Manual Trans gearing for 2017 model ?
 

I've read the differential gearing has been changed from 4.1 to 4.3

I've read that 6th gear has been strengthened.

I've read that overall mileage figures are lower than older models.

I cannot find anything about gear ratio changes within the manual six speed transmission.

Certainly sixth gear must have been changed to allow for not too high revs at freeway speeds and above.


Anyone have info on actual gear ratio changes ?

Googled this just now:

I don't remember reading about a ratio change in the official Toyota documentation. I believe it's still 0.767.

Gear ratios are the same. You just run a bit more rpm at highway speeds, its not a huge jump.

So two shifts to 60mph now. You can just barely hit 60 slightly past redline with the 4.10s

How did cars.com get the gearing specs but they're not on Toyota or Subaru's website?
I tried searching for the gearing

Well I guess my real concern was not for tracking, but how high my engine might rev at very high freeway speeds (causing poorer mpg). In the northwestern inland states and portions of west Texas speed limit can be 80mph...and of course, that means running 90mph or so in reality. Possibly Toyota and Subaru did not consider this. So I'm ready for a 7 speed as in Porsche and Corvette...if 6th gear ratio has not changed since 2016 models/combined with the now (for 2017) 4.3 diff.

Or just do unexpected mod .. of installing 4.1 diff :D if you prefer older year ratios and mpg / rpms @ high speed are more important then acceleration.

Just swap with someone with a older MY or an AT, there won't be a shortage of takers. You should even be able to get the other party to do all the work. The gearing on the MT is fairly short anyway so you won't be losing much either way. Take pity on the MY17 AT owners who got exactly nothing as an upgrade.

.. hmm, on second thought, this is first time i heard of different MY2017 gearing .. and starting to think, if THIS might be the reason why bigger performance numbers are cited for new MT & not for AT, with no actual performance affecting changes to engine/ecu tune/etc? Otherwise why else AT would have no gains/improvements, it sounds illogical :/

No, it's because of new engine parts including both manifolds

I am sure they thought of this... it will be fine, you are worrying too much. Gas mileage is more about throttle position than revs, as long as you stay light on the throttle it won't be a big issue. They also made a bunch of engine changes remember, maybe some were to handle the slightly higher highway revs.

As someone that used to have an S2000 with 4.56 gears that thing would be at 5k+ cruising on the highway, it wasn't a problem and still got decent gas mileage.

Gears don't provide more horsepower, just increased mechanical acceleration. Dyno pulls are generally done at the closest ratio to 1:1

I don't know if you've found the information but in case you need something from Toyota, this PDF link is active currently... And it is 4.30 for the manual only.
