You might be a bit frustrated by the screw not being screwable but in the big scheme of things it might not be such a bad thing. You can check the amount of travel in the band if you remove the valve body =>

See post #36 in the thread I linked earlier

This can be done with the transmission in-situ

However, if you remove the valve body to do this "the wise" say it is best to put on a new gasket to make sure you don't get random leaks...
