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.
I have a 2022 3.0 Diesel engine only have 6100 miles on it and it’s leaking oil, pretty sure it’s the rear main seal. Didn’t know these truck were having oil leak problem till TODAY.
