Valve bodies don't typically fail in normal use, unless they get clogged. So here are the questions:

Had you or your mechanic changed your transmission fluid at any time prior to that transmission valve body failure?

If so, do you think the fluid change could have contributed to that early failure? If not, do you think that changing the transmission fluid would have extended the life of the valve body?

Just wondering.
