Well, you're posting in the wrong section, and the transmission control is quite different with the IDIs. But this may be a speedometer/PSOM/VSS problem, not a transmission control problem. Anyway, your pic does not show a mechanical odometer, nor does it show a 120-MPH speedometer, as you stated in post #3. So once again, when the speedometer malfunctions, does the odometer continue to display a number, or does it go blank?

Sorry again- just realized I was posting in wrong section-I say mech. as in not digital so where would a number be showing? I replaced the vss in diff. the psom seems to jump around when I turn it off is the only other thing I've noticed

It very well could be. The 96 C&C had the ABS light on, and no/bouncing speedo when the wire needed repaired.
