So the 1996 SS-III with the 3rd Gen 3S-GE also has a Helical LSD being that it also had the S54-06D?

What was the E56 axel code?

And any information on the LSD equipped to the Toyota Levin/Trueno GT-Apex Silvertop 4A-GE 5 speed and BZ-R Blacktop 4A-GE 6 speed models?

Also do you have any information on the LSD equipped to the Toyota MR2 Turbo models with the 3S-GTE E153 gearbox?

the LSD on supercharged corolla / levin / trueno is interchangeable along all E series transmission,

the Levin supercharged comes iwth a E58 ( LSD ) transmission, this LSD can be installed in E56 ( same tranny non LSD ) and E153 found in MR2 turbo, Camry V6, Solara V6, ES300. << This is veriofied information and I have both trannies apart in case pictures are needed, internally these trannies are identical, except for the differences in years with some having dual synchros and better oil system. the Stock OEM LSD for these transmission was always viscous, in some countries there was a TRD dealer option, pre 1993 this option was hellical LSD, after 93 the options were hellical andclutch type ( usually used only on mr2s )

if the LSD is hellical you'll see a small ( ~ 5mm wide ) hole when looking insdie the transmission axle area, if the hole is rather large ( ~ 10mm ) is non LSD ) for clutch type, you'll be able to see the clutch discs. and OEM Viscous is easy to identyfy, you'll see the bar and a gear right before the bar, I'll try to get a picture of this.


I have heard that this is also true for s54 transmissions, the diff found on MR-S, Levin non supercharged and aftermakrget LSD made for either of these cars can be used on the s54 transmission but I have not personal experience with this fact.

E56-04C is the full code delusionz

i have heard this as well.
apparently there is a guy over on mr2oc that has used the mr-s lsd diff in the s54 tranny.

oOOOOHHHHH ok now I get it.

All SS-III celica's that came with 3rd gen or 4th gen 3S-GE engines came with torsen/helical LSD,

All SS-II that came with 4th gen 3S-GE Redtop is unconfirmed as to what kind of LSD it has, if any...

Okay so the Supercharged Corolla / Levin / Trueno engine is the 4A-GZE from the model GT-Z which we know also uses an E series transmission, being the stronger type to hold the torque from a forced induction motor.. I was asking about the NA versions which are also Superstrut/LSD equipped namely GT-Apex and BZ-R which use C series transmissions. Are these Viscous or Helical and are they compatible with the S series and E series Gearboxes? Also wouldn't hurt to know about the Supercharged's E58 trans while we're at it.

I agree we should get a sticky on these gear boxes, their gearbox codes, axel codes, what year and models they came from, what type of LSD they are and if they are compatible with our gearboxes, and if the gearboxes are compatible with our engines, etc.

the differential is not interchangeable between E series and S series transmissions, as for C series to S series it seems that they are pretty different, the part numbers of same year ( 1995 ) celica and levin are different which suggest the actual part is different.

the only diff that will fit in the S54 is the MR-S, LSD are mostly Viscous, with some OEM hellical in early productions ( pre 90s ) once hte viscous techonology was proven that became the standard on all LSD transmission with the option of hellical or clutch type through TRD.

I have a lot pf pictures where you can see the differences of HEllical, Viscous, and CLutch type when looking at the transmission, but I have no time right now to post them. maybe later I will get some time to post all that, their application and proven fitment list.

Ok that would be awesome, On a different thread we got some information from Edophus which suggests the 1994 and 1995 JDM Celica with 3S-GE/Superstrut (Rare models under the SS-II submodel with a differing chassis number) had an E56 with Viscous, and from 1996 onwards the JDM Celica with 3S-GE/Superstrut (SS-III only) has an S54 with Helical LSD -- One that is similar in mechanical design to the ST205 rear diff.

And the parts database at TRDparts seems to support this theory if you read it the same way he does -- being that there are two different TRD 1.5-way replacements for both FWD Celicas equipped with Viscous and Helical.

agree so if we can get all the transmission codes here in one place first, making sure they are correct. (maybe make a new topic and linking back to here for the discussion?) then I can finish the engine and transmission sticky thread. yay!

how does that look so far easy to understand? Definitely add those tranny's/LSD that we can swap over. do we want to add the auto's? keep adding guys

yes very clearly understood Rusty. yea you got that info right on the trd lsd's. hmm SS-II with tranny cod S54-06A to have viscious LSD???

How do I find out what my 1998 SSIII beams if fitted with? Will there be a code on the VIN plate in the engine bay?

will be on the firewall should be E-ST202- BLMZF then further down it'll show S54-06D (Helical) since its a SS-III Superstrut (BEAMS)

there was 1000 made Europe V-Edition MR-S made in from 2005-2007, and they came with helical lsd. now looking from this link on the nengun website for lsd made for the zzww30 and sw20 n/a version mrs they both have the same part number.

This is from my old 1995 SS-I:


This is from Rusty's 1996 SS-II:

So the Trans/Axel code for the SS-I was S54-04A

And apparently no Automatic Celica whatsoever, SS-III or not has any LSD, Could we confirm this?



Hey Rusty your trim is the same as mine on the GT4... Perhaps the trim relates to the 4 spoke steering wheel and the driver/passenger air bag, and the leather, etc.

cheers delusionz, I've added info above

hey wow it is interesting, maybe we can start a new thread in the interior unraveling the trim codes

Just want to confirm that the GT4 and GT4wrc have the same one?

Can we get the USA ST and GT owners adding what they have, would be a great help.

uhh USDM cars dont have a badge like japanese ST202 and ST205 have. Can you get a more clear shot of your chassis code and tranny badge, please Rusty its hurting my eyes

cant remember where i got this from but i'm pretty sure the D on the and of the axle code there means you have a helical diff, in toyota terms its a 4 pin diff, which is helical, would be worth finding the info about the axles codes then you can work out from the vin plate what you have, not sure what the B means on the st205 plate, i think it only has a helical diff in the rear, but open diff up front, although i know some came with an optional helical front diff. I think the data rusty has posted is spot on, but i am a little drunk hehe.

the thread happen to come up again and i saw it so, for reference, here is the S54 info from mr2oc

LSD differential, C56 (ZZW30):

It is a helical limited slip differential.
