Unless there is a heavy synthetic, I wouldn't recommend changing to something else. Part of the deal is the clearances of the components and materials they are made of have the requirement of the heavier oil to make them function, too thin promotes excessive wear and heat, which transmissions do not like. The new transmissions have clearances between components in the .0005 to .0025 range, your A833 has clearnaces measuered in the .0015 to .006, meaning heavier oil is needed to keep parts from clacking each other and breaking, so not worth it to chance a thinner oil. Sorry to hear about the leaking side case.
