[QUOTE="Black_Pstroke, post: 414013, member: 126"] Ive been messing around with the shifting tunes on my truck. I originally started out with X street on Stock/delay and the shifting seemed to me to be very harsh. So I switched to Xstreet with firmer delay same issues. A few weeks ago I had to pull my boat a fairly long distance so I loaded up the street tune and left it on firmer delay. It shifted a lot better but I got some messages on my message board. So I switched the tune from street to Xmild and left the trans on firmer delay. This was the best the truck has ran since I tuned it, ran great minimal smoke and trans shifted damn close to stock. Well today I decided to load the X RACE with race lock and go see what it had. I went through the trans learn procedure that is on here, and the shifting was just short of violent. I have heard many people say they run that combo for DD, but the way it was shifting there is no way I could deal with that. So I get back home load back to X MILD with firmer delay. Go back out and go through the learn process again, the shifting calmed down but it was still not as good as it was before I switched tunes back. Im completely stumped on what is going on. This is my first tuned auto, so maybe I just got used to the smooth shifting of stock, or maybe there is a problem with the tune???? I dont get any CEL's or messages in the message center(except for what I mentioned earlier). If I am lightly getting into it the first 3 shifts seem really harsh, and the last 2 shifts smooth out a little. When really getting on it, it is pretty similar except 3-5 shift a lot better. Any input would be greatly appreciated.. Sorry for the long post [/QUOTE]
