Do you have an overdrive switch for this transmission? Is it possible it is shifting out of overdrive?

Sounds like a synchro gear is bad.

had same problem and sometimes it took very high rpm s to get it to shift up. took it to a transmission shop they replaced 2 sensors in the transmission. $300 bucks. 2000 miles later it started doing it again..it ended up being the computer (ecm) and i never had that problem again.
