Just wondering if anyone has endevoured to install a modern 6 speed box in a Celica yet?

Doesn't seem to be any info around, just curious.

nope looks like best gearing is from e153 can be used for fwd and from what ive read all the internals can go into the e154f
(st205 tranny) this thread goes in depth about best gearings

yeah its been done, a stock 7th gen gts lol

http://en.wikipedia.org/wiki/Toyota_C_tran...peed_transaxles

Still just for the 7afe and 4age guys.. nothing for the 3s and 5s guys then...

good to know about the e153 gearset going into the e154f, st205 gears are stupidly long, especially 3rd gear and 4th gear, i fall out of full boost rpm on upshifts unless i redline each gear lol

anyone have the gear ratios for the 1-5 on the E-153 and the E-154-f?

you know, all E series trannies use the same case, so its a matter of swapping the diff, and bolting the transfer case on to the e153.

if i go the awd route with my swap, thats what im going to do.

yes, but i'm needing the gear sizes so i can try to find 6 gears slightly smaller (or considering the 5th off the E-154f as a 6th to the E-153 1-5 gears in the E-154f case)... i'm going to try building it into a 3S-GTE powered 6-speed AWD monster.... >:D

you cant just add a gear...

>
Can't is a strong word, you can have a custom gear set made.

>

indeed... every transmission case has room for 6 gears and a reverse gear... i'd need a whole new gear set (not sure IF i can play mix-and-match with the E-153 gears in the E-154f casing), a new shift fork, and perhaps a new shifter-shaft... maybe a new reverse gear too... but from what i gather, it can be done... just need the sizes (not ratios) of the gears in the E-154f... anyone have the numbers/link to where i can find them?

not trying to put anyone down if anyone can and does do this awesome for them and community

A 6th gear has been done with the st205 tranny...although the specifics are lost on me...

I have a 6 spd from Toyota Auris i imported from UK which will bolt right to a 3sgte/2GR There is also is a 4wd version in 2010+ RAV 4 2.2L diesels (Europe)
Problem is gearing for high torque applications and not sure it is best for 3sgte. I bought to use with a 2GR and is same as ones used in Lotus Evora.

This gearbox is beefy but smaller than a E series transmission due to 3 rows of gears instead of 2. Though this will easily fit into Celica it is going into a Mr2..sorry guys .


Here is listing of most of Toyota Transmissions . Note any with F are 4wd versions

2gr+6sp+mr2??

Yes, please.

2gr + turbo + 6sd + awd + celica. get on it.

it'd finally be an up to date gt4 lol

I don't know how well a stock 2gr would handle a turbo. High compression and FI don't mix.

I'd be happy with that setup, sans turbo. Intake, headers, and exhaust would open that 280whp monster up... And still get good gas mileage.

i don't see the celica, 3S-GTE, or the E-154f or even E-153 on there at all....

EDIT: btw... anyone have any idea of any lotus transmissions that bolt on to an S type block, with a 6-speed set-up? i'm thinking if that's the case, the gears can be transplanted into the E-154f??

IDEA IDEA IDEA!!!!

what are the EXACT gear ratios of the following transmissions (all bolted to a 3S-GTE):

S-54
E-153
E-154f

idea 1: E-153 1-4 with 4 and 5 off the E-154f acting as a 5th and 6th for an E-154f 6-speed conversion?
idea 2: S-54 1-5 with 4th OR 5th from the E-153 as a 6th gear in the E-154f hoursing?
general idea: any way to play with the gear sets between these 3 transmissions (i currently own all 3), to make a 6-speed out of the E-154f case?? if anyone has the exact sizes, or at LEAST ratios of all 3 transmissions listed above (when bolted to a 3S engine), PLEASE, for the love of the celica community, message me or something...

if i can do a 6-speed conversion, i'll GLADLY post a write-up of everything on here...

it wont work, there isnt enough space in the case.

why you would want longer gearing than what the e153 can give you, in a celica is beyond me.

hell, 110mph in 3rd isnt enough? lmao
yes, with a 225/45/17 tire, with the e153/3sgte in a celica, you can get up to just about 110mph, in 3rd gear, 140+ in 4th..)

>

i'm not wanting longer gearing in the celica.. i'm aiming for 6 shorter gears. why settle for 140 in 4th with only one more gear to go when you can get 120 in 4th with two more gears on top?

and i'm told (makes sense, excluding my old saturn) that every 5 speed transmission out there has room for a 6th gear if the gears are the right size...

>
I'm a bit confused by this statement. What you're saying is.... You want the same speed capabilities but with more shifting???

>
what your told, and what others have tried and done (read mr2oc) is 2 diffrent things..lol

why the need for more gears, other than to make the cool F&F noise during shifts?

here's something that confuses me... tell me if these figures are right, i pulled them from different sources, because the info is so hard to come by...

