Guess I'm no longer driving a GMC Suburban K3500 anymore...ever since changed out the OEM steel wheels to Alcoa Forged Alloy's....or that did not buy new tires from GM but Michelin & now Bridgestone and they are NOT the OEM size...or that my fuel filter is not Delco...or that my air filter is not Delco...or that my radiator is an after market (can't remember the OEM of that thing)...or that my fan clutch is no longer Delco, but TRW...or that my automatic door lock motors are no longer Delco...etc, etc, etc, etc...
Oh for that matter...just about everyone out there who has replaced their components with non-OEM no longer drive the OEM vehicle that left the factory with....
And that you have tuned the computer...it is no longer OEM, so what does that say about your vehicle...
Yes, best toss the glove box manual and if you bought the shop manuals...toss them too...ditto for any Internet search for info...it no longer applies to 'your' vehicle 'cuz 'you' changed some components on it....

Who warrants my new gears? GM or the gear manufacturer? I'm running what is required to maintain the warranty on the new gears.

Not running synthetic gear oil goes against what the manufacturer recommends. The Purple Grape Juice is Full synthetic, and right from your owners manual GM recommends: GM wrote:
