The governor valve is probably sticking.
It`s fairly easy to pull the extension housing and clean the governor housing and valve. As the fluid gets older, junk builds up in the gov housing causing the gov valve to stick, not allowing the trans to drop back into a lower gear. A stuck shift valve in the valve body could also do it.
If you don`t want to dig into it, change the fluid and filter, and add 1 bottle of lubeguard. Most transmission shops carry it, I know our local parts stores do also. I`m really fussy about any additive, most of the overhaul in a can stuff is really acidic, and it might soften seals in the short term, but end up doing more damage than good.. Also the zinc in them tarnishes the heck out of anything metal..
After the fluid change he might have to put some miles on it to get her to drop again. If that don`t work, then go after the governor itself. Goodluck BW
