Yeh, but what he's saying is he is letting off the gas and then going back on it. I can't see how that would do any harm with a torque converter in the middle unless he tied it to a tree first?

well torque converters work on a hydrodynamic principal (although similar to but differs slightly from a hydrostatic transmission), so if his constantly stalling and accelerating the vanes hes putting extra stress into it before it can attain coupling, obviously oil has a high sink rate (heat soak),but equally once its absorbed heat it doesn't easily dissipate it which is known as pumping loss which in agricultural/plant machines is dealt with by water cooling.
