hemi cars. What’s the code for a 904? I would think that a 904 would be light duty, a 727 standard duty, or heavy duty. Just some pondering.
