Transmission valve body question...

Transmission valve body question...
My 99 blazer has 140,000 miles. I am noticing after running on the highway for an hour or two that when I get off the exit and start from a light or stop sign that I'm gettting a hard 1-2 shift. It doesn't do it all the time, mainly after having been at highway speeds.
A tranny shop where I have had work done before with good results, said it's most likely the valve body and needs to be fixed. About $400 to do it. But, if they drop the pan and see shavings, plastic parts, and overall "crap" in their then I'm looking at a rebuild.
What do you guys think at this mileage, could it just be the valve rebuild or am I looking at whole rebuild?
One other thing related...I occasionally get a slight shudder when taking off from a stop. Doesn't feel like the torque converter, the Ujoints are tight, motor and tranny mounts are good.
Any help appreciated.

I just had my valve body rebuilt and a Transgo shift improver/P1870 fix kit installed as well as both shift solenoids A and B replaced at 145,000 miles. No problems since (other than the shift kit doesn't like it when i baby the truck which i do most of the time)

It could just be the valve body. I had to do mine but I have less miles than you. $400 is a good price too. I did my own and it cost me nearly $300 just for the rebuilt valve body and tranny fluid.
