Toyota could definitely learn a trick or two from BMW, who uses the same Aisin 8 speed in X1/Mini models but have added launch control, anti-lag farts on upshifts, and consistently smooth downshifts on braking/no throttle.
RE: TSS, I've daily'd the RAV4, Corolla, and Camry with AEB set to High on all. Haven't noticed any weird braking triggers despite driving aggressively (unlike FCA and VW systems). Toyota system's steering assist is also weaker since it's a 'reactive' system as opposed to Honda's 'active' system. It's built into the badge only on some older models, but also relies on camera array on windshield for auto high beam and lane departure assist.

Don't know if it's the same 8spd Aisin for the IS200t/300. Haven't noticed the trans shift jerky when cold as it's always smooth, but there are times when it's super jerky during downshifts. I think the mechanicals itself are fine, but Toyota really needs to get their TCU tuning sorted out, in conjunction with its throttle mapping. It's always super slow to respond to downshifts even when I nail the throttle in sport mode. This is even after JB4 base map as well. It's a stark reminder that the motor/trans is ultimately tuned for maximum efficiency. I'm sure the JB4 pedalbox could help but meh.
I would assume Lexus uses the same/similar version of TSS, but I've found it mostly flawless in the 6mons or so I've had the car. Adaptive cruise is also great. Don't know if TSS is further refined on the Lexus vehicles vs Toyotas. I've never experienced the autobrake function (gf has and saved her once), but collision warning false alarms are few and far between, vs the old Mercedes collision system which was terrible in the B250.
