My 2011 Tahoe was one of the early AFM engines and the only time I notice it is when I am driving between 29-35mph and the thing keeps switching all the time. While towing or at any other speed it is totally imperceptible.
I agree. Something is wrong.
The F150 will fix the Chevy problem. Just research the issues. Sometimes the Devil you know….
x2. Our 2014 Yukon 5.3L is noticeable sometimes at those speeds. It feels like a very slight shudder or at least change in engine sound/vibration.
Turning tow/haul on does not disable AFM, at least on ours. I read somewhere that M mode does disable it but haven't tested that yet.
