I had to take my truck in for TSB 18-NA-365. I dropped off my truck, Mary gave me a ride back home while they took care of the issue, and picked me up and brought me back to the dealership when my truck was done. The only issue, which was no fault of the dealership, was it took quite some time to get the part to take care of the transmission issue. I think there were many, many vehicles with this issue, and the parts should have been more readily available. GM has known about this issue for several years.
