It means the torque converter clutch solenoid is having a problem. Almost certainly that means drop the pan and replace the solenoid. I don't have a diagram to show you which of the seven in there is the problem solenoid.

Not to scare u but my tow haul light came on when I first purchased truck. Took in to dealership to get looked at. 3 weeks later and rebuilt trans it was clutch plates that were bad. But at first they thought it was a computer issue.

If you mean a dealer, then yes, they can. When you go to the parts department to get the solenoid they will have a diagram of the solenoid body and will be able to show you which one it is.

They are very easy to change.
Drop the pan, yank the filter (which you might consider changing while you are in there) and they are held in place with nothing but a 2-wire electrical connector and a small e-lock snap ring.
