Odometer Just dashed Lines

Every once in awhile my odometer will just show dashed lines (-------). Does anyone know what this means>? Also, my speedometer keeps bouncing all over the place. I got codes all pointing towards the speed sensor, i replaced that and samething, it didnt fix the problem.

the codes i got were- p0720,p0721 and p0722

could it be my trans wiring harness>?

BTW I just put in a t 56 and used the old 5 speed harness.

if its not the harness or sensor, could it be something on the trans internally?

Any help would be great...

thanks

mine did the same 2000gt t45. I took it to a mustang shop witch they fixed it. I dont remember what it was called but its what the sensor looks at rotating on the shaft. some .02 cent fastener came loose. the guys at the shop knew rightaway. on a plus it didnt put any miles on the odo!!

Im hoping thats what the problem is, or its as simple as the harness. i would rather it be the harness, but if its the trans its under warranty, but i would still have to send it back.

anyone know what the dashed lines mean??? im thinking it might do that because i had 5 dtc's at the time.

no one>?
