Code problems unlocking converter

I have some code issues that have just shown up that seem to be causing my updated tunes to be interupted. My converter is unlocking and shifting funny.
Can anyone advise me who knows how to fix these codes.
1. DTC code PO500 Vehicle speed sensor A

2. P1000, OBD system readiness test not complete.

3. UO100, lost communication with ECM/ PCM
I hope its just a bad connection.

Thanks guys C.J.

Don't worry about P1000, that is normal. U codes are communication codes, and they are tuner/monitor/wire related...not tuning related.

P0500 possible causes....

• Open in the VSS harness circuit
• Short to GND in the VSS harness circuit
• Short to PWR in the VSS harness circuit
• Damaged wheel speed sensors
• Damaged wheel speed sensor harness circuits
• Damaged ABS module
• Damaged PCM

C.J., your tranny/converter issues need to be talked over with the person who built the tranny. It doesn't have anything to do with the tuning.

The VSS error can also come form pissing the ABS module off in the snow/rain, etc...

Your info on the codes is appreciated.
The trans converter issue existed, we upgraded the tunes with mick and the converter started locking correctly again. Then it stopped locking correctly and threw these codes.

The codes have nothing to do with the tranny, so not sure how they would be related in anyway to your converter issues.
