The tunes make quiet a bit of difference in the trans shifts & t/c lock-ups. It's not magic as in if the trans is suspect the tunes will not "fix" anything. My trans has 190k miles on it & I believe it works great with Bill's tunes, so much so that I was going to put a valve body but after putting the chip in I've decided to leave well enough alone. Like I said if the trans is good the tunes will make it better but if the trans has problems I don't believe tunes will help. JMO & you know what they say "opinions are like a$$holes" ... lol
