I picked up my 05 3500 SRW 4x4 with the G56 in it this weekend. When I got to the dealership I had asked the extra quart of transmission fluid had been added to the transmission, salesman said that my transmission “according to the VIN was not included in the recall that needed the extra quart of oil. ” Has anyone heard of this being correct? Did some of them come from the factory with the proper amount of oil? I drove the truck home which is 200 miles with no problems. So either the salesman was correct or I just got lucky. The more miles that I drove the better the transmission shift, no real complaints about the truck so far, but only time will tell.
