s54, rebuild/lsd options Options

[brianforster]

hey guys, at my local junkyard i can pick up an s54 with 140k on it for 75 bucks, i was thinking about doing it and possibly getting it rebuilt or adding a limited slip.

what do you guys think on this price? what does a manual transmission rebuild involve (changing the gears?) and do you think its worth it to take on a project like this?

there would be no time crunch and id have plenty of time to learn since i have a working tranny on my car right now.

do you think this could be a cheaper option than a e153 from an mr2 + axles + limited slip if i dont find one in it?

im not looking for much, i probably wouldnt even buy stronger gears, just maybe add a differential and rebuild it so it would shift like new. most of you know the car is still for sale but ive been considering keeping it now that i have a job and since it is only a few days a week and walkable from my apartment i might be able to do some extreme overhaulin this summer. this is just one of the ideas i am throwing around.

the tranny has been sittin out in the elements for who knows how long, but it wasnt rusted, had a working clutch in it and all the gears clicked, we know this cause we clicked around with the forks and pressed on the slave cylinder and fluid shot out! haha.

thanks for the input

Do it man. I'd love to see your results. 75 is a good price.

From my own personal experience. I wont touch a transmission with a 10 foot pole. The only way to fix something is to replace the worn out parts. To open it up, requires a bunch of special tools from toyota. To assemble it back together requires great attention to detail. There are a ton of parts in the transmission that needs to be installed in the correct order it. Nightmare!

i would buy it to just take it apart and learn more about transmissions. but i doubt you'll get anything useful out of it. aftermarket lsd's normally go for 900 or so, and i dont even think anyone makes one for the s54.

im actually in the process of doing this

how i ended up with two transmission.

Seems to me that LSD will only work in a C series transmission?

what makes u say that

this guy at the mr2 boards says different

"The S series and C series transmissions share differentials:

The S51 (Camry, Solara), S53 (90-93 Celica), S54 (MR2, 93+ Celica), C56 (MR2 Spyder, Celica GT), and C59 (Corolla, Matrix, excl. XRS) all use the same differential. The MR2 Spyder's helical LSD WILL work in any of these transmissions. The differential part number is shared between these transmissions. Same part number = same part. The MR2 Spyder, however, was the only car to receive a factory LSD that is compatible with these transmissions. It should be exactly the same as the TRD Helical LSD that was discontinued for the S54.

This is great news, because now we have the option of choosing a less aggressive LSD for our transmissions."

"Some OEM Toyota part numbers for you guys:

LSD differential, S54 (SW20, ST202):
41301-20190
- Substitute: 41301-20230

LSD differential, C56 (ZZW30):
41301-20230

It is a helical limited slip differential."

tell me what you guys think

i called toyota and the part number for the s54 the 20190 cant be pulled up in their system.

because it has been superceeded by the # under it.

If your running a 3sgte Id say get the e-153 and dont take any chances. I've seen the internals of both trans. and there is a HUGE difference. Also the axles are much more sturdy. This is coming from a guy that was left on the side of the highway Because my s-54 took a crap after a 10 psi boost run. Just my opinion

opps double post cus i hit the back button

oh and another thing to think about... not sure how ture this is as ive only heard it been said before and havnt seen actual proof but the e153 trans may be 70lbs heavier. coupled with the fact that i think the 3s is a bit heavier already it might make for a very nose heavy car. which really sucks around corners.

do you guys think that the ring and pinion gear from the S54 are interchangeable with the C60 and C65M transmission. The transmission that came with the 2000+ Celica's and MR2 Sypders.

Some how I think my S54 Transmission has the pinion and gear as the MR2 that came with helical lsd. Since I do have a MRS Helical Diff which are interchangeable between s54 tran.

The weird thing is that Urbandork this transmission from a junkyard. he then bought an mrs diff and had the transmission shop install it into the S54. Do you think its possible that they put a MRS Sypder pinion and gear in it without urbandork even knowing it??

[njccmd2002]

ask the shop, who knows what they did. Best thing is to open it up and count the gears...

[BonzaiCelica]

it was done at that shop back in 2007 you think they will remember! Yes I know the only way to find out is to open up the transmission. Damn I should of done speed runs/recorded some videos with my original s54 that came with the engine and with my new transmission. Hmm time to hit the books and learn how to take apart my own transmission and put it back together.

ill be getting some videos soon of mine... what do you neeed.

[BonzaiCelica]

I dont really need anything. All I need to do is open up my Limited Slip Transmission and my Original S54 that came with the swap and count the teeth on the ring and pinion.

I'm almost certain by from what Rusty said and the video footage I recorded that I do in fact have a 4.529 final drive gear ratio. That's something that I don't like Although it might be better suited for track. I would prefer to have a 4.312 final drive found in the 6 speed Sequential Transmission found in 2003-2005 MRS with Helical LSD with the 4th and 5th Gears from the S51 Transmission in my S54 Transmission.

THe current final drive I have right now is from C60 6 speed Open Differential Celica GT-S Transmission made from 2000-2005
