Help me out here...I just picked up a B-series trans with no markings externally, I opened it up and it's definitely a 4.4 f/d and has an LSD. I haven't removed all the gearsets (hoping I don't have to) but feeling underneath the ring gear it seems it has the tapered/conical face on the other side of the diff, not the bulky body of the torsen-type. What model of Honda came with it, and is it in fact a clutch type diff? Will I require special fluid or will Honda MTF work OK with it? OR...is it an aftermarket unit? It seemed like the tranny hadn't been opened before so I assumed it was all stock.

Thanks in advance.

 

Get it open and snap some pics of it.

 

Blah, didn't want to take the shafts out, but if you insist I suppose I'll have to...I have rarely seen the type of diff I think this is but on occasion I've seen them on Ebay mixed in among the hundreds of helical types on there.
