2015 Silverado transmission 1st slipped out while under load. Then continued to slip out until back on highway. Then traction control Message came on and retarded acceleration. Couldn't turn off traction control message. Made it to mechanic. Scanner said codes were electrical related. Reset after and drove 6 blocks and traction control Message back on with retarded power all the way home. Shifted ok..a little hard but problem returned. Probably can reboot and clear computer if disconnect battery..Any ideas or feed back is appreciated.

 

I think a lot of potential help might get missed because this is the Venture forum, the Silverado section is elsewhere.
