Hello, we just got a 2016 kenworth t880 with the paccar mx13 engine and gen 3 ultrashift plus.
After driving this truck for a day it seems like theres a problem with the transmission. When starting out the engine goes up to 2000 rpm and sometimes over 2000 rpm on every gear and it also feels really slow as if its in low gears. Also noticed once or twice that the engine goes to 2200 rpm and transmission wont shift for a couple seconds. Anybody know whats the deal with these? we dont have much experience with the eaton ultrashift transmissions.
Eaton Ultrashift problems shifts at really high rpm?

Are hold the go/go padal close to floor, try only giving it 3/4 or half of it when you want it to change gears to see if it changes the way it winds out before changing up to next gear?
