Transmission not rev matching from third to second
I noticed that when downshifting my is350 2015 RWD f sport (8speed tranny in sport+, manual mode), it would rev match all downshifts except from 3 -> 2. Is that something that is350 RWD owners here experienced too?
As you know, I have an IS 300 AWD but wanted to bump this because I am really curious about this. In my AWD, the 4-3 shift is not rev-matched either - unless I am heavily braking. 3-2 is always perfectly rev-matched.
Even in Drive mode it's the rougher shift point, especially in Sport mode. There are numerous threads about 2nd and 3rd gear shifting behavior, but not so much about manual mode rev match.
But yeah it's always been like that and others have reported same or similar.
I think most ppl don’t realize how high the rpm’s have to be for the electronic rev matching to occur, so they think it’s not working/works poorly.
Also their was definitely a TCU reflash around 2015-2016 because some swear they can bounce it off the redline without it upshifting and others swear they can’t. I’ve also seen a lot of back and forth between owners saying they’re transmissions do something that another owner will claim doesn’t.
I can confirm I can downshift rev match all gears assuming I’m meeting the above mentioned prerequisites. I can also take car about 100 rpm PAST the redline indicator on the tach and it will not upshift, some have said they can’t.

my 2015 350 awd Fsport rev matches every gear assuming manual mode, sport or sport+ and the rpm’s have to be very high, around 5k rpm for it to work. I think most ppl don’t realize how high the rpm’s have to be for the electronic rev matching to occur, so they think it’s not working/works poorly.

The production changed during 14 actually on the ability to bounce of the limiter. I remember looking up production month on mine to confirm, as mind does not and shifts up automatically.
My 16 200T behaves the same way @NickCaesar explained it. My car will rev match any gear as long as the revs are high enough. If the revs are not high enough it’ll downshift but will be really jerky. And I can bounce off rev limiter as long as I have traction control fully disabled. Might be different for you guys though because of the 6 speed in the AWDs

hmm you may have a point. Never noticed at ~5k not rev matching. But it does it on the other gears at low rpm.

I just find it odd. Most other cars I've driven will rev-match no matter what. BMW? Rev-matches every time. GTI with DSG? Perfect rev match. PDK? Of course it rev-matches. But for some reason, a few Toyota/Lexus cars I've driven are inconsistent.
I found that it will rev-match if I am heavy braking. Like, 70% or more brake pressure. So, I am reading this as: "manual mode is for spirited driving only".
Now I will say, again, downshifting into second gear ALWAYS rev-matches appropriately in my car. No idea why third should be different.

I've noticed the same. Under 30 mph, I can't get a rev matched downshift from 3->2. I've managed to squeeze a rev matched downshift at 29mph a few times. I wonder if it has something to do with the torque converter lockup? I know the lockup happens above 17-18 mph from my experience.

All those transmissions you named are simply superior. In every way.
I can only talk about my 6 speed since I’m awd, but it’s not a great tranny performance wise, not even really a decent one even. Just barely acceptable as an entry level performer.
Lexus chooses reliability over performance and ultimately the brand suffers because even the “f sport” models are lacking seriously in performance. I’ve even heard people say the GSF needs more power.
I love Lexus, but my next car which I plan on getting in 1-2 years is going to be a true performer and tbh I know I’ll miss the reliability but you gotta pay to play and I need something faster.
