Once in 6th , it still drive fine until i hit the pedal hsrd to pick up speed (hill, passing cars, avoiding accident) it doesn't want to downshift to 5th without some real pedal work. Not a huge problem on the 30hp setting, but on the 120hp setting its a different story. The truck lugs and hops like its hitting rumble strips. Almost sounds/feels like a misfire. When i manual shift down to 5th it goes away and pulls nice and hard. I use the 120 hp because ingot bad mpgs on the 30 and 60 and the 120 has been great so far...
Ive basically just been driving with the tow/haul button on most of the time, which eliminates this problem, but I'd like to know if theres anything i could do different or any updates to the trans tuning.. My trans pressure sits around 90-100 idling, 120 mostly droving but taps 160's-180non hard runs. (Without tow/haul on fyi)
Again, not a huge deal and doesn't happen all the time, just in those circumstances...
Just my situation.. Thanks all..
