Joe, I have had syncromesh in mine for about 4500 miles now and the trans is like an extention of my arm. I shifts quicker than I can operate the clutch and not a single grind on the dragon.

change mine- change mine -change mine!

Oh, I'm not grinding right now and wasn't on the dragon. It tends to only do that in really hot weather. I already have some Redline that I'll probably use, though. If I don't like it, GM Syncromesh is next on the list, probably the FM version.

I know some manufacturers of differentials do not recommend putting synthetic differential oil in the differential housing. The clutches do not work properly and will lead to premature failure.

But I am talking about Eaton/Auburn differentials, don't know who makes the S2000's.

StrangeDaze

The S2000 diff is a Torsen unit. There are no clutches, so no worries on that front.

CANTONRACER

No clutches, as in it is a cone style differential unit? Those are the weakest out there.

StrangeDaze

No clue, man. I don't know what a cone style diff is... I think this is the Torsen homepage if you are curious:

However, I haven't read many reports on here of the Torsen unit itself breaking. People tend to break other parts in the rear end.

Torsen is all worm gears and is very strong.

CANTONRACER

I was thinking of something else and Torsen popped up. They are good units.

But I think there are still clutch packs in it.

Here's a quote from their webpage:

"There are no clutches or preload to worry about, in fact, the TORSEN T-2's patented parallel gearing system is designed to perform for the life of the vehicle."

They also have a pretty interesting PDF with more technical information found here:
