Trans Shifting

i tow a fifth wheel trailer weight is about 10,000lbs. i noticed that when the trans shifts it seems like it slips into a higher gear rather than giving a firm shift. it only does this when towing or when under hard acceleration not towing, under normal driving conditions it shifts fine. i recently installed the diablo predator programs. with the 40 hp program in it shifts ok maybe a little bit of a sloppy shift. with the 60 hp program installed the problem is magnified immensely under half to full throttle. has anyone else encounter this and what was the fix? or do i have a bigger

If I'm not mistaken your Predator has the software on it to custom tune the tranny.

You can do as cookie said, or also get a shift kit, sonnax valve and tri-springs. A fairly cheap mod that firms up your shifts, can install yourself.
