Today I was doing some yard work and shifted my 2001 2500 Silverado into 4 low. When I was done, it wouldnt shift back into 2wd. I have been getting a "service 4wd" light on and off for a while but since I hardly ever use it, I wasnt worried about it. Right now I don't have any of my 4wd controller button lights on. Any Ideas on what it might be?

Here is what I did to get it going down the road:

I pulled the actuator motor off the side of the t-case and shifted it into high range manually.

Removed the front drive shaft

Will this hurt anything for the time being?

No opinions on this??

Just so you know we're looking!! Need to put a scanner on it that can read the tx case DTC's. Post them back. Could be the switch assy, encoder/motor, control module, wiring??????????????? The warning light came on for a reason and now that reason has reared it's ugly head and now you need to "worry about it".

You might try backing up a ways to see if your transfer case might be bound up. Things such as differences in turning radius, tire sizes and gear ratios can cause torque bind. If it's in a bind it won't let the gears change, seen it happen before.

samething hapyn to me went to a dealer and they sed my transfer case is but i did took the actuator motor off to but i still feel some noise from front axels this thing on this trucks suck big time :(

no 4x4 lights on and stuck in 4x4 99% chance its your encoder motor, when it happened to me i was in 4x4 high, and no lights on the buttons either...... i had it manually switched out of 4x4 till i could find a new encoder. dont go to gm unless you want to pay 1200.00 plus for it. i found a good used one for 200., still working perfect. just another one of gm`s crappy parts on these trucks.
