    Has anyone used or recommend any additive to a T90 tranny with dana 18 t-case? I was wondering if something Lucas oil was a good thing. My tranny/t-case/OD have been rebuilt. There is a slight leak from somewhere up there, can't find it, but I can live with it. The Lucas oil site says it helps with ease of shifting and even helps stop some leaks on seals. Just curious... I have not used it yet, but if recommended or other product, I may use it.
    Thanks,
    Paul

    I recently put Lucas in my T90 (roughly 25% lucas) and it seems to have helped with shifting and actually made it a little quieter. I was skeptical but it seems to work as advertised. It is definitely some seriously sticky stuff too!!! I would think because of that, it might help with keeping everything lubed.

    I got some lucas oil to put in the tranny. It mentions 25%-50%. Can I just ad the whole bottle and be done with it? Or do I have to drain the tranny and T-case, then add some based on the tranny and Tcase volumes?

    Thanks,
    Paul
