Over the last 3 days my trans has started having 2 different shifts. When I 1st installed the tune (about a week and a 1/2 ago) it shifted a little harder and faster. It still shifts like that most of the time.
The other shift is HARD, and I mean real hard. 1-2 shift at 3000 rpm will bark the tires same with 2-3 shift. 3-2 shift when flooring it will roast the tires. The only way to get it back to what I think is the "normal" programmed shift is to shut off the truck then restart it. I have noticed that it will go into "hard shift mode" some times when I get on it then back off just before it shifts. But not all the time. So is this a sign that my trans is going out? Thanks
