Thats tranny, i meant axles.

lets not forget that the "s54" IS a part number, in a way.

i think all the s54s are the same, but get different part numbers because they might have different brackets on them for different shifter cables, clutch lines.etc...

this is an excellent topic!

I do not understand

the part #s listed are for transmissions found in celicas, not MR2s.

30300-2B570 > was in 94-99 JDM celicas
30300-2B580 > was in 94-99 USDM celicas

do you want the MR2 tranny part #s too ? I assure you, they are different

ok then can you post part numbers for the 5sfe s54 mr2 tranny and the 3sge s54 mr2 tranny

I wish I had some numbers on those axles.

We should first compair

USDM S54 & JDM S54 for celicas


Then once we have done that. Then compair

USDM S54 & JDM S54 for the MR2

It will keep the confusion down.

theres so much work involved in converting the 93 + E153 lsd tranny. Is the solara v6 e153 lsd ? I dont rememeber. It would be so much easier starting off with that being that its god all the shifter brackets + actuator set up for fwd not like a mr2 trans where the brackets are all setup differently. This tranny compared to my other one has much taller gears. Might make it a shy bit slower. My other 3 trannys wanted me to shift all the time. I feel like I can hold it in gear alot better with this tranny. It feels like I have better top end too. It just feels like this is the right trannsmission for out cars. Ill post some pics of the tranny tommorow.

we need to remember that Jeff's tranny is not from a Celica...it's from a Curren ( I think a 3rd gen 3sge Curren...)

You are correct Dustin. You should look to see if its the same part number for the curren

Are you sure about that or speculating?

I would assume that the Celica & Curren trannies would be identical, really no reason for a difference.

I wish I could...I do not have Curren part #s

I bet asianadvanced does though...

guys, i read this on the FAQ for the EPC from the place i downloaded it

=============================================
=============================================
WHAT ABOUT PART NUMBERS?
=============================================
=============================================

Now, there are different data CDs that go with the EPC depending upon which
country you live in Europe, Japan, etc. The version that I have is for Europe.
However, thanks to Toyota's part numbering system you can use PNC (not sure
what it stands for) which is the first 6 or 7 digits of the part number to
identify which part you need. The rest of the number is refered to as a
"locator number" and determines which country, color, trim package, year, etc.
that you have. All of the PNC numbers that I have checked so far, match up
with the microfiche that I have for my car (91T). If you are concerned about
whether a given part number matches, send me the number and I'll double check
it with my microfiche or local dealership.

this could explain why the numbers are different for the second half of the part numbers...

I would think that as well. The trannys would be the same for the JDM celica & curren.

Another theory is that I have L.S.D. I'm a little doubtful on that. But then again, I have never had any experience with an L.S.D. tranny.

One thing is for sure, I have a very strange tranny.

not sure how long this will last but heres where i got the EPC
http://www.yankeetoys.org/Docs.htm

i just googled for it, im sure the links will be taken down after 100 people from this site download it lol, but my DL is done so im not worried

http://www.mr2oc.com/showthread.php?t=174139

maybe that will help with your lsd tranny ID...but i doubt a 3sge tranny has it...

As far as I know there was no LSD for the S54 tranny. But with Dustin finding a part # for one, its kinda odd. Alot of ppl get confused when they look inside the diff and see a bar and then go on MR2oc and see "if you have a bar you have LSD. Well that only applies to E153's as ALL S54s have that bar.

I dont know, but my guess would be that you have an S54. I think any more details as to what car it came from and what year will be pretty hard to come by.

This was a fun game tho

wouldn't there be a number on jeff's tranny though, erik?

>
that EPC might only go up to 1995

what we need is pictures of Jeff's tranny, pictures of s54s with LSD & without LSD, and more infomation on 1995 Currens. Having the frame # of the Curren it came out of would give many answers, probably all of them.

i cant even get it to work

>

if you read a lot of posts on mr2oc about mr2 owners trying to figure out if they have lsd or not, youll notice a lot of people tell you that just because you have 2 burnout markts, dosnt mean you have lsd.

i know you said that when manny tires to do a burn out, he dosnt leave the same markings, but you have to remember that he still has a 5sfe motor. it makes different power and torque. his car also has a lot less weight then a 3sgte swaped celica. not to mention thats its two different drivers doing the burnout. so you really cant compare the two cars.

also, your car might have less/more torque steer because of the fact that you dont have power steering.

all signs point to it being a normal s54 tranny. the axels might be ticker, but that dosnt mean much because its the tranny you are comparing, and not the axels. they are still the same spline count and length.


the cool thing about all this, is that now we know why the s54 holds up well for us swapers. it was a tranny that was built to handle at least the power of a 3sge motor.


another thing to remember is that the s54 is really an updated version of the s53. if they did beef it up, or change anything about the 3sge trans, they would have renamed it to s55 like they did when they upgraded the 5th gen s53 to the s54.

Ive looked on my tranny for a part # and found nothing. I dont think they put the number on the bellhousing. Why would it be that easy

No S54 has LSD in the states so that'd makes it difficult.

Explain why my passenger side tire breaks loose first. I'll give you a prize.

You have to think just because they named the two trannys S54 doesnt mean they are exactly the same.

Think of for example the USDM 3sgte and the JDM 3sgte. Name all the differences on thsoe two engines.

We NEED exploded views of each of the trannys, so we can see whats different. Calling them the same is the easy way out.

We're deviating from my original hypothesis. The S54 transmission came on 3sge's and is the reason GT tranny's here in the states are holding up on the 3sgtes.

I dont know why ur passenger side breaks loose first, but if they changed the drive-axle this is the first I'd ever hear of it and would think its kinda pointless to do such a thing.

i dont think the insides of the 3sgtes are different, i thought it was the ecu and some other slight things

This is a weird coincidence. This was just posted in the Engine section:

The Tranny I sold Dustin (and is now owned by defgeph). Came from a 1996 Toyota Curren. RHD, 3rd gen 3SGE and non-lsd. I checked the part numbers from my copy of the 97 EPC, and the hubs, brakes, suspension and underbody were the same as the 6th gen Celica - therefore, just consider it a Celica.

When comparing the trans with the US version, the only real difrference I fould was with the final drive. Less Torque, more top end:

snip----
From http://www.megaboost.co.uk/mr2/frames/techinfopage.htm

USDM - 4.176 final gear ratio
JDM - 3.944 final gear ratio

Also check out the max speed per gear:

_______ US _________________________________ JDM____________
5th gear (Rev Limiter): 126mph_______ 5th gear (6500 RPM): 142mph
4th gear (6300 RPM): 100.5 __________ 4th gear (7000 RPM): 122mph
3rd gear (6300 RPM): 78.1 ___________ 3rd gear (7000 RPM): 98mph
2nd gear (6300 RPM): 52.7 ___________ 2nd gear (7000 RPM): 67mph
1st gear (6300 RPM): 31.4 ___________ 1st gear (7000 RPM): 40mph

----snip

IIRC, the LSD was in the E56 tranny, which was more similar to the E153 then the S54.

Perhaps the passenger side is breaking loose first for other reasons - alignment or tire tire pressure for instance.

Also, if anyone wants the ISO's for the JDM 97 EPC, I can put them up on my works sftp site later. You'll need the actual EPC program to run them, these are only the data disks.

an easy way to verify the gear ratio would be to have jeff take a pic of his MPH at 3-4k. then have somone else with a s54 do the same.


the max speed per gear, listed aboive, is compared at different RPM's...by the way.

Good stuff Scothaniel.

So it looks that the E56 is very simliar to the S54, but has LSD (among some other differences.
