revving noise when shifting gears

[2.8broncoII]

i have a 3.0 5 speed 2000 ranger. when i try and shift from 1-2 or 2-3 it mskes me push hard to get it into gear and makes a noise like something is revving up. this only happens when i get the rpm's high in 1st or 2nd gear and go to shift to the next. any ideas?

when was the last time you checked your tranny fluid?

just checked it and its a ok, that was the first place i looked. The tranny just started doing this and its annoying.

Sounds like the synchro's trying to spin the gear up to speed.

I can hear this very faintly in mine when I try to get it into 1st while rolling too fast, I have to have the radio off to hear it though.
