Hey Marcus, it was quite the change. No if fact that TH350 was a big player in me pulling the trigger on this. It would NOT stop leaking. It leaked everywhere it seemed. All around the pan, and I'd replaced the gasket twice one rubber, one cork. It leaked at the dipstick port and where the shifter went in. So, I was already considering yanking it for a 700r4 swap anyway. Although that would have been cheaper, the 350 still had that old truck smell with no emissions equipment on it. The wife and kids didn't like that at all, so that played into it as well. The 5.3 has 02 sensors, two cats per side, and I used the 4L60e that came with the motor. Now it doesn't stink, and it's nice having 1 more gear.
