Default O/D Off light FIXED?

Alright guys, so those of you I talk to often and those who went to the Florida meet know i've been having a problem with my O/D Off light sporadically flashing by itself on the highway with no symptoms. The code was coming up as torque converter circuit malfunction. I had no idea why it would do this. Then, a few weeks back I finally went under the truck and just started playing with the connectors for the hell of it. I found that one of the connectors wasn't fully seated into the socket, so I pushed it back in and test drove the truck the next day. No light all the way to school, or home. However the next day on the way to school, I got the light. Got to school and crawled under the truck, and what do you know, the connector had backed out again. So I began to try and periodically get under the truck and push the connector in. As soon as I started to do that, the light stopped coming on, and I haven't seen it since last Monday when I started checking the connector daily. Well, today I figured out what exactly is wrong with the connector. The connector has a little metal thing on it that locks the connector onto the trans. There are two little black nubs on the sides of the connector that this metal piece pivots on. Well, one of the nubs is broken on my connector, so the metal piece keeps coming up on that side. When this metal piece is unlatched, the connector is allowed to come out. So since this metal piece doesn't fully latch, my connector is shaking loose due to my alignment being off. When the connector shakes loose and the trans does it's self scan, it's not receiving any signal from whatever is on that connector, so it trips the light. So, for now i'm gonna wrap the connector in electrical tape, but down the road I have a new connector to order and install. I had gotten 6 quotes to fix the code, none of which had anything to do with the connector, or were anywhere near as cheap to fix. I had shops say it needed a new TC, new solenoids, even one said it needed a rebuild, all of which were to the tune of $500-$2500. Yea right.
