Will be leaving this post as chevy can't figure out the 3.73 gears and degrees system issue. Is a super truck but can't use it and haven't for 4 months... chevy tells me 4 to 6 months... not they are buying it back... worst thing I ever did was try this diesel...

I'd like to know the procedure you used to do what your suggested I had to tear my entire front grill take off the condenser radiator and fans off as an assembled unit and as you'd suspect I had to drain all the fluids out to do this. Once i got it back together I started getting this code and I can't still to this day get the valve because it's still on back order.
