Re: New To Me '03 Tahoe

GU6 is a 3.42 rear axle ratio.
G65 is self leveling shocks, sorry no Posi traction.
You can search you tube for a vid on how to reset oil change light. I don't have my 800 series truck any more, I think you turn on the key and pump the gas pedal 3 or 5 times till the oil change light flashes.
