edge evo i think 8 on the shift firmness all across on tow tune...just shifts so weird it would take me a mile long paragraph to type it all out...got plenty of power but when going up a steep hill it will shift up instead of holding the gear,after i get it to shift back down it search's for gears...PMO and it always search's for gears just not always on hills either

Tray it on the Stock tune.

If this behaviour persists, you need to get to a trans shop ASAP - thi is not normal and will likely cause damage if unaddressed.

If returning to Stock corrects the issue, you should consider either leaving it Stock, or contacting PHP for some custom calibrations, or buying a better programmer. Again if left unaddressed yer risking the trans.

BTW - trans maintenance history? Last full fluid exchange with Mercon V? Pan drop / inspect / clean / new filter? Is Current fluid level correct? A lot of folks misread the dipstick. actual level is the level where there are NO 'bubbles' / below any 'dry' spots.
