Vehicle equipped with 6.2l v8 engine. Have been experiencing hesitation upon acceleration, decrease in power/reduced performance, trouble starting, abnormal shifting (particularly from 2nd to 3rd and 3rd to 4th gear) for about two months. On two separate occassions(once about 1yr ago and the second time about a week ago) during normal use of the vehicle, the car started to shudder and the CEL began flashing. Both times I immediately pulled over and shut off the vehicle. Fluids were good, car has never overheated, regular maintenance has been performed as well. When I turned the car back on, the light was off and didn't show any signs that there was an issue. Two days ago during normal use of the car at about 35mph, a loud knocking/ticking sound started. I was about 1/8 mile from my destination so I attempted to make it there. Driveway is uphill and when I accelerated...

Stopped at a light and went to pull off when the light turned green and the car would not move at the speed of gas I was giving it coasted into the Intersection. I had to turn the car off in the middle of an intersection, restart it and shift back into drive as I got down the road it did the same thing I’ll be in drive and go to apply gas and seems as though the transmission slips causing unsafe driving.

The truck locks start locking and unlocking on their own, the stabilitrac and traction control will cycle between on and off, the motor will shut off, it goes to limp mode, check engine light comes on, traction control light comes on, abs light comes on, it has stalled in drive throughs on the interstate, driving around town, the vehicle is at pat clemons gmc in boone iowa, they replaced the bcm and it is still happening, there is an nhsta campaign #14V61400 for a chassis control module recall, this vehicle vin is not in that, but it does exhibit all the symptoms mentioned in the recall, very much a safety issue as it can happen anytime, especially when it is raining or snowing, started about a year ago
