I drained and filled my tranny with synthetic gear lube this weekend after doing the transfer install. I put regular Hypoy-C in the xfer since Marlin recommends changing it after a few hundred miles, but will probably fill it with Redline before the Rubithon.
Anyway, you guys who have used the Redline gear lube, did it seem fairly thin? I'd say it seemed more like heavy motor oil thickness than gear lube. I used 75W90 MT90.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
