420a Tranny problems

[BigRand]

Okay moderator's can throw this in with the drivetrain stuff if they want but I'm specifically reffering to 2gnt tranny's.

Okay so here is my problem.

I've got a stage 2 action clutch, and back in june my throwout bearing (which seems to be half metal half plastic) melted and or got stuck on the metal sleeve that it grasps onto on the transmission. So I replaced the transmission because I had a spare one from my second motor. Well haven't really been driving my car around since my motor was being built and I blew my head gasket, until about mid septemeber when I got the motor in. Anyways about a week later and after close to 900miles of breaking it in, the exact same thing happens. Well now I've decided to replace the clutch anyways even though I was told it was fine. But I really just wanted something better. So I'm getting a new tranny, a STAGE 3+ SPec clutch, and I was wondering if there is a way to increase the strength of the throwout bearings in our trannies. or a better one I can buy that won't have this same heat problem?

Or if anyone has a built tranny and would like to tell me what they did to build it up that would be great as well.

I've never heard of a TOB melting to the input shaft. Is this a TOB that came with the Spec clutch? If so, I would suspect that is the problem and go get one from your old pal, Satan. My original was still doing a stand-up job at 142k and I'm sitting at 175k right now with the second that has been through two tranny blow-outs. They are pretty damn stout. They are still composed of a certain amount of plastic, but it's a hardcore, delrin-like, high-stress plastic.

I've been curious about upgrading my tranny in the future myself, but all the experts I have spoken with about the subject have told me that there really is no need aside from maybe engineering a metal-raced output shaft roller bearing. The plastic one in the tranny is somewhat sketchy and makes some of us nervous. Especially those of us who have had them fail.

Actually its the throw out bearing that came with the ACTION cltuch, and then they put another one in, but I don't believe they didn't right, so I'm gonna do it myself when I find time (I'm in school now so its hard).

The throwout bearing should come with the clutch right? or do you use the one in the car came with?

Also for my tranny I just wanted to get some kind of LSD in there, but I haven't seen one made for our cars besides the phantom grip. The only problem I have with that is that the phantom grip isn't exactly limted. Its always on lock.

Anyways thank's for the help, and any more information you got would be helpful regarding throwout bearings.

Hey Rand... Quaife makes an LSD for our tranny! Take a look around the net to find a good price!

Yup. I don't trust those PhantomGrip deals for shit.

As for your TOB, I would go get one from Satan. I have no experience with "aftermarket" TOBs, nor have I ever heard of "Action Clutch." Sorry.
