Tranny won't shift past 2nd

[kdailey4315]

Hey guys,
Just like the heading says. Started my X up started driving and now it won't shift past second. It drives fine but it just won't go past 2nd. ANy ideas? Atime for a new tranny? Rebuild? It's not in 4wd. No CEL. and No 4x4 lights are flashing.
Thanks

How many miles do you have on it? If your pressure is low, it won't shift when it is supposed to. This could be related to loose valve body bolts, bad gaskets, EPC solenoid, internal valve body malfunction, boost valve, clogged filter, etc.
