Transgo TF-2 question

Thanks and point well taken, I'm putin it back together with out the Command feature. Actually thats what i've been thinkin about for the past 2 hours, what is the point of downshifting at any rpm. But also I had been tryin to figure out how to install the spring over the piston for the rear double band and also should snug a double band and losein it 3 1/2 turns or 2 1/2 turns. One more question what will it take to make a 904 a heavy duty 904. I had mine rebuilt about 3 years ago and I notice while going through the valve body that some things had been done to it already and i also noticed it had a double band not a single rear band. The clutch barrel that holds the bands also looks new.
