ok i just picked up a tranny for free today and i was told that it was a 1st gen b16 tranny how can i tell? here are the numbers on the tranny YS1-1011208 and on the inside of the casing i found these numbers P21. If anybody could help me that would be great thanks...............

 

count the teeth on the gears, or put it in and see if at 80 you're going 3000 rpm or 4000.

if its a ys1 from a b16 it should go 4500@80
if its a ys1 from ls it should go 3500@80

 

isnt that the b17 tranny? off of the 91 gsr.

92-93 gsr only no 91
b17 tranny=ys1 short gear
jdm xsi b16 tranny=ys1 short gear+lsd option

 

Hmm.. My tranny was replaced in my 91' RS B4 I bought it. It still has the junkyard #'s on it and all. I am wondering if they put a YS1 gsr tranny on it instead of the LS tranny. Reason for wondering is becuase i just went 15.4 in the 1/4 all stock except no muffler. Did it at completely full weight too. It also seems like the gears go pretty quick. When I am on the highway cruising at about 80mph my rpm's are about 4K. Could this be a gsr tranny? since the B16 is about 4500 @ 80 and the LS is 3500 @ 80.
