Hello all, I'm having an issue on my 2002 F350 7.3. Today I hop in it and drive off I notice my speedometer stopped working. My overdrive light on the shifter started flashing. The trans seems like its not shifting correctly. It will eventually shift into overdrive but not always. Also now when I start off my fuel gauge raises and when I come to a stop it drops all the way to E and causes the ding and fuel light to light up. I figured this was all due to the VSS being bad. So I drove over to Autozone bought another VSS and a cheap tool set and changed it in the parking lot. No dice. I do have a scanner to pull the trans code but its late and I just got home. Has anyone else run into this problem before?

 

Without the codes you're just shooting in the dark.
