Noticed transmission slipping. Had fluid changed, seem to stop for a few months but is back again. Tripped code this time. Not sure what to do.

I do not have a solution yet, but I got code P0773. The check engine light has been coming on radomly and sometimes the O/D light comes on blinking for a few minutes. I am trying to find where the lock-up solenoid is and I'm trying to figure out how to test the system to make sure that it is the lock-up solenoid.
