What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Went for a couple of drives longest was today.
Yesterday it wouldn't lock up going but did coming back. Stopped and had them pull the code and the only one that came up was P0700. Had them clear it and it seemed to be doing fine but it was definitely locking up at random and at some points not at all.
Today, drove 45 minutes and it would lock and unlock again at random. Drive home it locked up then randomly unlocked and threw a CEL. Pulled it again and it was P0700 and P0741.
Even after changing the filter and TCC solenoid, it didn't do anything.
I called my mechanic, and he recommended a transmission shop. He'll be calling me tomorrow to see if he was able to find a reman. Kinda sucks, was hoping to get more out of this one. I also have a billet stall but he wont reuse it because it will void any warranty for the reman so, I need a new converter. Which I'd send mine to get it serviced but they're out 2 to 3 weeks.
Yay
Sorry to rant

I didn't look up the codes. but just as info, if you mean your torque converter is locking and unlocking a lot. I've heard of it being a brake light switch. it you touch the brake it unlocks the converter. so if the switch is intermittent it can cause it to lock and unlock
