Six Speed in a 6GC Options

[Kadett]

Does anyone have the gear ratios and final drive ratios of the 5S-FE 5 Speed and the E153 transmissions handy for comparison??

here you go,

s54: 3.285, 1.960, 1.322, 1.028, 0.820 / FD: 3.944, 4.176
e153: 3.230, 1.913, 1.258, 0.918, 0.731 / FD: 3.933, 4.285

the final drive ratio differed based on application, the bold are 6gc (i think) and mr2 sw20 turbo.

US spec GT have the 4.176 Final Drive
EU/JDM spec GT (3S-GE) have the 3.944 Final Drive.

The 7th gen gearbox is really weak and cant sustain to much horsepower. Going to 250 bhp is already pushing it. Getting a LSD + Radials with 250 bhp = bye bye tranny.

With my car I drive 75 mph @ 3200-3300 rpm.
On the 7th gen it would be 2800 rpm. Friend of mine got one.

For gas consumption it would be benifitial but in terms of power you would be better of with the GT or MR2T tranny. Best option would be the GT4 gearbox converted to 2WD but I only know of 2-3 cases that have succesfully done this.

Theorotical top speed of my car with a 225/40/18 tyre would be 160-163 mph. I speed that I will never reach or want to reach with my Celica because its not meant for it (2wd plateau, different weight balance etc etc)

like i already said someone needs to take the OEM gear ratio #s outta an E153 or S54 (both would be nice) and start talking to a shop that cuts gears..and discuss about making LONGER gear ratios..in theory it should be a bolt in application and all you need to do is swap out your gears in the existing bell housing (yes this has been done before)
i'm not sure if you could fit a 6th gear...but lengthening gears 2-5 is doable probably at the cost of a few hundred dollars

man whata mess that would be honestly....

It would be nice if they made the s series trans in a 6th gear. The damn gearing is so short a 3sgte swapped celica with a s trans doesnt make it real good economy wise when your crusing around on the highway at 4k rpms.. compares to when I swapped he e153 I was at 65mph in 2500-2700 rpms

Could you put the e153 5th gear in the ST's C52 tranny or would that cause problems with the synchro?

Would you need to make a custom synhro?

Would love to get the revs down for highway driving.

You may be able to tell that I don't know a lot, just what I want to do

[mandrek]

im quite curiouse about this too.. is it not posible to just swap out the fith gear??

The thought of a 6th gear is more for fun, but if I could have gears 2-5 lengthened then I would be content!

Anybody know if you would need a custom synchro if you changed 5th gear?

Is the shaft the same size on c52 and e153?

What about .706 4th gear from the GT Auto transmission? Could this be used for 5th gear in a manual?

Any OEM toyota 5th gears that come under the .713 e153 5th, or .706 GT Auto 4th gear?

The e153 gear would drop the RPMs by 375, which is a good start, a 600 RPM drop would be ideal (engine gets loud after 2800 RPM).


The ST has so much potential for gas mileage, it's just hampered by the gearing (which I believe was designed for Japanese highways, with a 60MPH speed limit).

I am also interested in ride comfort, the engine gets so loud at highway speeds (sometimes I'll wear earplugs!) Would like to improve this factor as well. May be solved by going back to stock airbox w/ the lower resonator box reinstalled.

Man, a 6 speed would be crazy... I'd love to have one. I kinda tend to agree with everyone else on here though, that I'd rather just have all my gears lengthened. INCLUDING 1st. 1st has good acceleration, but it's too short. Has anybody else noticed that, on a GT that first gear is gone before you ever get a chance to get anywhere? Oh well. I'm eventually going to put a 3S-GE BEAMS in my car, after I get some money. I'm leaving everything alone until I get that. Can anybody tell me how the gearing on that is, if I'll be doing any better than my 5S?

[Daftboy]

I believe that the blacktop 4age 6 speed fits right up to the 7afe...only thing I heard though is that tranny is like glass

[delusionz]

i can only think of trying bigger wheels and a speedometer corrector...

but i'd say the 6 speed in those sort of cars are designed to bring the gears in between first and final gear closer together to aid street acceleration (drivability) of torqueless motors and wont bring your cruising revs down, instead it'll give u a 5th gear which feels like ur old 4th gear.

my flatmates bz-r levin revs anywhere between 1 and 2 thou RPM higher than my car does thru its 2nd, 3rd, 4th, 5th gears at street driving speeds but then it's 6th gear brings its revs down to match my 5th gear, eg 3k and a bit at 100 kph.

[presure2]

e135 FTMFBBQ win in the celica, with a swap.
100+MPH in 3rd gear, and and a highway cruising rpm of ~3000rpm is where its AT.
6 speed would be a waste of time and money.

As some of you may or may not know, I plan to mate the auto trans U660E to my 3S-GTE. Yes, it DOES bolt up with the current bell housing. Unfortuately it's Auto, but I hear that it can handle the torque and can shift fast.

After the final drive ratios are factored in, here are the gear ratios for the U660E vs S54,

U660E: 1st 12.16 2nd 7.00 3rd 5.23 4th 3.68 5th 2.63 6th 2.24
S54: 1st 13.72 2nd 8.18 3rd 5.52 4th 4.29 5th 3.42

Would be great to go on the freeway at around 2000RPM...

[playr158]

and how do you plan on controlling said tranny

[devilsden97]

^Aussie magic ofcourse....kinda like pix dust. but only sold in Australia

the ue6 etc auto tranny is out of what? (i see u showed 6 gear ratios on an auto)

edit: ^'07 camry....i want proof it mates. because im calling bologna on this whole "it mates" comment

wow

[azian_advanced]

i'm surprised C-ONE isn't bankrupt yet... lol

[GriffGirl]

Some day I will have the blacktop w/the 6 speed tranny swapped into my car. It's my long term plan... sigh...

Actually the idea of running larger tires would be the easiest way to do it. With the downside that you increase the overall height of the vehicle, and therefore the center of gravity.

and how do you plan on controlling said tranny

We carry the PCS standalone transmission controller, he could use that. They work really nice, plus they all kinds of cool features, like you can add in paddle shifters, have different shift maps that you can swap between, control the shift harshness based on various factors, etc.

Hi all,

Reco's post regarding the C-ONE is not what I had in mind. The C-ONE conversion for the E153 or E154F will only bring the gear ratios closer together, which is good for racing purposes to keep your RPM in the power-band between gears, but at top gear your RPM will be higher than before the upgrade.

I currently have an A140E mated to my 3S-GTE. It's not known for it's strength, so I've had to set my shiftpoints to occur below 5000RPM on full throttle.

Yes, i purchased a PCS controller to control my transmission. it cost me almost a grand, so it's a bit more than I like. In theory the controller could also control a U660E.

The U660E is from Japan, and has been put in the late model Toyota Aurion and Lexus ES350 here in Australia.

OK, i am "pretty sure" U660E bolts up to the 3S-GTE:

A 3.5 litre 2GR-FE mates to both the U660E in the Aurion and the U151F in the new Highlander (Kluger).
The U151F will mate to the 2GR-FE as well as the 3.3 Litre 3MZ-FE in the old Highlander.
The 3MZ-FE mates to both the U151F and also to the A541E in the Camry.
The A541E is interchangable with the E153.

It is therefore highly likely that the 3SGTE will mate to the U660E. My main concern is actually whether we can create/aquire adequate brackets and mounts to support the trans in the celica engine bay, and also whether the transmission will actually have room to fit inside.
