I know how your feeling......My wife told me "if you spend another 20k modding a brand new car Im outta here". I said "yes dear.........Feed the dogs on your way out huh".iamdiceman said:I asked the dealer where I bought my car if it was alright for me to change the DIFF and transmission Fluid.
And he said no we will void the warranty if you dont use GM fluids.
Then i asked if i could use RP in the engine and he said he heard it was good oil so fine, But if my dealer is so goofy about after market fluids i can imagine the heart attack he would have over a CAI or headers.
So, mine is just stock, I dont need my wife b****ing at me if I break something and the warranty gets Voided.
But heck In a couple years when the warranty time is up.. Look out 11's !!
Also, this is part of a disclosure statement that the dealers are supposed to have customers sign if they (the dealer) have put anything aftermarket on a vehicle:Aftermarket Engine Performance Enhancement Products and Modifications
Some aftermarket engine performance products and modifications promise a way to increase the horsepower and torque levels of a vehicle’s powertrain. The products may have detrimental effects on the performance and life of the engine, exhaust, emission system, transmission, and drivetrain. The Duramax Diesel Engine, Allison Automatic Transmission and drivetrain have been designed and built to offer industry leading durability and performance in the most demanding applications. Engine power enhancement products may enable the engine to operate at horsepower and torque levels that could damage, create failure, or reduce the life of the engine, engine emission system, transmission and drivetrain. Damage, failure, or reduced life of the engine, transmission emission system, drivetrain or other vehicle components caused by aftermarket engine performance enhancement products or modifications may not be covered under the vehicle warranty or GMPP plan.
