Hi guys, I'm new to the forum. just bought a Hummer H3 Automatic 3.5 5cil Petrol,

I have a problem with the 4x4, when I try to place the 4x4 Hi Lock or 4x4 low Lock it only blinks and then it returns to automatic 4x4. e reviewed the engine that goes in the trasnfer and turns perfectly. Also place the 4x4 manually with the help of a plier and perfect coupling without strange noises.

On the screen I will appear to maintain 4wd. that you think may be the fault.

the tcm or the fork of the transfer case



thanks if someone could help me I would appreciate it
