#1 depends on whether you're talking about main line pressure (EPC), gear holding pressure, or shifting pressure. Many early transmission strategies reduce pressure during shifts to prevent harsh shifting. Later strategies will often raise pressure during shifts because these calibrations include torque reduction strategies to reduce engine output during shifting.

Outside of that, increased TV pressure will apply more pressure to the clutches and result in more holding pressure. The downside is that increasing pressure will increase fluid temperature and also robs a little power from the engine. On diesels this loss is marginal, but on a gasser it can show up most notably as as lost fuel economy.

#2 is difficult to answer because it depends on several factors including load, throttle position, rate of acceleration, transmission fluid temp., and others.

#3 is attainable by increasing desired EPC in the calibrations.

#4 uses shift pressure modifiers (TV Adder, Slope and Offset) to control how hard the shifts are and shift delay to control how fast shifts occur.

One thing to keep in mind is that most shifting functions are controlled by tables that use an estimated torque output to handle things like pressure and delay. Most of the shift modifications can be handled by changing these values alone so they accurately reflect the amount of power the engine is producing. The other tables and functions are for fine tuning.

Take care.
