I was reading a post a while back about remmys car and I think it said he found out he had a factory lsd in histranny and he didnt even realize it. I was wondering if all 99-00 civic si's with the b16a2 motor came from the fatory with an lsd or not? Ive never really spun my tires so badthat I would be able to feel if I had it or not so Im not sure.Someone help clear this up for me. Thanks.

 

remove your axles and look through the hole in the transmission.....if you can see right through it with no obstruction you have an lsd transmission......some people think that because they leave 2 black marks on the ground during a burnout, they have an lsd........not true, many of my sohc transmission have laid down 2 wheel marks with an open diff.

 

Straight from factory.. no you don't. now if someone installed one before you got the car is anotehr question entirely. and the only full way of distinguishing is to do what john said
