Regarding GM\u2019s 9T45 automatic 9 speed transmission.  Problem: - The GM Adaptive learning of the transmission does not have safe guards in place to prevent unsafe sift patterns and behavior. This results in shift flair behavior where the transmission will drop out of 3rd gear and pause before shifting to 4th gear. It will learn to lock out 9th gear  and it will max out with 8th gear at freeway speeds reducing MPG. And it will fail to downshift appropriately while driving leading to the operator wondering why the vehicle will not accelerate when needed; this casual downshift delay then results in excessive downshifting to the lowest possible gear where the vehicle will then lurch forwards; and then it will pause and maintain said lower gear and continue accelerating for 1-2 seconds while the operator presses the brake pedal in response of the vehicle jumping forwards.  Individual situations: 1) Lack of 9th gear use at freeway speeds. This is reducing the advertised emissions based on EPA testing. This behavior skews official EPA test results because vehicle operation is not as advertised. 2) Shift flair and unsafe shift delays. This is the most serious behavior. It leads to pauses and delays in acceleration of up to 5 seconds, and it leads to pauses and delays where the vehicle continues to accelerate up to 3 seconds after letting off the accelerator and pressing the brake. 3) Excessive wear. The badly learned behavior is causing issues with shift control pressure and logic, excessive clutch wear leading to damage and worn clutch packs.  Analysis: - Resetting the GM Transmission adaptive learning to factory removes these problems, the trans will relearn bad behavior within 2-3 weeks of daily driving. Reset was performed using an Autel Hot function \u201cQuick Learn\u201d procedure for the transmission.","products":[{"type":"Vehicle","productYear":"2024","productMake":"GMC","productModel":"TERRAIN","manufacturer":"General Motors, LLC"}]}]}
