Gen 4 liberty over rev

[aaseeby]

Hi people,
I have a Subaru liberty 04 auto I've noticed that my car changes gear on 4,000 To 5,000 rmp really late not only that it has lost a lot of power I've taken it to an auto electric but his computer couldn't find any errors It's starting to get really annoying and worrying me.

Please help!

I don't know much about the mechanicals of these cars but it sounds like your transmission might be low on fluid. Check that.
