I have a 2001 F150 xlt 5.4L V8 with an automatic transmission. I checked the code from my check engine light and it was p0122, low voltage/ throttle position sensor. So I changed the sensor, had it cleared and then a few weeks later got the same reading. It has been intermittent though, the light that is, but I have noticed the tranny shutter from time to time more so when going up an incline and also some strange shifts at higher rpm. Could these problems be related or do I have a transmission problem as well?

Thanks,
Dave
