I'm running SF's SynchroGlide right now... It shouldn't be too hard to beat this report. Man oh man, I'm glad i did a UOA.

Copper and lead were mildly high in this initial sample of manual transmission fluid. Copper is not higher than average but it's out of balance in relation to iron. Are you having problems with this transmission? Manual tranny fluid rarely needs to be changed. Let us know if you are doing anything with your Jeep that would be causing the high wear. The insolubles were below average but we did find visible bronze metals in the oil. That may indicate poor wear at the clutch plating, which goes along with the copper and lead. We will keep an eye on it for you.
