I think one of the valves in the valve body on my S-10's 700R4 is
sticking a little. It doesn't make the 1-2 full throttle shift soon
enough and the engine seems to be hitting the rev limiter. Also, the
warmer the transmission the later the 1-2 shift occurs. Plus, if I
put the selector in "2" the 1-2 shift if always very late. It's time
to change the ATF and filter and while the pan is off anyway I was
wondering if I should take the valve body apart. Will I screw things
royally by attempting this or is it pretty straight forward?

If you have never taken a valve body out before and you aren't very
mechanically inclined, I would not attempt it. If you never worked on
anything hydraulic, then I think you are asking for problems. If you do take
in apart everything must be thoroughly cleaned and oiled back up when
assembling. The valve body usually has some little balls (like ball bearing
balls) used as check valves. These must be put back in and in the right
place.
