I just put new locking hubs on my dana 30 becuase i torched the set of warn hubs that i had, now when i drop it in 4lo and try to drive down the dirt road that leads to the trail i cant get the tranny to shift out of second....It used to shift into third and drive halfway normal until i got to the trail....it also feels like my tru trac isnt unlocking? feels like this because the wheel pulls hard to the right (it never did this before)....

When driving in 2 wheel drive the tranny shifts just fine...the only other thing i did today was install a tranmission temp gauge (i used the autometer manifold and tapped the tranny line)

specs are 5.3, 700r4, dana 300, dana 30 front dana 44 rear 4.10 gears

sounds like you have only one hub engaging? (the pulling to the right problem)

low on tranny fluid? (shifting problem)
