Old_Master - what is your level of expertise? I worked for Toyota for several years before a career change. so I know my way around a wrench but I have zero GM experience.

Can I test the encoder motor and sensor easily? will the TCCM report codes and show encoder signals if connected to a OBDII scan tool (I am use to the enhanced features allowed by the factory tools)? "Service light" on my vehicle not light.

DO you have any experience with the alldatadiy.com service procedures - complete enough to include these tests?

Anyone have any OBDII software or a tool that they recommend.
