I can see the engine in the 300 and the 400 lasting any where from 300k to the apocalypse, they are extremely reliable, but the transmission... not so much. I really dont like the tranny in my gs and my dad's LX dropped a tranny before the warranty went out, phew, but lexus seems to have gotten their stuff togther now. Except for the whole 8 gears is way too many in an ISF thing but thats another thread

if maintained properly, you should easily get 250-300k out of it before a rebuild is required, if not more.

Transmission, if you install a cooler it will extend the life but the a650(e) transmissions are usually good for 200k or so before needing a rebuild, again with proper maintenance they will last longer

I rebuild a bunch of these for performance purposes. When I tear down a stock engine and transmission for cores to use, usually most at 150k miles range. The cylinder walls still have crosshatches, the engine bearings are pretty much as smooth as the day they left the factory, and everything is still in spec. I don't see why these things can't easily go 2-3x more that amount of miles without even breaking a sweat. In the transmission, the latest one I tore down had 186k miles on it and the clutch packs still had the original print readable! I'm talking about the part numbers they print on the face of the clutches, yes on the part of the clutches wearing and making contact. After 186k miles, the numbers are still readable and this transmission was not very well taken care of either! My guess is that a car that has had on time maintenance on everything will easily last 300k+ and probably 500k and beyond.

It has no filter. There is a very fine screen and that's about all.

Bought my 99 gs 400 in 2000 with 12k and now have 272k. I'm actually looking at changing motor and tranny mounts since it's still orginal.
