Glen, I guess you have checked your fluid level and condition, right? How about the linkage? Are you sure you are in D and not L2? After that, I would check the governor. On the THM-350, it's located under a round cover retained by a wire clip.(driver's side) If you can substitute a good governor, that would be best, otherwise look for a damaged drive gear or sticking valve and/or weights. Hope that helps.
I remember hearing somewhere that a 350 will not go in to high gear if the vacuum modulator is inoperative. Check the hose and tube leading down to it.
