well driving home on the mass pike i just cruising at 70mph in 5th gear at 3.5k rpm. when all of a sudden my RPM raises without me even touching the gas and now i down shift like wtf. and yeah every gear my car doesnt move. the clutch doesnt sound like it engageing at all. woo to pulling the motor again to find the problem.
first ill check thing like the slave cylinder ect. but im so confused cause i dont hear any moving parts when i shif an let the clutch out. i cant feel anyhting in the pedal at all. /rant ps this sucks.

im hoping my clutch setup is ok and that my flywheel bolt havent sheared off or worse.

well ... its a clutch issue for sure. nothing wrong with your trans.

did u changed the clutch when you swaped? what did u put in there? did you brake it in when u installed it?

id agree with you but no bad sounds come from the tranny area at all. its a spec clutch rated for 420ft/lbs torque. broken in properly over 500 miles. its weird i dont hear any grinding or metal ratteling. confused. cause i mean if a clut breaks i assume you feel and hear it when it does. this is quiet as ever.

im not exactly an expert like some of these guys but what about your shifter cables?

edit if his axles fell out wouldnt he be dripping heavy duty transmission oil everywhere?

yes thats if it fell out. the cv could have gone too, and the axels would still be in there.


i had the same thing happend to me. thought it was the clutch too and it was the axel.

Wouldnt it be more likely that the axle would break under heavy strain, like at the track. I mean he was just driving a constant speed, seems a little hard for an axle just to break like that, and if it does then i am scared for my axles after this swap.

well today i put the car up on jack stands and started the car and both wheels spin but very slow and rpm doesn't influence speed. also with both tires off the ground not running if you spin one tire the other spins the oposite direction like it should but you can easily stop the rotation on the other wheel just by holding it. basicly its not an axel cause we checked them we think somthing in the clutch assembly did break. wether it be the disc of where the disc connects to the tranny splines. so i have to pull the tranny out again... so not happy about this. oh well the celica will be off the road for a while and im gunna turn it into more of a show(engine bay)/track car than a daily but come next year when everything is done i will be a show winner i hope. while the motor/tranny is out im gunna clock the turbo, get 3'in intercooler pipe, new FMIC and powder coat/ ceramic coat abunch of under the hood parts. also if i find a cheap 3sge tranny id buy it in a heartbeat.

why? you have a problem with your clutch, not your tranny.


im really surprised to hear that your axels are ok. did you get under the car and really inspect them well, or just go by the fact that the wheels were spining?

well my tranny i do have slight problems with. cruising speeds. tops speed. the syncros are going out. so eh. i inspected them pretty well. once i make some room in the garage ill pull them out. but we can hear a grinding noise coming from the clutch housing so thats what we really expect it to be. and its not the normal spec clutch grind/tick people normally hear.

no 3" intercooling pipe, i remeber reading a post on mr2oc that they gained like 12 hp.
its not much but i plan on going to a larger turbo in the future so i might aswell build up everything i can now so im 100% ready to make more power later. i plan on having the car off the road till next year so ill have plenty of time to play with everything.

guy, we've all said it to you here before.
you blowing up 3 trannys is more than likely some other issue, or your driving thats causing it.

i beat the hell outta my 175+k old, stock tranny with 230+whp and 270+ftlbs, with no issues, as well as several other members who daily drive theyre swaped cars with no issues.

i agree 110%

there is no way that with your mods (most stock with, with a topmount ic) that the tranny faild, 3 times in 2 years. there is some other problem going on with your setup or your driving style.

Why pull the engine to replace the clutch or tranny? JEhh... You can drop the tranny and figure out whats wrong, fix it, put it back together in a day.

yeah. 3in IC piping might be an upgrade on an mr2 with a HUGE turbo, but would be a horrible idea for a car with a fmic. the lag would make the car not fun to drive at all. i would do 2.25-2.50 max. you cant apply everything the mr2 guys do, to our cars.

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.

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?

A241E = 5S-FE, 3S-GE Automatic transmission

E153 = 3S-GTE Manual transmission
E50F = Alltrac Transmission

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

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).

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

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
