PCM updates
Just wondering everyone's opinion on how important it is to do the PCM transmission and transfer case updates as recommended by the dealership? I have an 06 Chev Silverado 1500 Max (HD). What do these updates do?

They just hook up their computers to ur truck and install updates. Runs about $120 i believe. Takes a few hours.
