I still haven't gotten an answer to my question. And now I have been charged amother 21 dollars I did not authorizeWill someone help me please
Expert:  Chris (aka- Moose) replied 1 year ago.

You are charged the full question value as soon as a tech responds to verify you have funds to pay for the help your getting.

The code is for a transmission concern, not for the other issues you mentioned so I assume your focus is more so on the symptoms you listed.

Do you own a diagnostic tool that monitor communication wiring and signals since the radio is not turned on via a fuse but through the communication wires?

Customer: replied 1 year ago.
on the diagnostic tool .. both a Bluetooth OBDII reader and apps a gm diagnostic reader..
Expert:  Chris (aka- Moose) replied 1 year ago.

Will your tool communicate with the radio and if si does it show the radio being signaled on?

Customer: replied 1 year ago.
I will check the GM tool here shortly to see if it can connect to radio.... if you know s phone App that provides that .. I own of the more compatible OBD II interfaces
Expert:  Chris (aka- Moose) replied 1 year ago.

I have never used a phone to diagnose a vehicle, I would be no help with that.

Expert:  Chris (aka- Moose) replied 1 year ago.

Hello again Chris here,

I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears your not pleased, or need more help.

Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.

Thanks Chris

Had a medical emergeny yesterday to deal with .. I will be working on it again today. It appears my diagnostic toold can't read radio .. only the OBD port error codes and engine operating conditions ... I haven't seen a radio option. You say transmission for the code and if you look at my early noted the combination of gear shift up and down sometimes releasing the condition ..and the condition moat often triggere ed ... after stepping on brake .. shifting to drive then hitting the gas and the senseor for transmission to gas pedal and brake. What do you recommend ... where should I start next
Expert:  Chris (aka- Moose) replied 1 year ago.

The only thing I have left to offer not being there in person is the diag steps for the code that you have. If that would not help I can opt out and get you back on the waiting list.
