Mechanic I work with and has rebuilt many-many 900 trans thinks that perhaps the factory preload of the pinion bearings may be too great. This in effect begins wear from the get-go as there really isn't anything to wear in without wearing out. Another theory expressed related to the existence of bronze/brass particles from synchros in the oil passing into the bearings and being run between ball and race. From this I have tried to change trans lube frequently to keep it clean. Saab did not have much of a service recommendation for changing lube. It is obvious to me that the trans oil darkens - heat and use reduce the lube qualities - and then if you run it for 100k miles ? And factory lube is engine oil - designed for main and rod bearings, rings on cylinder walls ? Can this be right lube for gear face loads and ball and roller bearings? My simple thought sequence says that lube for two surfaces impacting each other as in gear mesh would be different than lube for two surfaces sliding against each other. SO thats my eleven cents worth.
