Any info on the automatic transmission?
 

I know that it's derived from the automatic in the IS-F, but I'd like to know the gearing and what kind of control we will have. What RPM is the stall? What is the torque capacity? Does it shift smooth and crisp, or like a typical slushbox?

My last 6 cars were manual so I don't know if I want another, it's starting to annoy me with clutches that wear out the second you up the power and tons of racing. Automatic guys are always faster once you tune them, plus it is so nice to just cruise without worrying about rev-matching.

All i could gather from recent reviews was that its not anything special.

Appreciate the reply, I guess we will have to wait for more information. I guess it will have paddle shifts?

Here's what we do know:

-Aisin made
-6 speed
-based on the IS-F
-paddle shift mounted on the wheel
-has a Sport mode and a Snow mode
-has a Manual mode (M on the shift gate)
-rev matched downshifts
-temporary manual mode (when you hit the downshift paddle in D)

if it indeed turns out to be a 6 speed version of the IS-F tranny, then it IS special.... VERY, VERY special....

AT haters gon hate... but i'll be enjoying my 0.1 sec shifts too much to care :lol:

Lotus uses a Camry 6 auto in the Evora, and just with software they apparently made it into a pretty damn good sports transmission.

Auto guys shouldn't worry. If they've taken lessons from the IS-F's and whatever Lotus did with the Camry's, it'll rock (for an auto...).

:clap:

Thank you sir, this information has confirmed it. I am getting the auto!

Enjoy your parasitic loss too. The IS-F can tolerate it because it has a V8 engine under the hood that produces quite a bit of torque. A transmission with a torque converter has no place in a car like this. A dual clutch setup is what should be used in the FRS.

in Inside Line review they say
"Eye on Driving Fun
There are disappointments, but they are minor. The six-speed manual is a touch notchy, and not quite as precise as an MX-5 shift, while the six-speed auto that is also on offer changes smoothly and quickly, but lacks the sharpness of its dual-clutch rivals. When it's on, the ESP also intervenes too harshly — the sound of it at work is so loud that you initially feel as if something has broken, and it scrubs out power delivery at an overly dramatic rate."
some small info on automatic trans

That fact Hyundai is using a dual clutch setup in an economy car but Toyota is still using a torque converter for their sports car is a damn shame.

Maybe bothering to put in an automatic at all was a requirement of their marketing department. If I were Toyota I would have spent virtually zero time dealing with the auto, just throw in whatever if I were forced to, otherwise it'd be manual only, as a sports car should be IMO.

I disagree, a high end multi clutch setup like the PDK transmission is superior to the traditional manual transmission in every way. Plus the transmission can be used to replace the slush boxes in other Toyota models which would mean better fuel economy for the entire brand.

dual clutches are overrated. there are tons of problems that go along with them. just look at all the problems the M3 had in the beginning. AT with torque converters are making a comeback. 8 sp is the new 6 sp. manuals and DCT's cant touch that just yet. and ZF has a 9 sp in the works.

parasitic loss? there are ways to minimize that, just look at mazda's new skyactiv AT. small torque converter with full TC lock up early and often. nobody knows the details of the FT's AT yet, but if it is based on the IS-F's 8 sp, then there will be TC lock up from 2nd gear on. and 1st gear? yeah the TC "slips" like a slushbox, but guess what? it also creates torque multiplication in the gear you need it most.

and last but not least, when your fancy DCT craps out, and you're out of warranty. good luck with the $10k bill because most if not all of these trannies are NOT serviceable and can only be replaced with a new one... Me and my crappy AT based off a known platform used in multiple cars for years? i can source enough parts to build another one from scratch...

like i said, AT haters gon hate. if you have nothing to add, move along. your insults fall on deaf ears...

Which review said it has a snow mode? I think I read somewhere that it's great in the snow but I don't remember reading about specific snow mode. If it does have one that might be useful cause of the snow we get up here.

there is a Sport and Snow button aft of the AT shifter, but it's missing on the MT shifter.

Except for driver enjoyment. I've driven many dual clutch setups and none of them provided the enjoyment of actually having to change gears like a manual.

There's no doubt that the manual is a slower solution, but I couldn't care less about numbers.

Drivers with a MT don't need the transmission to let us drive in the snow.

Sorry, I had to :)

We could argue all day about the benefits vs disadvantages of both transmission. At the end of the day, it's all preference.

No but the TC and VSC will definitely talk to you if you start to shift a little to hard. ;)

So because you prefer an old school manual Toyota should just say fuck it and use ancient technology for an automatic? A dual clutch system should be used in every Toyota car that is an automatic. Like I said it is a sad day when Hyundai is outpacing both Honda and Toyota.

Just because it's newer doesn't mean it's better. Hydraulic coupling has a few advantages; higher efficiency when input/output speed is not the same, aka less energy lost to starts, and theoretically less servicing required because there is nothing that is supposed to wear out.

A single clutch gearbox, torque converter or not, can shift much faster than a manual transmission. I think most people consider that adequate for a typical car, and hence there is no reason to use a more complex and expensive dual clutch system, especially considering that clutch plates inevitably wear out.

^ Bingo. Some of you people really need to learn a bit more in-depth on stuff before making statements.

With Torque Convertor Lockup like it's controlled in most cars today, there is just as little drivetrain efficiency loss as a manual. If you're comparing the auto in the FT to one in say, a 90's or early 2000's car, then you're comparing it to the wrong transmission. As other's have mentioned, the IS-F's auto tranny can shift in 0.1 seconds, much faster than all manuals (bar the sequential ones used in racing). Also, after first gear the TC is locked up right up until 8th (on the IS-F), meaning you get just as much throttle response and efficiency as a manual. I'd be more worried about the accelerator lag from Drive-By-Wire than I would be about the responsiveness of a modern TC'ed auto.

DCT's are reasonably new technology for a production car, and not something I think Toyota should be trying in what's supposed to be an "affordable", reliable, fun car.

Does the IS-F auto handle added power and track use well? I would be a little worried about heat...

Yeah, from that FR-S unveiling yesterday, I highly doubt the auto transmission is going to be from the IS-F now. I guess I'm just gonna have to buy it as an manual and hope it doesn't blow up in the process of me learning how to drive it.

You had x-ray vision? o_O

For a sports car I absolutely do, but then I've never been about the numbers sooo.. :shrug:

And Dual clutch systems are becoming less important with the newer autos. For autos, they are good. Both completely lack the feel of the manual IMO so both will be avoided by me at all costs.

They keep using words like "based on" but they don't define it beyond that. It's not going to be an IS-F trans limited to 6 gears only I'm sure. I'd bet it's a different trans all together just with similar computer tuning.

why not? the IS-F tranny isnt some magical AT. at its core, the ISF 8 speed just uses better solenoids to control the hydraulic pressure to allow lighting quick shifts. combined with the aforementioned TC lockup strategy, you get an incredibly quick shifting and responsive AT. the old school musclecar guys have been building AT's for decades. this is nothing really all that new, except for the fact that lexus had the balls to do it on a production car.

If they are going down the path of car enthusiast and keeping the cost low then why not? Adding an highly sophisticated automatic transmission will not only add price to an affordable car, but would also be a waste of time because car enthusiast out there will never get and automatic.

Not to mention the first drives of the automatic weren't exactly glowing. They weren't bad either, but I don't recall any great words of praise..

interesting infos!

thanks for that!

I am not a fan of AT but I will test drive this for sure?!

OT: is it possible to drift with AT?! :D I can´t imagine it!
