TUNING SHIFT PRESSURE'S ??

Im about to do the J-mod, then if its still to soft (doubt it) ill use a Diablo to firm it up.
From what i understand the less time it spends slipping during the shift the cooler it stays. A cold auto tranny is good.

if you are turning it up via a tuner like the SCT Xcal or Predator, the max settings should be safe on a stock tranny.

From what I am able to surmise, you can only increase the pressure up to a certain point. That point is where there's not enough fluid to pump through to make your shift happen any faster. That point of fluid starvation comes before the point of over pressuring the system. Some people have claimed they increase their shift pressures but at a certain point (like after 7 on a scale of 10) they don't notice the shift getting any firmer. I've increased my shift pressures to the max before but decided to back off since it was too harsh for daily driving.

On another note, I haven't found a firm reference to this 3-4 being the weak link on the newer transmissions. I remember seeing something about it being true on the older ones. Yet, many people state that "weak link" like it applies to all transmissions. <shrug>

I guess the tuner have a safe guard built into them? Is that a safe statement?
