4L80 codes

[twisted60]

I’m trying to check DTC codes on my 2005 M1152 and it just respetes 12, I let it run thru 7 times and just respetes 12, is it safe to assume there are no problems with TCM ? I dont see anything in 4L80 manual or ™’s addressing this.
Thanks Rick

A repeating 12 means no codes, are you having transmission problems?
That is in the troubleshooting guide
