Transmission question

[Mugen405]

Ok, so I picked up a core B-series cable transmission from a local salvage yard with the intent to rebuild. I was told it came off of a 90-3 LS Integra. The only tranny codes I've ever seen on a B Series cable was S1, Y1, YS1, or J1. This one, however, is stickered as an "A1". Anyone have any idea what the hell I've got here?

I have never heard of an A1 trans, but it makes me want some steak.
I think I will go to the keg tonight, thanks.

that tranny should be a YS1. https://hondaswap.com/reference/index.php?mode=tranny

i just pulled a b18a swap out of a 91 ls 4dr teg and it had an A1 tranny. i think that tranny only came in USDM 4 dr tegs. they are really long geared, good for turbo, bad for n/a.
