Need help! trying to ID si tranny.....

this guy is selling a tranny and he said it was an si. the numbers i got off it are:
L3-1629594 and PL3-A000

anybody know if its an SI or not? just want to make sure before i buy it. please help:bigthumb: :bigthumb:

http://www.d16a.com/d_series_trannys.htm says its a dx. but if you can get to it again before you buy it they also have a test on that page to find out if it is by spining the shaft a certain amount of turns and seeing where it end up. check it out.

thanks, dude...no doubt its a dx tranny
