trans shift issue?
 

hey anyone know why my 04 cummins with the auto hags in 1st gear and wount shift till 3500rpm or i let off the gas? any ideas its really anoying:argh:

tow haul mode??? im not sure, just throwing ideas! HELP THE KID OUT!:choochoo::5:

Mine did the same....it was the gov. pressure solenoid

my new 06 was shifting weird and throwing a code they put a new flash in and reset cel shifts better wife says :argh:

yha i think im gona get the new valve body from suncoast A618 with computer it comes with the gov update kit and more plus i can use paddles to shift :U: and it will hold gears untill i shift its cool check it out its under suncoast racing parts:ok1:

my 06 was doing this too, i adjusted the bands and it helped sooo much. I ended up rebuilding it with DTT pieces and parts. :U:
