i know its not safe and yes it will void your warranty. That other guy spewing crap out of his mouth doesnt know what he is talking about.
The way this product works is it causes your trans fluid pump to work at either 50% or 100%. Now yes the pump was designed to work at those rates, but when you turn this on, its constantly at those rates. It can very easily burn out your trans pump and just destroy your trans. The way your trans normally works is right before its supposed to shift it ups the line pressure with the pump to allow the shifts to be normal, then quickly goes back down. With this kit its constantly running at 50% or 100%.
Like said before by someone, after using this for a while stock doesnt feel right anymore. I had one on my last car a 2001 Cavalier Z24 Supercharged. After about a year of use, if i turned it off the trans would slip so bad i would have to let off the gas in order for it to shift.
And again, THIS DOESNT MAKE YOUR CAR FASTER!!!!!!!

no it doesnt make your car faster, i tested mine at the track. I ran a 14.7@92MPH with it on setting II and i ran a 14.7@92MPH when it wasnt on at all. This was done when i just put it on so my trans was in good shape. And like i said my car was a better test car than most of yours because i had an additional 50HP running through the trans.

Another note on the testiment that this will ruin your trans. I eventually removed mine permanately because it was causing drivability issues. After a few hard runs and hard shifts, the transmission would start acting really funny. I would be cruising at a normal speed and the trans would just start to randomly up and down shift on its own, with no throttle change of my own. It would just bounce up and down between 2nd and 3rd gear. If i turned the shiftplus off, the trans would act normally as it could as this point. Or if i let the trans cool down it would act normally again.

are you seriously trying to say the shiftplus makes your car faster because it damanged the trans so bad you cant drive it hard without it being on, therefore making it a worth while buy?

But isn't the purpose of the Shiftplus to lower shift times in order to reduce internal clutch slippage and prolong the life of the transaxle? I mean I'm no 23 year old. I'm just a 34 year old ASE certified master technician with over 10 years of experience working on GM vehicles. I may not know what I'm talking about. Granted, there are kids on here who just want to chirp their tires and try to be cool, but not everyone who has posted on here is an idiot. Of course, if someone installs something like this they should be prepared that it might have adverse effects on other components like axles, ball joints, motor mounts, control arm bushings and even strut mounts and bearings. There are down sides to the product but, as far as the transmission internals are concerned, I'm sure it accomplishes it's intended results when used properly and resposibly.

I'm not going to argue with you that, at 23, you have more experience than everyone here.
