YES 3sgte with a 5s stock tranny., some thing is broken. woot. Options

[presure2]

With reading the MR2 boards, the S54 tranny thats on n/a MR2s is the same as the 3sge tranny. I think thats why it can take a beating because its over-rated for the 5sfe engine. Thats my hypothesis.

well, at the very minimum, i know for a FACT the axels are diffrent. ive seen jeffs compared to normal gt axles.

[Supersprynt]

Out of curiousity, did Jeff have to modify his axles at all? Or did they fit in perfectly?

[presure2]

he just rebuilt them.

is this a fact? i always thought that the s54 in all 5sfe were the same. but if the n/a mr2 tranny are the same as the 3sge tranny then this could be a better alternative than the s54 that came in the n/a celicas. our GT axles should fit in these trannies with no problem right?

The N/A MR2 and Celica have the same engine, hence same tranny. The 3sge seems to use the same transmission also, making me to believe the reason that alot of people are using S54's on 3sgte's and doing well with them is because they are in actuality, using a transmission originally designed for the 3sge, a more powerful engine which came before the 5sfe.

Now this my hypothesis, I'm basically thinking out-loud so critique is welcome. The difference in axles could be done for other reasons such as interchangability with other cars (Corolla/Prism,Camry?). Again, hypothesis.

This is a good read if any of you with 3s swaps or interested in knowing more about the 3s swap and general 3s/MR2 information:

the s54 offered with the 3sge, for mr2s and the s54 offered to us in have the same gear ratios, so thats another clue to whether or not they are the same.

i think supersprynt is right

[Defgeph]

My tranny came from a celica or curren, it's a FWD tranny. Not an MR2 tranny. My axles bolted right up(after a small rebuild).

[brianforster]

so then you have an s54 which is the same thing as a GT tranny?

[presure2]

heres a screenshot from my EPC.
the 3sge tranny is in fact coded as "S-54"
however, the trannys carry diffrent part #s, as well as the axels.
30300-2B570 3SGE tranny
30300-2B580 5SFE tranny
43410-20730 3SGE non-ABS axle
43410-20670 5SFE non-ABS axle

[brianforster]

dude, is that a program that gets you part numbers for toyota parts? if so, where do you get it :drool:

[presure2]

yea it is, it is the toyota distributed, electronic parts catolog. i downloaded it years ago, the link has since gone dead.

[lagos]

finally we get some soild info on what tranny that is.

[x_itchy_b_x]

wait so im confused. if i want longer gears and a higher top speed what tranny do i want?

[lagos]

wait so im confused. if i want longer gears and a higher top speed what tranny do i want?

the mr2 turbo one

[x_itchy_b_x]

wasnt there a 6speed tranny that people wanted to get there hands on? the solara tranny or somthing. maybe im wrong but. help me out.

[BBoYRuGGeD]

that tranny is dual synchros but not 6 speed i think...also i read that some of the mr2 turbo e153's also came with dual synchros but i dunno the year

edit: also from what ive read the camry v6/solara e153s have longer gearing than the mr2 turbo e153

also.... i know some guys with the solara tranny. they really didnt like the longer gearing . it makes the car a bit slower then the gearing in the s54.

[Defgeph]

so then you have an s54 which is the same thing as a GT tranny?

As we have just found out thanks to Manny.
I have a JDM S54, which has a few differences. From my personal experience, Axle seals are different, axles, input shaft, and whatever else might be going on inside. Also, the fact that when I launch the car the first tire to spin is the passenger side. For the USDM S54 its the drivers side(sitting in the car). Thats the one thing that I find odd.

My theory Tranny is designed with the driver on the oposite side of the car. So they make the opposite axle the initial drive axle. Then the short axles immediatley follows giving me the ability to leave two strips on the ground.But, I do not have L.S.D. Figure that one out


BTW: John, did you fix your tranny yet ?

[Aaagogo]

who rebuilt ur axle?

My tranny came from a celica or curren, it's a FWD tranny. Not an MR2 tranny. My axles bolted right up(after a small rebuild).
