My clutch ONLY slips after a time of beating on it, ie, doing donuts, burn outs, hard launches, drifting, etc, etc. That leads me to believe that my cheap advanced auto brand gear oil just isnt holding up under heat since the clutch only slips after being beaten on for a while. The clutch is new, maybe 2000 miles on it. I was wondering what kind of gear oil I should use under these high heat circumstances to hopefully fix my problem.

you know, i got the same problem with mine, except its a little older (about 8K). I am replacing mine this coming weekend with REDLINE oil cause a friend from altered atmosphere recommended it to me. Serious its not a cheesy commercial or anything. Just make sure you get the weight right HaHa my friend really screwed up his shift speed that way.

Hey also, did you give the clutch the proper break in period? I was told to let it have 500 miles of regular driving, (no beating on it at all) before abusing it a little.

External transmition cooler will help alot. Plus I use syntetic oil, it performs under heat stress better than dino oil.

I swear, we need to start over. NEVER DOES ANYONE USE A transmission COOLER ON A MANUAL TRANSMISSION ENGINE!!!!!! For the love of God, that's only for automatic transmissions. IF you knew one thing that is a no brainer. Another thing, transmission oil has NOTHING to do with the function of your clutch. Think about it for about three seconds. Your clutch never sees ANY oil, trans or otherwise. Don't waste your money. It's likely the fact that it's just a cheap Advance Auto clutch. In fact, I'm pretty sure that's it. Please do some technical reading, you all are so far off it's not even funny anymore.

yeah the gear oil will protect your GEARS, and synchros...NOT your clutch...a clutch taht is beat on WILL fade because it is not meant to take that type of beating...if you're gonna do all that mess then you should look into kevlar/carbon clutches

Hey, the manual cluch has no oil in it. From the poste it sound like he has auto transmission. Sorry for missunderstanding.

No, he can't possibly have an auto. An automatic transmission has no clutch. It has a torque converter, which is ABSOLUTELY TOTALLY DIFFERENT. This thread needs to stop and everyone needs to go to http://www.howstuffworks.com and and read the chapters on transmissions, clutches, torque converters, and fluid dynamics.

i thought many (of not all) auto trannies had clutches that engage under hard acceleration and at high speeds to help gas milage

hmm, i thought auto trannies do have clutches... in terms of a 'clutch pack' which alternating discs of steel plates n clutch plates are bound together...

your manual clutch will see transmission oil if you put too much gear oil & blow out the input seal...same as the rear main seal... if that blows, your clutch would slip all the time & see some smokin' <saw that on a freind's car>

WAIT JUST A MINUTE...you mean to tell me that after all this time, i can't trust everything i read on here? this is bad. very bad.

and yeah, it sounds like your A/T clutch is low on oil. while you're at it, add some brake oil to your rotors to help the squeal.

At least for now I wouldn't trust anything said on this board. There are now hundreds of absolutely stupid newbies that have NO CLUE what they are talking about and feel free to give advice. Please keep your traps shut and leave it to us veterans who know exactly what we're talking about.

AUTOMATIC TRANSMISSIONS HAVE NO CLUTCHES EXPOSED TO FLUID!!!!!! They have many small clutch PACKS that are sealed, and are in virtually NO way similar to the clutch assembly in a manual transmission vehicle. If your clutch is slipping, it has NOTHING TO DO WITH ANY KIND OF OIL AT ALL, unless as above stated you uber-overfilled your transmission and blew out the seal. That is unlikely. Your clutch is bad, it's a cheap one, probably not broken in correctly. The phrase "A/T clutch" is something that is absolutely non-existent. In automatic transmissions the fluid is a hydraulic fluid used to change gearsets, lubricate, absorb heat, etc, it has nothing to do with any kind of clutch.

Rotate your axle manifold fluid, naturally.

ok here, I got corrected and understand my mistake. I'm sure many members here didn't know this. All my previous cars have been automatics. So natureally, I thought fluid could be part of my problem.

Well geez guyz... Im glad you hate us all so. I just wanted to recommend a good oil to the guy if he was gonna change it. I didnt pretend to know why our clutches do such a thing. Mine is prolly just used up (being unsprung and all).

okies... so altimaman & dima are experiencing "clutch fade"??? like in brake fade, the friction material is not up to par w/ all that abuse... & will "glaze" if they keep doin it or when the pressure plate springs get weak?

& the only remedy would be to drive like an old lady/ normal daily driving until they can afford an ACT or other higher performance clutch kit? (agh, i'd rather do brake pads than a clutch anyways)

But im the one with the other problem, and i own a ACT 6-puck. Should they really fade after 8K miles?

Exactly. Improporly broken in high performace clutches are toast. You should spend a MINIMUM of 500 miles in the break in period.
