Question about A/T using it in Manual mode

[Oburn]

Maybe this is more so for guys who drive the A/T version of the BRZ or maybe someone in general would know.

This is the first car I've driven that's A/T with the option to manual and shift and its how I prefer to drive. I never fully learned how to drive standard but I may learn eventually and do so with my next car.

That being said, my question is, when shifting in Manual mode, will shifting while giving the car gas wear out or hurt the car or are you supposed to let off on the gas as you shift?

Also I know sport mode makes the car rev higher but does sport mode do anything for the car when driving in manual mode or no?

I drive using the stick to shift btw, I'm not really a fan of the pedal shifters, I drive with 1 hand on the wheel.

Any info I appreciate and please, if your just gonna comment that I'm an idiot because I have an A/T for a sports car don't bother, it was the choice I made and I'm happy with it.

Theoretically it's actually better for the transmission to keep on the gas when you shift, at least at higher RPMs. It keeps the line pressure up in the transmission so the clutchpack engagement is faster and doesn't generate as much heat.

Sports mode under D mode = Holds gears longer during acceleration, less shifting up. Shift faster. During hard brakes like a corner will result in a downshift same time it holds the gear to let you power out a turn. Manual mode allows you to shift when you choose to shift unless you come to a stop and the engine will prevent it from stalling and change gears by itself.

I put mine in manual and sports mode along with the aids on (used to keep it off but I had a full sideway glide which was fun but dangerous hahaha ahem) I'm not to osure about manual and sports mode I haven't tried manual driving during canyon I'll do it next time and come back with a review. The rev match is awesome downshifting. I hope I helped you out. Peace

Oh ok I wasn't sure because I was always keeping on the gas when shifting but sometimes I could smell a burn smell wasn't sure if maybe I should be doing that. Last few days I was trying shifting while briefly letting off the gas but it doesn't feel smooth. I'll go back to shifting while keeping on the gas.

Yeah I notice it downshifts on its own but I normally do it myself but is it better on the engine if I let it downshift on its own?

So you keep yours in manual and sports mode? Does the sport do anything with manual mode on or does it just benefit in "D"?

I'd like to add that I was surprised to learn that hitting a paddle accidentally while turning the wheel or signaling (not sure how I did it) and in DRIVE will still shift. I downshifted in D when I hit the "-" paddle during a tight turn, at least that's what I think happened. I thought that the paddles wouldn't work unless in MANUAL mode, but apparently mine do.

Scared the crap out of me, and I pulled over to figure out why the engine was racing. Sorry to digress. Back on topic.

Yeah it still works in D mode, and it's able to do it as low as you want to go. But I think most cars with paddle shifters allow that and this isn't something that's just on the BRZ.

When you tap them while your in D mode, they go temporarily manual. It allows for passing cars on the highway to be a little easier. Goes back to D mode after a couple seconds

The Sport does nothing in manual mode since you control when you shift. It just does not turn off the light such as when you hit cruise control in sport.

As for downshifting, you do not really NEED to downshift because the transmission will down shift before it stalls. However I always downshift (just feels better) and you will not hurt the car if you downshift yourself at a reasonable RPM range which you can feel and hear when that is necessary. I will admit I have forgotten I was driving in Manual mode and took off from a few lights without shifting. I also prefer to use the stick and not the paddles the majority of the time.

Yeah I downshift on my own but I find going from 3 to 2 and 2 to 1 sometimes I don't do it as smoothy, more so from 2nd to 1st it's usually 50/50 if it downshifts smoothly or not lol.

Yeah I tried the paddle shifters they are cool but I'm a 1 hand on the wheel mind of guy and turning while trying to use the damn pedal shifters I can't get used too it so I stay with the stick.

Btw I know 0-60 on the standard out bets the A/T, can't remember by how much. But how much more of a difference would it be between standard and a A/T in Manual mode?

Lol nothing to be scared of, its setup purposely that way its too bad this isn't underlined more, if you hit the paddles in drive it will still shift the gear. I guess its for if you believe the transmission picked the wrong gear you can slap it over to the correct one. Toyota was determined to make an automatic gearbox that isn't boring or a slush box so they give you the ability to correct it if it picks incorrectly.

manual mode, isn't true manual control, the "computer" is going to take control if you start to reach a dangerous limit. Sport mode does actually have an effect on the manual mode, its allows you to hold the revs longer than if you just had it in regular mode and manual. PS, you can also leave it in auto mode and take over gear changes with the paddles. it won't be the same dynamic as in manual or sport manual, but it is handy to control shifts. I think i do this literally every day i drive it.

The manual is 0-60 mph 6.2 second, and the automatic is 7.9 seconds, in manual mode it will be the same if not worse. its 1.7 seconds. It has nothing to do with when it shifts the automatic is geared much more for fuel economy than acceleration or top speed. Plus if I remember correctly the automatic adds 200+ lbs of weight to the car, you would need more power (headers exhaust intake tune lightened flywheel etc.) and a bit more grip from better tires to be able to equal or surpass the manual FR-S 0-60 time.

Oh ok, yeah I got the stealth black Perrin cat back exhaust resonated 2.5 inch, and rev works Uel header right now. Getting Perrin CAI installed on Tuesday. Next ill be getting the ecu tech tune. Thx for the info
