There were very few of the comments that were meant to be helpful or even attempted to be helpful. Most of the comments were from fanboys to try to discredit me (e.g., its normal, you must just not like automatics, etc.). Those guys get irritated if anyone speaks of Camaro problems. They are all over this board and most ever other board of every type of subject. I called them fanboys because that is what they are and it is obvious from reading their comments.

Here is a small sample of this problem being a major defect in the new 10 speed auto:
https://static.nhtsa.gov/odi/tsbs/20...39046-0001.pdf (It states improvements to the pump drive gears were made in 2022, but they must not have been good enough improvements because it happened to my 2024).

Interestingly, I read that the Ford version of this transmission does not have this problem because Ford designed the gear with "straight cut" teeth. However, GM wanted a quieter transmission, so some GM DEI engineer changed the Ford designed gear to have slanted teeth for GM 10 speeds which causes the problem by putting too much side pressure on the gear bearing assembly, which it was not designed for, which causes the gear bearing assembly to fail, which causes the gear damage and ultimately the pump to fail to work properly.
