This is normal operation conditions for the car in SPORT + MODE
My GSF when fully warmed up in the summer time does this.
If i go into manual mode sport plus and im doing 40mph in 4th it wont let me shift into 5th and thats cuz the ecu and tcu are programmed in such a way
if you are not at a certain speed it wont give you the next gear, to keep the car in best power band range.
If you want full control in manual mode drive in Sport mode and u can upshift to 7th if u wish at 45 mph.
As far as those of you having issues of the car not shifting when u pull the paddles and redlining make sure your at full operating oil temperature
before you go ripping it, that could by why the shifts are delayed.

OK, let me chime in here. I am going to share my thoughts mainly based on my experiences with my GS460 and now my GSF because I have noticed this now as well.
These cars are programmed in such a way that if for any reason, the stability control system kicks in ( it may kick in for no damn reason sometimes only because the system is triggered due to hard acceleration and sometimes sharp turns ).
If that happens, it is designed to hold gears as long as it deems necessary to avoid any loss of further traction between gear shifts and torque transfer. This is a common feature in our cars.
Basically, what I am trying to say is this:
If this happens to you more frequently than you're comfortable with? CHANGE TYRES!

Sport Plus mode is meant for the track and spirited driving, not toddling around town shifting as you please.
So yes, you are 100% correct. The car needs to be in it's appropriate power band at all times.

I will say after doing a full transmission flush and fill at 54k miles (Toyota dealer) my car seems to shift much better. Before I would frequently have problems where it would hold a gear way too long before upshifting or not “listen” to my up or downshift inputs at times. You do definitively have to have it warmed up for proper behavior, but even when it isn’t fully warmed up it still shifts better than before the flush. Glad I did it .

Kind of an old thread but I can give my 2 cents on what I've noticed with my 2016 car. Shifting in auto Sport mode is pretty relaxed at all times, upshifts will take their time unless you're above 4k in any gear. Downshifts tend to be very creamy and work well in for 2nd at 30, 3rd at 40, and so on. Anytime you're on an incline or encounter a turn during medium-hard acceleration the car will happily stay in its current gear and will ignore what you say even at high RPMs. Good for city driving 90% of the time.
Shifting to manual mode will change the behavior of the transmission to a noticeable degree. The relaxed upshifts now become more immediate the higher you are in the Rev range, with the occasional feeling of lambo single clutch. And downshifts lose all their creamyness and simply become sharp and instant with it being most noticeable above 4k. Trying to do any driving while being below 3k is pretty pointless and can be very jerky in low gears. That 2nd gear at 30 now needs to be done at 40 if you want it at its best.
Personally I'm not a big fan of sport + since it doesn't work too well on the street but it does give you a small boost to your shift speeds, mainly due to throttle response I feel.
