I just happen to be sitting here w/my DSM for my '01 Fronty. Looking at the KA24DE specs (I'm guessing this is the same engine):

-as NUTZ said 75/90 gear oil for the tranny. GL-4 only (gonna have to check that on mine confused )

-For a standard differential: 80/90 GL-5

-For a Limited Slip Dif.: 80/90 GL-5 or you can use 90 if the temp. is above 0 degrees F. THIS MUST BE LSD OIL.

Hope this helps.
