2011 mustang auto trans

I still have a problem with transmission not shifting at WOT in the 4-5 shift.I can let of the throttle and it will shift,but when I get back in it it jumps back down and the tach lites up 7200 rpm.I don't have too many chances to go that fast around here,or I would have got back to u sooner.I am running the dynotune with the Steeda tune u sent me.This is the latest update that came out in September that I'm using. Are the shift points adjustable now? thanks Bud

Hmm, Bud, email me your last tune written and the backup and let me see if Ken has anything to try

I finally got a chance to air it out today.The button off just like when started. When the engine ran up against the limiter I was at 140 in 4th.IT shut off I lifted pushed the button and got back in . It held in 5th untill I ran past 165 to see if the 5-6 change would work at WOT,but ran out of road and had to lift. I held it on the floor for at least 3 seconds between the 4-5 shift & no shift until I lifted. I don't think it was the button that made it shift, I think it was the lifting of the throttle.It wouldn't do anything until I lifted and got right back in it and hit the button at close to the same time so I can't be sure It was already in 5th when I got back in it,it felt like. The 5-6 shift I don't know.I will have to find a longer stretch of road!The button off will work great for the street.It shifts much better than factory and it dosen't clunk&clank like the factory tune did when downshifting in the lower gears.People who want to loose their driving privileges, like me I guess, will be the only ones that will need a WOT 4-5 shift.This might be a problem if you have 4:11s or steeper gears.Thanks for working with me on this Mike.I will try anything you throw at me.(It would be great if it shifted harder with the button on)You could run for President if you could make that happen.
