8 speed transmission
Is the Lexus 8 speed transmission different than Toyota? I though they would be the same. The reason that I am asking is because my wife has a 2018 Camry and you can put it in S mode and select a gear to be the limit, kind of like my old 2010 IS 6 speed. I can put her car in S4 and that will be maximum gear or S5 and 5th gear would be maximum gear. I do not know how to do this on my 2017 IS. Can we even do this? When I try, it just stays in that gear then goes back to drive. If I move over to M I have to physically down shift when needed.

So the issue is that it will stay in 5th if you select 5th, but not downshift to any other gear when you come to a stop? Or are you expecting it to automatically downshift if you slow down, then punch the gas again?

Yes. My old lexus and the 2018 camry would shift automatically. Say I had it in S4. The car would still automatically shift, but only between 1 through 4. The new IS does not have this feature. I guess the old lexus and the new Toyota have basically gear limiters, where as the new IS is closer to a true Manual.

- if engine speed drops too low, such as when decelerating,
- if engine speed reaches the redline,
- or when transmission fluid temperature gets too high.
I had a 2015 Camry for a while, and the S mode was really just a limiter as you stated. It will not maintain a high gear if you ask for more power.

They are different. The older IS, older GS, a lot of the FWD Lexus and SUV have the S mode or sequential mode. When you throw it into S mode, it will shift up to the max gear you select. It still acts like a automatic transmission where it will upshift and downshift on it's own.
The newer GS, IS, F lineup has the M mode or Manual mode where you have to shift up. It will do the downshift one it hits a certain speed but it won't upshift for you.

The 8 Speed Auto in the Camry is the Aisin AWF8F35 and the one in the 3IS is the Aisin AA81E. Very different as one is for RWD and one for FWD. The RWD version is a lot beefier and can handle more torque. It's used in slight variation, in the RCF, ISF, LS, IS.
The one in your Camry is also shared with:
2018 Buick Regal
2015 BMW 2 Series Active Tourer
2016 BMW X1
2016 Mini Clubman
Rav4/Camry
a bunch of Volvos

The difference is the software. Its the same transmission but Lexus uses "m" manual mode and Toyota uses "s" sport mode. The sport mode chooses the best gear for what your foot is doing. Manual is whatever gear it is in until you decide to change it. If I remember correctly the Camry XSE has manual mode instead of sport
