4x4 engages automatically when driving my 2001 GMC Sonoma SLS When I start my truck up and put it in gear (automatic) there are a few times it kicks into 4wd automatically without hitting any of the buttons. Sometimes into 4 High and sometimes into 4 Lo. What causes such a problem?

2001 gmc sonoma 4 wheel drive slipping the lights on switch work goes into 4x4 but when you accelerate it slips out when you let off it goes back in any ideas?

Hello RD.
Yes, Inside your transfer case there is a clutch that is made up of several plates that are designed to slip when there is a difference in torque between the front and rear.
If improper type of fluid was put in or if the fluid levels were allowed to get low it may have caused damage.
If indeed that improper fluid was put in, drain and refill with the proper fluid.
