2008 Ford Focus Automatic?

My car won't go into reverse and when I go up hill its wanting to go into" limp" mode

Check the fluid. Check for trouble codes.

Gee that's too bad. We all experience problems of one sort or an other. So what's your question?

Find local shop at ATRA.COM for more help

Wanting to go into limp mode? Either it goes into limp mode or it doesn't!
If the rpms go up and the vehicle doesn't move faster or at all you need a rebuilt tranny.
Have you been getting the ATF and ATF filter changed every 60,000 miles?
