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.

Talked to my friend, who had similar frustrations with his Ferrari(!!)

He said the "Paddles only give you a vote on which gear you will get"

Agree, especially on the highway.

20 minutes doesn't usually make full temp for the oil if it is 45F or below, but 20 minutes should be enough to have everything working properly and not restricted by the ECM.

Lol. That’s a good way to put it

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!
This makes sense as it’s been happening to me more recently. Under harder braking in Sport+ & manual mode during spirited hard driving (after being warmed up), I notice it will not want to downshift & ignores my paddle. This is not when the rpm is too high when the car will beep. I’ll be coming to a stop while braking going through the gears & will seem to ignore 3rd down to 2nd initially. This has also happened from 4th to 3rd. It can be very annoying when the car won’t downshift. Zero issues with up shifting. Only downshifting during heavy braking is when I have the issue.

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.

Lol I will say I do fall victim to driving in manual sport+ a ton whether it’s the highway (spirited) or driving the car spirited to pickup milk. Understand should not use it all the time lol, it’s a bit addictive. But even in full spirited driving, the paddle shift not downshifting could that be solved with Toyota tech stream?

Not downshifting? Are you sure you're not in high RPM already?

Yep because if I’m in too high of RPM already the car will notify me & beep. This is when I’m in the mid range trying to downshift. No beep. Just doesn’t do it

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 .

This is a well known issue when the fluid level is low, even just a little bit.

Right. I’m thinking the improvement is more from a proper fill vs new fluid.

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.
