Help 04 lib 3.0 revving funny & chewing fuel

[diffo]

The mrs drives an 04 liberty wagon 3.0 auto.
She's just called me to tell me that it is "revving funny & chewing heaps of fuel"
I have had a 1 off where it seemed to hold a gear & rev out a bit more. Not too sure if this is happening to her.
I'm trying to get more info/translation of WTF she is talking about.
Stock 3.0 auto
Kido tuned
Regularly serviced, last being at Subaru (175-180 thou??)
Anybody have any ideas of what may be the problem?? What to look at or where to start?
Thanks in advance,
Diffo
OK translation seems to mean that it is holding the gear changes

Contact Matt and see what he thinks. Could try an ECU reset too.
