P0740 Torque Converter - Circuit Malfunction

02 TJ 145k Miles
32 RH 3 Speed

Check Engine light turned on today, pulled up the code and it read P0740 for the TC. Its strange because I had the same thing happen over a year ago and nothing came of it. I was driving one day to a buddies house and the light just came on, within a few days it turned off.

I've never had any signs of a bad TC such as slipping or oil buring. I changed my trans fluid about 4 months ago and it has been red ever since with no burnt smell.

I am curious if anyone else has ever had this issue, and if anything ever came of it? I am making a trip to Silver Lake Sand Dunes soon and I am worried I may damage something but then again, it did this over a year ago and nothing came from it.

What should I do?
