    LMM: MAF Sensor Code P0101

    I have a 2008 LMM with 70k miles on it. I am having an issue with my MAF sensor throwing a code after idling for 10-15 minutes. The output on the sensor is saying 42-45 gr/s.

    Hard Down Shift from 2 - 1

    Hard Down Shift from 2 - 1

    I have a 2008 Suburban that I had the 6.0 gas swapped to a 2008 LMM Duramax. I am having an issue with a hard down shift when coming to a stop. If I completely stop and immediately start again it will slam into 1st. If I stop and give it 2 - 3 seconds it will not happen. Any thoughts?
