I have a 2017 corvette with 4,000 miles on it. I only put 1,000 miles on it per year.
Based on time, when should I change my transmission and cooling fluids?

 

Welcome to these forums. Change intervals, that is a very good question and everyone you talk to will give a different answer most of the time. There are a lot 0f factors involved,how it's stored and humidity levels. One recommended if using synthetic to change engine oil one a year, more often when using nonsynthetic oil and replace oil before it's stored. Other fluids like Coolant every 2-3 years regardless of mileage. Brake fluid change every 2 years to prevent moisture buildup. Transmission fluid is recommended every 30K to 60K or every 2 to 3 years, this is one opinion from one person. Differential fluid change between 30K and 50K unless your owners manual says different, that's kinda a standard rule. It's your choice. One vechicle I have is a Chevy 2022 Silverado 2500HD 4WD with 34K miles and by 50K miles the dealer wants to replace all fluids at a tune of $3k. I might start with one thing a visit, we will see how it goes. You can contact the maker of these fluids and see what they recommend for range intervals in your situation, You should be able to stretch that out a ways.

 

This is very helpful. Thank you

 

Years back we changed fluids when it looked bad or smelled bad 100K miles or ten years. Not so much anymore. If it's off warranty I's pretty much your call. To me if oils looked nasty I changed it regardless of duration or extended life oils.

 

Thanks, I can’t wait to hear what my dealer says this spring!

 

I'm sure they want to sell you something, make them convince you that you need some kind of service. It would be very interesting to know how Jay Leno deals with his fleet of machines.

 

Thanks for the advice
