Default Auto lsd in a USDM 5 speed?

So I got a h22a JDM front clip. It came with an automatic (to my best knowledge) lsd transmission. I was wondering if there was any way I could use the lsd itself in my USDM 1993 vtec h22 transmission. Thanks in advance.

P.S. I did my best with the red button..

I think he may be right....I can almost remember seeing an h22 come back with an lsd auto once....

After looking over parts diagrams, I think it could work, it is worth a shot at least. Make sure you use the MT ring gear.

Good luck, and take pics of the attempt, I'd love to see

I'm simply basing that off the fact that the drawings for the AT diff and the MT diff are different, which implies each is accurate to its own trans. The ring gear had the same number of bolts (10) and the bearings looked to be close to the same on the inner race, which may indicate that the AT diff would be compatible.

None of this is absolutely trustworthy though..

You can't use an M2B4 lsd in a regular H22 trans, and they're both manual trans'. I highly doubt a automatic trans' lsd will fit in a manual trans case.

I looked through the website and could find any information on the auto lsd transmission. You said that you saw drawings of the at diff?

I'll try to be a little optimistic about it.

No lsd equipped transmissions were sold in the North American market. That's why those parts diagrams don't make sense. If you already have an lsd out of an automatic, go ahead and tear down your existing trans. I wouldn't even consider buying one though, just because it's not very likely to work.

What does you knowing what a lsd looks like have to do with anything.

Vig, we're trying to get a grip on whether the auto transmission's differential is compatible with the 5spd trans.

In JDM land they had lsd autos, which is what I believe he is referring to.

Matt, if the M2B4 diff won't work properly in a say M2F4's case, how can we reasonably expect an auto's diff to work?
