My 2023 suburban engine failed with 16,900 miles. The dealership said on the screen by screen analysis of the computer said the coolant temperature was over 300 degrees then engine temperature was almost the same. Would it stand to reason the same cooling system that cools the engine cools the transmission? GM warranty division said to replace the engine but not the transmission. When I try to trade off the suburban the dealership doesn't seem to be interested in wanting to trade. I have tried for 2 months to get help from GM to no avail. Have asked to talk to supervisors and they never call back with any help. Does anyone have any ideas?
