Hello I’m having a similar problem with my 2014 Chevrolet Silverado 2500 4x4, 6.0L whining when idling in Drive, reverse, and manual mode. It’s only been doing this for about a week and yesterday it started shifting like a midget driving a dump truck… anyway, the fluid level is kinda high In my opinion and the fluid consistency is normal/average. I know a little bit about the world of mechanics so changing the torque converter seems irrelevant. I’ve tried to do some research to find out if this is a CVT type transmission, but I can’t find anything on it. I’m only saying that because I know CVT type transmission has an internal belt and the whining sound, sounds an awful lot like a belt, either slipping or freezing up on a pulley. But I never owned a vehicle with a CVT type transmission and I’ve definitely never heard the whining sound coming from any transmission ever. My wife wanted me to sell my Ford 7.3 L diesel and get this truck because the Ford was too loud. So please somebody help before I start rubbing it in that I should’ve kept the ford.. Only bring myself misery Because she will put me in the doghouse, but I won’t be able to help myself lol
