This one would be a great candidate. I’ve already seen a few pop up over 50,000 miles with a valley plate leak on Facebook. But it’s a small sample size right now.

Yeah true, but looking at the carfax report (missing maintenance history for such a big gap) as well as so much mileage being put up in a year feels like it’s too much risk.

There's no service interval for the TVD or transmission. Why are you guys changing the fluids? Someone told you it's a good idea? I have proof WS fluid with over 120k miles and 5 track weekends is still viable fluid from Blackstone Labs.

I can't imagine why the TVD would need a fluid change under 200k miles. There's no magic going on there at all.

If Lexus has anything close to an Achilles heel - it's their transmissions/diffs. I'm not eager to save $60 on a TVD drain/fill on a $20,000 diff without warranty (2016 GSF). If the "lifetime" of the fluid is 100,000 miles, that's based on a failure rate and I'd like to stay away from that threshold. I'm not so much worried about degraded fluid as I am the metal particles.

Are you local? Why not take it to Lexus for a PPI? A couple of hundred dollars won’t matter especially If you’re that interested you can probably use the results of the PPI to get some more cash off the sale price.

Blackstone said I was still good from a viscosity/lubricity perspective at 120k miles in my transmission. I did a 50% fluid change at ~156k miles by dropping the pan, replacing the filter and refilling with about 5.5 quarts in a system with ~11 quarts in it.

The TVD only has a couple of wet clutches in it. Not much to wear but friction plates and drive plates, and if they do wear, they just help the remaining fluid stay grippy. I'm not even slightly worried about it. I've worked on LOTS of wet clutches when I was doing bike stuff.

I remember watching a YouTube video where someone was changing the TVD and transmission fluid because it looked "dirty". The car had something like 30k miles and the car never saw the track. The logic was that since it didn't look red that it was bad and that is further from the truth.

Toyota and Lexus have a reputation for longevity and I trust that the engineers know what they are talking about.

I have a 2019 Tacoma and it recommends oil changes every 10k miles and I've had backyard mechanics tell me that engineers don't know crap and that I should change it every 3k miles like other cars do...

I respect the engineers know much more than I do - but I follow their lawsuits. If there’s anything to maintain prematurely it’s their transmissions. The Tacoma is a great example of their transmission shortcomings.

So what’s the status? Any word on service hx for those 90k miles?

I would highly recommend taking the car to a Lexus dealership with a good reputation for a full Fidelity inspection prior to purchasing the car. Is this a mom & pop dealer? Do they have a return policy? I purchased my GSF with 62k miles, but the selling dealer (non-Lexus) had a good reputation for used car sales (sold many a luxury and exotic car) and had a good 3-day return policy. Upon purchase, I took it immediately to Lexus for a full inspection. The mechanic spent several hours going through everything — it was money well spent.

F cars hold up surprisingly well — even when being tracked often — especially against its German counterparts, but you can’t be too cautious when plopping down over 30 grand.

Good to see you back, Tom. Still considering the GSF?
