2017 Tahoe Low Milage Maintenance Recommendations

[Jason101]

I have a 2017 Tahoe LT with 46,000 miles. (Bought it new in 2018). The only thing I've really had done up to this point in 6.5 years of ownership is oil changes as my dealer hasn't recommended additional service. I was going to get the following done based on some threads I read here:

- Transmission Service ($300)
- Transfer Case ($200)
- Coolant Flush ($185)

Are any of these overkill right now with my milage and age? The maintenance schedule indicates I really only need the coollant flush. I used to tow a 6,000 pound travel trailer a few times a year, but haven't in the past 2 years, so I consider my usage "Normal" (vs Severe)

To be clear, I have done other stuff that I can on my own like Engine Air Filter, Cabin Filter, Tires, Battery, etc

I think its a good idea to have the fluids changed along with front and rear end fluids.

We got our 15 suburban over a year ago with 59k on it and the transfer case fluid did not look good and the fluid in the front diff looked horrible.

One thing I do, maybe seems useless, I suck the brake fluid out of the MC every couple years and refill with fluid from a sealed bottle. That fluid does get dark with moisture. Also do the same with the coolant, but with your 2017 the total coolant change is probably best.

Assuming any of those are 'overkill', isn't overkill better than underkill?
Any of those services gonna cost less next year?
The longer you want to keep it, the more overkill you apply to your vehicle service schedules.

No, your usage is severe service like the rest of us, especially since you used to tow with it.

Change your differential fluids when you do the transfer case. Mine feels like she's going in three different directions when the fluids in those are needin' a change.

If you have the 6-speed, get rid of the factory thermostat on the side of the transmission and get the lower temp unit.

Brake fluid flush and total replacement from sealed bottle(s) with correct D.O.T. specs every five years due to brake fluid's affinity for absorbing moisture.
