ok so I just bought a new chev and it has the electronic shift 4 wheel drive but when I first start the truck it always puts itself into 4low and it wont shift to 2 wheel drive unless its in nuetral and when it does shift it makes 2 loud clucks
So the question is has anyone else had similar problems or know what could be causing this? I have no idea ive replaced the electric dash switch but that didnt work.
Thanks in advance

Pretty common in these years. Happened in my '03 Avalanche as well. I think there is a TSB for this. Might still be covered for ya.

TSB = technical service bulletin.My 07 did that too,and all four brakes would lock,and it would sometimes go into 4 wheel high while cruising down the hwy at 65+.And it leaked so bad it was like a swimming pool in the cab.Truly it was a POS,and I bought it brand new too.
