Thanks John. I don't think there's any non OEM parts
involved with that transmission case etc. but will have a closer look.
I'd think that since the transmission
mount bracket and case are different metals,
once water/salt or ? + time are factored in, this is the cause?

I'll google up inter-granual corrosion.
