Yah, today I drained the fluid from my tranny (about 280k on the 5speed). It was 75W90 AmsOil about from about 2 yrs ago. It definitely was not this color when I put it in. There seemed to be a slight accumulation of metal particulate on the drain plug and in the fluid, as you can see in the pics below. Just thought you might get a kick out of seeing it.
you sure are doing lots to that car. what happened, I think I remember reading something broke? if it did not brake what are you doing to it? I also remember seeing a wtb 6spd thread from you.
I can't say that I have not drained a manual tranny or diff that didn't have a bunch of metal fuzz on the drain plug. Big chunks would be a cause for concern.
Well the short of it is that my clutch imploded on itself. Or at least that is what I think happened. I will know for sure when I get the tranny out. I wouldnt know. I have never done a fluid change on a manual before. Looked pretty nasty to me. Granted there were no teeth or other large pieces but there was alot of shiny stuff in that fluid. It is only like a bit over 40k miles. That doesnt seem too long to me.
Looks like what I've seen on a few gearoil changes. As Dan said as long as there are no chunks it should be fine. That's why the magnet is there.
Same thing I saw in the STi when that was changed. Maybe not that much but similar. Mike said the same thing. That is normal.
yea, that's probably not good. but you can't really tell in the pictures. there's always stuff on the drain plug. that's why subaru puts a magnet in it.....it happens. actually, having heard the noises that poor thing was making, I'm surprised there wasn't big chunks of stuff in there. you should split the case open and see how things look (especially that #4 synchro :yumyum: )
The Amsoil holds up well. 40k miles isn't a problem for it at all, even under hard use. I swapped mine at 60k and did an analysis on it, and it was just fine. This was with a mix of daily, auto-x, and rally-x use. From what I've read, a bit of metal shavings is quite normal. The bigger problem is chunks as was already mentioned. You can have an oil analysis done too to see what parts have been wearing. This can help point towards normal wear or wear of the syncros, bearings, etc. that shouldn't really be happening. My analysis only showed a highish level of iron, basically enough in suspension to warrant a good time to change the oil. There was also a high level of silicon, sometimes from contaminants (dirt) or in the oil on purpose for anti-foaming which from what I read Amsoil does. The lab can't say what the source is, only that it exists in the oil. I didn't send in a virgin sample to compare to new. My analysis on post #10 http://forums.nasioc.com/forums/showthread.php?t=1489327
Yeah there were no big chunks in there. At least none that came out in the fluid and none that I could feel by putting my finger into the trans through the drain hole. I do not think that I lost any teeth or anything, although 4th gear has some real issues. I did find out what broke though. It was the clutch; however there was still some clutch left so my theory of wearing through the whole disc was not correct. You can see for yourself what happened in the pics. I have very little experience with clutches so I am not sure if this is a typical failure or not. The clutch was an OEM replacement made by exedy.
Holy ****! Lol, that is something. I want to say baddass, but it sucks on your end. Can't say that I've seen that before. It must have taken a lot to rip the disk apart, seriously. I really cannot imagine an organic disk having the holding power to rip that much sheetmetal in the hardest direction without some sort of defect. If you want a cheap hyper single let me know.
I would send those pictures in to Exedy. See if there isn't something they could do for you. That's just not right.
That is kind of what I was thinking. The clutch would slip at on a regular basis, so I had no idea that the sheet metal would pose an issue. I am assuming that this was an accumulation of wear/tear & metal fatigue caused over time. When it let go finally I was not being hard on it, just went from 2nd gear around 4k rpms to 3rd. Right when I put the clutch pedal in I heard a loud POP and had no clutch. I never thought about this. Although I dont know what I would get from it. Maybe they would offer me a direct replacement but that wouldn't do me any good since I am upgrading the clutch now.
Tell them it took out the trans input shaft and you already bought a new transmission--and upgraded while you were at it. :biggrin: Iono, either way good luck with the whole deal.
Wow.. It almost looks like it was installed backwards... though I don't know how one would be able to get the pressure plate on that way...
Wow, I've never seen that happen! Take pics and send to Exedy, they should send you a new clutch disc. That right there is something to be proud of! And whatever your 4th gear issues are, those metal flakes are probably the result. The oil shouldn't have that much metal after only 2 years of use, even if you race on it. ~Dan
Looks normal to me! 2 yrs isnt that long...Going 100K miles on one drain and fill with syncromesh is bad (yup! I did it!)
Yes, synchromesh = bad news. I didn't know you put that in. Synchromesh = 5w30. Subaru recommends 80-90. Oopsies.
Oh, I knew it all along. It took care of my grinding problems and thats all I wanted from it. It actually shifts worse now that its got regular old 75-90 in it. I'll probably be going back to "motor oil" soon enough :laugh:
i've actually seen that happen before in a buddy's nissan!! too much power when it actually tries to grab then BOOM!!!
