Hallo again...newbie here ...:
My 2007 RR Supercharged has 83k miles and no service records!
I know it had oil change and that's about it.
Should I have the differential and transfer gearbox fluids changed?
What about the auto transmission...10 years?


Cheers

 

It's cheap insurance to change the diff and transfer case fluids. You can DIY without too much difficulty if you can change engine oil okay.

Auto box fluid probably could wait until 100K unless you have issues at the moment.

 

Thank you.

 

Personally, I'd change ALL of the fluids. Even if the mileage isn't there yet, it's 7 years old. Even the dexcool in the radiator is only good for 5.