Gear Ratios
E-153:
1) 3.23:1
2) 1.91:1
3) 1.25:1
4)0.918:1
5) 0.731:1
Final Drive) 4.285:1
Reverse)3.545:1
Rear Diff) N/A

E-154f
1) 3.384:1
2) 1.913:1
3) 1.258:1
4)0.918:1
5) 0.731:1
Final Drive) 4.285:1
Reverse) 3.545:1
Rear Diff) 2.928:2

S-54
1) 3.285:1
2) 1.960:1
3) 1.322:1
4) 1.028:1
5) 0.820:1
Final Drive) 4.176:1
Reverse)3.153:1
Rear Diff) N/A

now, i realize the final drive on the E-153 is slightly longer than the S-54, but none the less.. if i'm reading these numbers (and assuming they're correct) right, the gear ratios of the S-54 are longer than the E-153...

now, what i propose.. shorter gears than the E-154f on all 5 gears, and add in a 6th as well... an idea i have in question, is what about using gears from a shorter geared 5 speed transmission, and an original gear, or just playing all-around mix-and-match... i get that there may not be space to mix-and-match to just add in one gear, but what about a custom gearset for this? if not custom-fab, piece it together from different cars' transmissions? just a thought...

>

because shorter gears means more easy acceleration... more gears means more shifting, but allows for closer gearing for better acceleration... less rotational resistance... why did anyone ever make a 6 speed in the first place?

Why did anyone ever make a 6 speed? To have more driving gears and therefore, higher gearing capabilities. I'm just slightly confused by what you're wanting. You want, and I'm making this up for the sake of having numbers, a top speed of 150. You can have that with the E153, or you are trying to make your own 6 speed that will also do 150, but with more shifting. You would lose time every single time you change gears, so I'm just confused by what you're looking for. Hypothetically, you might make it to 60 faster, but you also might not. Depends on how much time you lose when you shift.

As I understand it, there is X amount of room within the transmission case, and those 5 gears take up every bit of that room. No extra space for another gear. You CAN have 6 gears in that transmission case, but they will have to be custom gears. It sounds to me like you just need to decide what ratio you want each of your 6 gears to be and then have them custom made.

>

i probably will need to have them custom made... and what i'm attempting to gain is closer gear ratios to allow for faster acceleration, rather than a higher top speed (though that would be nice, i'm not too worried about top speed with the 3S-GTE)... as far as loosing speed on shifts, i'm planning on having a short shift kit, keeping the RPM's up, and the clutch i have should engage pretty quick... i'm not too worried about loosing time on shifting because of the build i have laid out... 9.4lb flywheel, 6 puck carbon-kevlar clutch, and a high-rev engine (all the bolt-ons will help get up there quick too with a light flywheel)... i should loose the same amount of time shifting with this build on a 6 speed as a 5 speed, just with an extra shift, yes... but that difference would be so minute that if i get the gearing JUST right with the 6 gears, that the downsized gears would more than make up for the loss of time on the one extra shift before my top gear (at which point shifting is the least of my worries with loosing time)...

balance i accept = shifting sooner < vehicle being more responsive and getting up to speed quicker

way i see it, shorter gears is like a lighter flywheel in the long run... reason i want a 6th gear instead of just a shorter 5 speed is to not weaken the power curve in the top end in higher gears, as well as maintain the same top speed and fuel economy, but get better acceleration at the same time. basically keep about the same higher gear ratios (6th gear would be a little longer than the original 5th)... the first 3 gears would be closer, and 4th would be a little shorter too... 5th would be slightly shorter, and 6th slightly longer. less rotational inertia to start/speed up, stay in the optimal power band still, and maintain nearly the same top end...

that's really what i'm going after here... besides, you can't really argue that a 6 speed gen6 awd race-tuned celica would be one sexy beast!! viper: 6 speed. corvette: 6 speed. lamborghini: 6 speed.

sorry if that got repedative, if my spelling is a bit off, etc... long LONG day today, and another long day ahead tomorrow... looking forward to more responses.

take it from a guy thats pulled the trannies apart, theyre right NO ROOM. what you'd have to do is, custom gears, custom input, output shat, custom selector assy (at this point you'd be better off with 7 gears IMO), and probaly a custom diff ring gear

>

why would i need a custom imput and output shaft? and why would you say 7 gears would be better? if i did replace all that... would it be possible to do it that way?

are there any other options for a 6 speed awd celica out there?

i say that cause the shafts are machined to accept the needle beatings, hubs, etc. (and each gear/hub is a different size) if youre adding all that, and another shifter fork, you will end up with one "blank" place, so why not?

only 6sp i know of is the actual wrc race gt4 boxes.

find a place that makes custom trannies, you will need them to get this done.

looks like they call these the TTE x-trac gearbox (aluminum, 6 spd) but will require more parts to get it working.
