If you like a smooth shift do not get one. It makes the shift on the neck snapping side. But, if you're into a faster shift, it could be for you. Only way I see the Vette servo making the shift harsh is if you use it with jacked line pressure in the programming. Once my tranny is out of warranty I will be putting one in seeing as GM saw fit to even put it in my 96 Roadmaster wagon.
I am not saying hard shifts are good, that will break this tranny, but quick and positive shifts are good and that is not stock. What the servo does is provides more area for the hydraulic pressure to apply the second gear band, just playing with the programming tries to accomplish more positive band hold by just jacking pressure.
Wouldn't the result be the same? The servo increases area to a fixed value, but the PCM can modulate pressure to variable points. With faster and firmer shifts it doesn't allow the tranny bands to slip as much keeping the tranny from wearing as quickly.
I would recommend a corvette servo and shift kit if you want more bang for your buck. With k on the tranny I would be a little hesitant to change anything Just because there is more than one way to skin a cat does not mean all ways are equal. Your mind is clearly made up and no amount of information or expeience will change it. My tune from BBear increased line pressures in my transmission, and the shifts are all noticably faster and smoother.
Why do you say that, I was asking a question I'd be interested to hear the difference between a larger surface area servo vs increasing line pressure via e-controlled pressure regulation. I really don't know The Corvette servo allows for equal apply pressure across the servo piston for more positive band apply and hold. Jacking up line pressure wont do that. In fact, jacking it up too high stresses the pump and will break pump rotors, a big problem in 4L60E's.

The corvette servo will help improve the firmness of the shifts, especially the This allows the shift to happen quicker which will reduce slip inside the transmission. A corvette servo upgrade is a good idea for any type of towing. Since towing puts added stress on a transmission which will increase the fluid temperature, it is smart to make whatever upgrades you can to allow the transmission to shift as best as possible.
A corvette servo can be installed without dropping the transmission out of the vehicle. It may be a tight fit in some cars, but it is quite doable in almost every scenario. As stated previously, the purpose of the corvette servo is to help improve how the transmission shifts.
