I have a tranny that i was told was an lsd, that I got in a deal. I dont know to tell. It cam with a dohc obd1 zc swap, but was no atached to it.

I was told that you can tell from the number stamped in the case by the fill plug. Any one have a idea?

Stamped by the plug it says: P20 B000. There is an X4 stamped on top of the tranny.

 

i dont think there is a d series trans that came stock with a LSD

 

there are no D series trannies that came with LSD.

 

Look where the axels go in if you see a bar there is no LSD.

 

or just slap the axles into the tranny and turn one. If they don't go the same way no LSD.

 

FYI: The JDM D15 Auto had a LSD stock also the ZC trans had the lsd also

 

not in manual IIRC.
