Default 80,000 mile service recommendations?

Good morning everyone,

was wondering if there is anything I should be aware of that should be done at 80k for my 2016 gs350 fsport rwd ideally to keep it running optimally. I did the plugs at 60k, brakes were around 55k. From what I’ve been told trans fluid at 100. Please let me know, I’d like to avoid taking it to the dealership and overpaying if all I need is an oil change.

thank you

Check coolant (they have strips to determine how "healthy" it is), replace if needed. Same for brake fluid.

We just got our GS450h recently, its a 2020 model with under 35k km or 21k miles.
I did the rear diff, several transmission spill and fill, replace brake fluids to Racing DOT 4 fluids (for their higher boiling point characteristics), engine oil and filter.
Wiper blades, air filters and activated cabin charcoal filter.
4 new summer sports tyres.
All up it cost me about $1600 AUD in parts and all done and took no more than 5hrs of my time. $1000.00 was for the tyres.

Our Xmas getaway was cut short due to massive flooding and road closures.

I wouldn't wait until 100k for trans fluid. No harm in replacing it now and again at 150k.

The car is either 8 or 9 years old. I would do the Brake fluid, Coolant, Trans and diff. Also do a spray in intake cleaning followed by the tank pour in cleaner. Those fluids unknown, are 8-9 years old also. Checking ph on coolant gives chemical ph, but does not tell how much contaminates are in that fluid that could deteriorate the coolant system parts and seals, and gaskets.

Find a good rated Toyota dealers at 40% of the Lexus cost. You also save money if you buy the fluids yourself and give them to them.
