any of you ever hear of shift plus imporver it has 2 setting firm or more firm and then a stock for your autmatic camaro its liek 40 bucks is it a waste of money?

 

DONT GET IT!!!!!!! IT WILL FRY YOUR TRANNY, DONT GET IT!!!!! (i had one, i also had a tranny)

 

That thing is junk!!! The only time you will notice anything is when your at low to mid RPM shifts. It will shift harder but also will cost you a rebuild on your tranny. I put one on my 94Z about 6 years ago and within 3 months my tranny was going out. I put a shift kit in when I done the rebuild and gave that thing to a friend and about 6 months later his trans went out.
