Lexus 8-speed conventional automatic transmission
Clarification: Which model?
Es350
It’s the same 8-speed AT that is in the Toyota Camry (Lexus ES built on same platform) and other new Toyota’s (Avalon, RAV4, Highlander, etc). Jury is out on long term reliability/durability of this transmission. Also see below:

Not really… this transmission was used on Volvo and I have recently posted what models last how long 👀
generally
AWF8F35 is the weakest at about 125k miles
AWF8F45 is about 150k miles
AWF8G45 is about 175k miles. (AWD only)
@Dan those are average numbers, if I am not mistaken. Let’s see how the ones in the United States hold up over time. We only got those here in 2018, which means other countries and vehicles were guinea pigs overseas before we got it here.
In general Toyota makes some very good automatics but they do not and never will sell them in the US.
The 8 speed is not one of them - those are just engineered to fail. By far some of the worst junk I’ve seen.
@Dan I guess we will find out over here over the course of time.
We will see.
Keep in mind that, Changing the filter requires dropping it out and an almost full disassembly - so considering how far Toyota went into making it impossible to maintain/repair, I wouldn’t get my hopes up at all…

(This isn’t the 81, it the previous gen 80 but as far as I remember they haven’t changed much)
@Dan what transmission fluid change interval (drain and fill) would you recommend for this 8-speed?
It depends. According to the manufacturer isn’t anywhere from 50k to 75k but I’d personally would do it at least every 30k miles (it’s about 6.5L~7.5L but luckily Toyota ATF WS is cheap)
