It would be helpful to have a bit more information. When you say a "tendency not to shift" does that mean it never leaves first or will it eventually shift and if so, will it go all the way to direct drive? Does it consistently fail or just occasionally. If eventually something happens, then a couple of possibilities besides the sticking valve also come to mind but would still need more information. At any rate, I'd go with Randy's suggestion and at least do the fluid change and see if anything changes before going further.
