Need help

[Shannon R]

I have a 2004 expedition 5.4 4 WD. Speedometer not working. Transmission not shifting out of 1st. I fixed code P0720, Output speed sensor, but didn't help. At this time. Check engine light not on and throwing no new codes. Any ideas???

Welcome to the site.
Output from the oss is used to determine shift points. Since your speedo isn't working the p0720 issue hasn't been fixed.
Do you have a scanner that can read live data?

I'm not sure. I have a centech obd 2 reader. I got it at harbor freight
