Less likely to happen when AFM is disabled. I hate GM for doing this to those motors.

[@gabrielreesemobilemechanic]

Yes, I agree. I believe they introduced this in 2007 or 2008.
A 5.3 LS pre-AFM is priceless

@gabrielreesemobilemechanic i have a 2015 Yukon denali with the 6.2, i bought a Range dongle to disable it technically.

[@gabrielreesemobilemechanic]

@@oSTYNCLSYodoes that work? I haven’t read much into electronically disabling AFM

[@oSTYNCLSYo]

@gabrielreesemobilemechanic yes they work 100% it will keep the motor in v8 mode, and to go back to "stock" just unplug it from the obd2 port. My experience it will also make the vehicle shift smoother.

@@oSTYNCLSYowow that’s awesome

Why can't great mechanics call it what it is!? It's an ENGINE! The heater has a motor. Combustion engines run on petroleum, heater motors run on electricity! The lead teacher of the automotive school I went to in 1969 told his classes. If you call this piece of equipment a motor, I will give you a F on your grade! Just sayin!😂

I like using synthetic MOTOR oil in my engines. Except for my motorcycles with wet clutches where I use 15W-40 diesel MOTOR oil.

Who cares? Call it whatever you want.
