How concerned and what can be done about a very rusty Transmission Housing
in my '87 Westy?

No problems as of yet.  The rust really seems bad, though, kind a flaking
off chunks.  There is very minor body rust; usual seam and rear panel.  This
is a bus that is not a daily driver but has spent it's whole life in one
family, (Grandfather, Mother-in-law now us.) in Columbus, Ohio, Saginaw,
Michigan and now South Bend, Indiana.

I guess my question is:  Will the rust affect the Tranny?  Can it be
stopped?

Thanks!  Really enjoy reading all the posts each day!
