Any of you guys cruise around on level 4? I don't have the Attitude, so changing the setting on the fly isn't possible. It seems that the truck under normal driving conditions, runs smoother and gets better mileage than on level 1.
I am concerned that even though the truck never sees WOT into 3rd, 4th, and 5th gears, that just cruising at level 4 may cause tranny issues.
Do any of you have knowledge of this causing overheating or anything else I should be worried about?

It may eventually cause trans issues over time/depending on driving habits. But i drive everywhere in lvl 4. To me it shifts better and maybe a little better mpg's than in lvl 2 or 3.

Does not matter if it does not see WOT in 4 or 5...it may not happen tomorrow, but it will happen. Back it down or be prepared to see the Tranny Gods.

Level 4 was the best my Edge could do on fuel mileage, I checked it over 2000 miles. Too bad 3 of them failed on my truck.. I went to BullyDog and am getting about .5 better mpg in Performance Level. Although it could be the Meaner Power Kleaner.
