Anyone have a part number for the solid teflon rings used on the input shaft and forward drum for the 200-4R? It looks like the same solid teflon ring could be used for the input shaft and/or the forward drum. The rebuild kits I have use the scarf cut rings for the input shaft. I would like to use the solid teflon rings. I thought there was a thread here a while back regarding the use of solid teflon rings from the 4L80 in the 200-4R. Was that regarding the center support sealing rings only? There is a teflon sealing ring used for the pressure regulator valve in the 4L80, I wonder if that ring would work for this application? If anyone has been here before, please post. Thanks, Kurt
