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:

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

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.

will the e56 bolt on to our setups easier than the e153?

it might.... but good luck finding one!

in that other thread in the n/a forum, someone has e56 with SS setup, so it might not be possible, or atleast without a suspension swap

Oh well, nice to c this thread. I have -94 ST202(129kw 3SGE euroversion) with super strut setup. My tranny is E56(manual) and its with LSD ?. Right now some bearings inside box are going to dead and i need new ones. Any idea if S54 fits straight to my car ? If not i have to repair old one and it costs more than some used S54(repairing its like 1200$ and used tranny costs 600$). Seems that these are VERY rare in finland...

Since its an E-series trans, it'll have most of the same issues as the E153. I've seen a pic of one once, and it looked just like the E153 on the outside. I'd almost bet that its an E153 with a different gear set.

Quick google search - a version of the E56 was used in the 1988 AWD Camry and Rav4. Need to do some research on that.

The axels for the E56 trans may be the perfect solution for the E153 conversion though, since they are the correct length for the celica's and made for an E series trans. I'd check the differential pinion part numbers, but its kinda pointless since the axels are probably not available in the US.



If I'm right, and the E56 is like the E153, then you would also need to replace 3 of the engine mounts to fit the S54. The E153 may be a smoother swap then the S54 for you.

Superstruts and McPherson setups are interchangable. I've had both setups on my car without changing the axels.

Just for reference, here are my recent experiences:

First, I fit the ST205 trans & axels into my ST185 - perfect fit.

Next I put an MR2 tranny with LSD and the MR2/185 axel combo into the 96 Celica ST. The result was the short RH axel talked about in other threads, but the axels fit fine when extended. This means that the 185/205/202 axles are interchangable in regards to the hub (ST and GT - same hub).

Then I thought, maybe the superstut suspension would fix the short axel. Swapped the 205's suspension and sub-frame over. No difference (verified with calipers). This means that the superstrut and McPherson setups and interchangable.

So, this leads me to believe that we can swap between C series (Celica ST), S Series, and E series transmissions providing we use the right axels.

I've heard some of the 205 rally guys swap out the superstruts with the standard McPherson setups for reliablity. Superstruts are absolutely great on street/track, but aren't durable enough for rally courses.

I'm about 99% sure it would be the same speed @ the same RPM. If not the same then very close. I think Manny is running the same profile tires I am. So we can check with his car.

This saturday I'll take a pic of 5th gear @ 4,000 RPM.

Also,
3 sets of tires 15" Stockers, 17" Falkens, and my drag radials. All break loose on the passenger side first. I can assure you its not tire pressure. What it is I couldnt tell you, it has boggled me since the first time I noticed it.

wow that could be a great axle solution if those axles fit perfect... like in the hud carrier bearing and all... Now I just wonder where to get them? How hard would it be to get curren axles?

part # and a dealership could do it

oh ****... used S54 is 600$ and used E56 is 1100$ !!! gotta fix the old tranny Talked with some importer and he said that here is only few st202 with E56 in Finland. Its some special addon for this model i guess.
