Installing Performance Shift feature?

[TheEdgeofSanity]

One of the biggest things I miss about my Bonneville is the "Performance Shift" button. The shifts were so crisp and better feeling than "normal shift". Yesterday, I drove my friend's 1999 grand prix GTP and that car has so more much get-up and go than my bonneville ever did. I still think my alero has good acceleration but could see how it could benefit from a system like this. Is this feature a module that could be integrated on the alero or is it something built into the PCM? Could I simply steal some parts off a wercked grand prix and transplant them on my car? I have considered a shift plus but the switch for that is under the hood and as far as I know, you cannot turn it on and off as you drive.... also, i thought it only increases trans fluid pressure, opposed to the stock option that allows the car to downshift with less throttle application. thanks for the help!

you could try and then see if there is a difference.
