Stuck in 4LOW

Asked by Jun 14, 2015 at 08:33 PM about the 2003 Chevrolet Silverado 1500 LT Ext Cab Short Bed 4WD

Question type: Maintenance & Repair

hey there, last weekend I sunk my 03 Silverado about a foot of water in the cab, got it running with a slight misfire, but my problem that is bothering me is its still stuck in 4LOW.

I have auto transfer case.
ive already tried a new 4x4 switch, transfercase control module, atm I pulled off my transfer case motor (when still plugged in I hit 2wd but didn't see motor move I think)

I can only think of replacing transfer case fluid, new t case motor, ground wires or maybe the front diff actuator?

all help would be appreciated I work in a few days and im broke..

I would change the transmission, transfer case and front and rear differential fluids ASAP. Chances are that you have water in some of them.
