2006 Equinox with 140K
Particularly in wet conditions, TC light comes on but with a line thru it to indicate "off"- accompanied with check engine light. When these lights are ON, in DRIVE, when I go from 0 to about 35 the car will not shift. I only get a racing motor at about 3500 RPM until I hit 35-40 MPH , then it runs fine. Seems like I have no low gear. At times I can shut the car off and restart and it resets. Sometimes it will not. Codes led us in the direction of shift solenoids. Had the work done to replace shift solenoids- did not help. Had the car back to the same mechanic and he couldn't find the cause of the TC light still coming on. What is tied into the TCM in the Equinox that may be causing this issue? I feel it's wiring or sensor related

all things considered, i'm not very precisely slanted, yet mine used to move genuine hard as well. it wound up being the mass wind current sensor. the attachment on the admission worked itself free, and I would occasionally get hard moves with the check motor light being on. your issue sounds somewhat more confused than mine, however it merits checking. good luck
