I recently made a statement about towing the high mountain passes of Colorado. MOJO advised against my advice.
I questioned my advice after making the statement and did some research. I also contacted my mechanic who is the head mechanic at a Chev dealership where I live.
My conclusion is, my advice was wrong.
It is best to be in 2WD in the "tow-haul" mode( if you have it) and manually down shift to control your speed. Start out slow at the top and control your speed in 2WD.
Thank you MOJO for bringing this to light.
My apologies for giving incorrect information.
