I don't know if it's my place to say, but I have noticed that most all "custom" tunes shift ridiculously hard for no reason. It's an easy fix to make them normal again. However, for some reason, most tuners go crazy with the shift firmness.
On a side note, the 4R100 transmission is most vulnerable during the 1-2 shift because of what's going on inside the transmission. The intermediate sprag is pretty fragile and doesn't live long with high torque upshifts.
I would ask Bill to set the
torque tables,
minimum TV ,
TV during the shifts,
desired shift duration and
torque reduction during shifts back to near stock levels for the daily driving tunes to make them acceptable. The hard shifts are fine for most people, but they're not for everyone. This is the reason most tuners command a firm shift. They know that a longer "burn time" of the clutches and the band is a bad thing. The more power you put into the transmission, the firmer the shifts
should be to reduce the slippage. As long as you're not pushing the truck with the added power, a near-stock shift strategy works just fine and won't hurt the transmission. If you're after the best economy possible, then you're probably not driving like a wild man anyway, right?
If you have any more questions, feel free to ask!
