Recently it feels like my 2001 Pontiac montana Wont shift into overdrive. When going over 55 mph it is running close to 3000 rpms. It is also making a whining sound that seems to be coming from underneath. If I shift it down to 3rd gear it doesnt really do much as far as the rpms but the whine goes away.

First check the trans. Fluid level. If OK then it may be the OD switch or torque convertor clutch.

I would take it to a reputable trans shop for a specific diagnosis.
