Transmission upgrade for 1997 Sierra 4.3

Yeah, I know I need a bigger truck but this one just had a new motor installed and I only have 3k on the motor. Moving to another town. Even when not towing the trans is constantly shifting. I can say the word incline and it will shift. Lol

What performance transmission is available for the 4.3 V6 automatic? I need something for towing a trailer.
