I have heard the Honda Fit does not use a typical paddle shifted transmission. Can someone please explain how the Honda Fit transmission works vs. say an Audi double clutch type paddle shift transmission? What is the technical term for the paddle shifted operation of a GE9 auto transmission?


I have done some research into this but I was not able to determine exactly what type of transmission the 09 AT Fit uses.


It looks like this perhaps?

The Fit uses paddles all right - those are the things you use to invoke a manual upshift or downshift are they not? In that sense the Fit has paddle-shifters.

I understand your point though. In terms of what the paddles themselves are connected to (i.e. the oily bits you don't see in the transmission), there could be a number of things and technologies really:

1) a conventional torque-converter automatic transmission (e.g. the GE8 Fit)
2) a CVT, or continuously variable transmission (e.g. GD/GE Fits in other countries, the CY4A Mitsubishi Lancer)
3) a single-clutch sequential manual gearbox (e.g. WRC rally cars, F1 cars, motorcycles)
4) a single-clutch automated manual gearbox (e.g. Ferrari's road cars, BMW's Sequential M Gearbox)
5) a dual-clutch manual gearbox (e.g. Audi and VW cars, the Nissan R35 GT-R)

As for your question...
The GE8 has a conventional A/T hooked up to those paddles. Yes it's got paddle-shifters but those paddles control a garden-variety A/T. This combination has become quite common now actually. Basically any action on the paddles orders the A/T's brain to downshift or upshift accordingly - as long as the engine's safe from grenading itself due to over-revving, of course.

HTHs

 

^ you really know a lot, dude...

 

Bored a lot, more like.

Thanks

 

my thoughts exactly...

You have some good knowledge. Out of curiosity what kind of manual gear box is my GE8 manual transmission.

 

Just want to point out that the chassis code is GE8 and not GE9.

 

I think the GE8/9 is based on model year? I am not sure tbh. I thought GE/GD referred to generation and the number designation was based on model year.

Regarding the Auto transmission it seems that the function is based on driver input correct? In D mode it is a conventional torque-convertor automatic gear box but it seems that in S mode the operation changes to some sort of electric override mode? Considering that our beloved fit is an econobox at heart is it safe to assume that we do not have a f1 type gear box or a dual clutch gear box from german luxury vehicles?




Extending this question then, how would one upgrade the paddle shifting operation of a GE8/9 AT Honda Fit? Are there any upgrades available for this?

 

The 8 in GE8 refers to region not the year.

Does anyone know design-wise how today's Honda AT's differ from the Hondamatic transmissions I've read about which supposedly are like a MT with a very complicated automatic clutch system?

 

were hondamatics ever an actual clutch system? i thought they were just glorified slush boxes... ie: torque converter based.

 

You know, I really don't have a clue. I'm going off of something I *think* I remember reading about them. From what I've read in the last half hour it seems you're right.

 

It's a good ol' five-speed manual gearbox with synchromesh.

At least you lucky guys in the US have a GE8 M/T option. All the GE8s here in the Philippines are flappy-paddled A/Ts...only the smaller-engined GE6 gets the self-shifter and three pedals.

*wonders if an A/T-to-M/T GE8 tranny swap is possible*

 

A common observation with Hondas: The number after the chassis code denotes a certain engine+drivetrain combination for that particular chassis.

e.g.
GE6 = FWD, L13A engine
GE7 = 4WD, L13A engine (Japan only I think)
GE8 = FWD, L15A engine
GE9 = 4WD, L15A engine (Japan only I think)

Regarding your assumptions on the transmission: Yep you're spot on Fact of the matter is, the Fit is too cheap a car to lavish such technical extravagances on. Cheapest cars I know that have a true dual-clutch box are the VW Golf and Audi A3 (mechanical twins really)...and their glorified coupe cousins the Audi TT and VW Scirocco (Europe only).

As for upgrading: I'm not sure what you would want to upgrade the A/T for. Do you want it to handle more power from the engine? Do you want to speed its shifts up? Not much you can do to most A/Ts I'm afraid...correct me if I'm wrong

 

"Do you want it to handle more power from the engine? Do you want to speed its shifts up?"



Yes. =D


I had a thread going that asked something along these line but pretty much got ignored. Can you upgrade the tranny in an AT for better power handling and/or faster shifts?

 

We do not however have a Sport Navi MT anymore. =/


IDK some of the Philippine and Japanese models look cool, AWD and CVT's? I would be tempted.

 

Hmmm...

Short of replacing the A/T for a beefier one, I can't think of any mod to the stock A/T to improve power handling (e.g. you add boost to the L15A and worry about the transmission destroying itself due to excess torque). Stock A/Ts should be okay with mild boost though

Faster shifts...best I can think of is some sort of electronic tweak. Not sure if you should do it to the ECU or some other module, most probably to the part controlling the A/T programming

Basically I can't help you there, sorry

 

Synchromesh... that was the word... thank you.

Yeah, I waited 4 months for my GE8 MT with Navi/VSA... Looking back it was more than worth it. It sucks that you guys don't get the M/T's.

I found out that a AT-to-MT swap is possible, there is a shop owner who told me about it... They do it as long as you have the money. They also did a K20 swap, and then when that blew they did a K24. Great guy, unbelievable workmanship.

I guess if you can find a good shop in the Philippines you should be able to. You might have to import some parts from Japan or something and it will cost quite a bit, but it is possible.


I was browsing the Honda Japan site and I saw that model, I noticed it was only available in AT, the same thing with the Toyota Matrix 4WD (only AT).
Would you know if there's any reason why the 4WD have no MT option, does it have something to do with the 4WD?


Dude you really have some good knowledge... +reps!!!

 

Well I'm not interested because I don't actually own a GE (look at my signature)...I'm interested just because it might be possible I know a few GE8-owning friends here who would love having a self-shifter in their cars, and some people who ended up buying GE6s precisely because the Philippine GE8 has no M/T Cheap way of doing it would probably involve mating a GE6 M/T into a GE8, if fitment ain't a problem.

Honestly I wouldn't know bro...had you not brought it up, I never would have known the GE9 had A/Ts only! Thanks

 

The old Hondamatics from the '70s were not like a manual--they were planetary geartrains just like an ordinary automatic from GM, Ford, whatever. The difference was that the first-gen Hondamatic did not actually shift gears, unless you moved the lever.

Functionally the original Hondamatic wasn't much different from the transmission in a Model T, except that it used a lever instead of foot pedals.

 

duh.... I've met your Aibo before, I just totally forgot since we're in the GE forum.

Thank you for your great info.

I wonder why the 4WD only comes in AT, I think it must be something with the 4wd
