Hey Richard,

Thanks for the info.  Is my face red!  Come to think of it, I did put
synthetic Redline 75-90 gear oil in; not MTL.  Since I'm in NC, I recall the
choice for the tranny being MTL or a little heavier weight Redline.  I went
with the heavier to avoid any problems since it rarely gets under 30 degrees
here in winter.

Will attempt to install the seals myself tho.  Any idea if there's a problem
with the original seals such that Mazda will pay for mine or if there's a
recall?  (Yeah, I wish!)

Thanks again.
