Ok, in short, I snapped my input shaft when my truck wheel hopped thru and intersection. I had it replaced and the transmission rebuilt (stock parts+ existing converter) and got the truck back last wednesday. Everything was good, shifting was great (I had them fill it with John Deere Hy-gard fluid). Well, Thursday night I ran around all night giving the transmission hell and nothing happened. Then Friday night I race quite a few people and Then I race one of the guys I know on another forum in his twin-turboed 24valve.
The second time I raced him, at WOT my transmission wouldn't shift into 2nd. I would have to let out of it and get back on it and it would shift. I beat him, but ever since then my truck wont shift into 2nd anywhere past 75% throttle. It wont even shift into 2nd manually, but if I am just normally driving it will shift. What would cause this to happen all of a sudden??? :bang
 
I've adjusted it as much as I can, it helped a little bit, but the problem persists. You think I should adjust the 1-2 shift band? I am just wondering how this can happen all of a sudden
