I have a Y1 tranny on my obd0 sir motor.......The Y1 also came in optional lsd. How can i find out if mine is an lsd tranny or not? thanks

 

it should say LSD on the top of the transmission.... Either that or you will have to take out the axel to look into the housing to see if you see a bar across the diff.... just look on the casing next to the transmission code and then check out the transmission code... you should be able to tell....
