I was all set to add Slick 50 to my transmission when I read a mention in a recent post of the importance of trans oil spec due to the synchro cone material.( thanks be to the forum!) So I put the Slick 50 idea on hold. I know how polarised opinion can be on additives, and I wouldn't use it in the engine, but I had really good results with slick 50 in my old 911's transmission. Any input?
