I LIKE CHEAP STUFF.....
Well, I'm beginning to think my tranny might be on it's way out the door mechanically, unlike the initial thought of it being something related to the computer. Here is my other thread about it randomly starting to shift weak from 1st to 2nd. Truck is a 2006 crew cab GMC 2500HD with 6.0L gasser and 4L80E tranny, 4x4, and about 120k miles.

Never had a blip out of this truck until lately. Had it 3 years and have put about 25k miles on it in those 3 years. The thread above will explain how while questioning what would make my tranny start shifting weaker from 1st to 2nd than usual, I had a Throttle Actuator Control Module fail out of the blue causing it to go in limp mode constantly, enough to where it wasn't driveable. Got the TAC replaced and it's fine now, been driving the **** out of it.
Now it was mentioned that over time if you paw paw your truck, even after having a programmer on it, the computer will adjust shift pressure accordingly per driving style. When I was having problems with the TAC I reflashed the stock program back in it until it was fixed. Then after it was fixed and performed fine (fine meaning not going into limp mode) for a few days, I reinstalled the Diablosport tune. It was still shifting about the same weakness with the factory tune as it was prior with the Diablo tune, then after reinstalling the Diablo tune once again, I even upped the shift pressure and downshift points even more than before, and it STILL shifts weak into 2nd gear.
Main thing that worries me, is when it's still cold and usually when I get to the end of my road and start off from a stop sign, it will slip for just a moment after pressing gas and not move, then it will catch and go. It's not a long instance that it does this, but it's enough to be like what the hell?! That ain't supposed to do that!. It's only done that about 5 or 6 different times lately that I can remember over the past couple months, but after talking with a buddy of mine I work with today, I'm getting kinda worried about it.
He recently just traded around and got a deal in a 04 or so model 2500 Suburban 4x4 with the 8.1L gasser in it. It has like 219k miles on it and he said he just had to put a brand new tranny in it that cost him $2,300 with 100k mile warranty. The way he described his acting was exactly how mine is doing with the slipping from a dead stop when cold for just a moment, then going, except the way he talked, his was doing it for a much longer instance than mine....so I'm thinking mine is just in the early stages of progressing to where his was before he finally carried it to get worked on. He got a steal in the Suburban and still doesn't have much in it after dropping $2,300 on the new tranny, but I cannot afford to do that right now.
I know the worst thing I could do right now is change the fluid and filter, that would definitely assure it to be burnt up and useless way quicker than the rate it's going now. I checked the fluid about a month or two ago and it seemed full and to be of good color, but I didn't smell it to see if it smells burnt. What do you guys think my options are here? If it's definitive that the sumbitch is about burnt up, I may start looking around at dealers/car lots and try trading and getting out from under it while it still isn't slipping bad. Ugh, fawking pisses me off. Think these tranny's are rated at towing around 7k lbs or so, and that's about how much my truck and trailer weighs, but I've never heard/read about any problems with the tranny's at only 120k miles.
