I saw a post about this acouple of days before and asked a question but now I can't find the old post that someone did. I looked in Hybrid , ALL MOTOR < and now Tech , so I need to know. I have a ys-1 LSD Cable transon my B16. I know sometimes times with cable trans the gears grind and the LSD makes noise. Well someone said to use this stuff called GM Syncro Shift ( or mesh ). I asked if all you do is replace ALL the trans oil with this stuf or just add a Quart of this GM stuff with regular H Manual trans fuild. Thanks like I said I tried looking for the old post before putting this one up but it's either two far back sinc it was on last friday or I'm blind. Thanks

 

Yes Drain and replace with syncromesh fluid.
