What are the common issues with the GM 9AT transmission?

[LeArcher]

9AT transmission common issues include increased manufacturing costs due to the higher number of gears; more potential failure points due to its complex internal components; and reduced torque capacity resulting from compressed component sizes to fit the housing dimensions. Detailed information: The 9AT transmission has significantly more internal components due to the increased number of gears, requiring higher manufacturing and development standards which correspondingly raises costs. The complex internal structure creates more potential failure points, and the compressed component sizes to accommodate housing dimensions lead to reduced torque capacity. Additional information: 9AT transmission refers to a 9-speed automatic transmission. The "AT" stands for automatic transmission, while the number 9 indicates nine forward gears. As a core automotive component, the transmission significantly impacts vehicle performance, safety assurance, and stability across multiple requirements.
