Has any one used the Motul gear 300 in their trans w/ a LSD? I worked at a shop and had some left over from several jobs I did and decided to put it in my trans. It was 75-90 weight. I have tried the GM syncro mesh fuild before and didn't feel a thing. I would like to get the trans upgraded later on down the road. It is a LS trans w/ a LSD "not sure of the brand of the LSD" and a Type R final drive. The trans was like this when I bought the swap. Thanks
