This is direct from my Lexus tech.
"In twenty four years, you know how many problems I’ve seen on rear wheel drive transmissions other than electrical stuff like solenoids or ECUs? None. Zero. They just don’t break, no matter how much the owner abuses them. Front wheel drive transaxles are a different story. Anyway, if you’re going to change fluid, I would say to do it regularly. A drain and fill is only going to change maybe three quarts of fluid. I checked, your tranny holds 10.6 quarts. One drain and fill every few years probably doesn’t do much of anything. The main problem with a drain and fill on your car is putting the proper amount back in. There’s no dipstick, so it can be tricky. You can’t properly check fluid level without a scan tool.
Don’t get me wrong, it’s never a bad idea to change fluids, but I think tranny fluid at 30-40k is a bit extreme. We don’t even start to recommend it before 75k.
Speaking of which, I think the diff fluid is more important to change frequently than the tranny fluid, especially the front one. I have seen some nasty fluid come out of the front diff at 30k. For whatever reason, the rear doesn’t get as nasty. Lexus doesn’t call for it that frequently, but like I said , it gets nastier than you might think."
So, for me at least, I'm having the front diff fluid changed at 30K for sure, and probably the rear as well.

does the 2l rwd 8-speed have a front diff as well or only a rear diff? does anyone know? i just had the trans fluid as well as the rear diff fluid replaced by a lexus dealership at my request but i didn't mention the front diff because i thought perhaps only awd models had a front diff. maybe it does, though? @arentz07 , any idea?

edit: Or in the case of my former GTI, I had the front differential fluid replaced. There was no rear diff. Make sense?

Since the car is more RWD biased, I changed my rear diff at 30k miles and front diff recently at 65k miles. Will do rear diff again soon

Transmission fluid just hit 99k never change since I have lifetime powertrain warranty as long the car is up to day on service like
oil change rear diff, and etc. the warranty say go by what Lexus say leave it. Why waste money.
I just leave mine no point if it’s covered.
my old ES I never change the fluid sold it at 275k back in 2017 and the person I sold it to was my cousin and right the car is 370k all he did oil change and gas up. Still running today
