Shifting until it hits 5000 rpm on 2000 Volvo V70 XC

My V70 XC started shifting funny and now, it will shift until it hits 5000 rpm. We have changed the ETS and done everything we think is wrong with it, anyone out there with any suggestions?

Have you checked the diagnostic trouble codes in the engine and transmission computers? This is where I'd start.
