I ,personally, would stay away from adding any more plates to the direct drum . The drum is fairly small and there is only so much real estate there. Thinner parts ( pressure plates ,clutches and friction plates) do not handle heat like thicker plates do. Use quality clutch plates and Kolene plated steels <a href="https://www.raybestospowertrain.com/performance-parts/kolene-steel-clutch-plates" target="_blank">https://www.raybestospowertrain.com/performance-parts/kolene-steel-clutch-plates</a> .Also , keep a close eye on the O/D servo piston pin bore. They wear and cause a pressure loss in that circuit. Sonnax makes a sleeve kit to repair it but the fixture to bore the case is very expensive. Try to find a local trans shop who is willing to bore it for you and install the sleeve. I spent 21 years rebuilding transmissions for a shop which had the contract with the state police . I have probably built 1000 AOD-E and 4R70-W transmissions. I would recommend replacing all of the bushings as well. Ron</blockquote>
