Its not all manuals that have the problem. Its molly oil additives in trans with yellow metal (bronze etc). The Molybdenum Di Sulphite bonds too well to the yellow metal & when it rubs, it strips the metal off. The sincro is worn away quickly & so the problem you see. The old graphite additives of 70 years ago dont have these problems.
If you can get onto a Lubrication Engineer at one of the oil companies & they know of the issue they can usually recommend a product, normally not one of their high tech/high priced ones. Good luck!
