Planning on doing a simple transmission drain and fill. Looking into what I'll need to do it, like a new filter, , annddd a gasket for the transmission oil pan. Yet, I cannot find the part number, and looking around on here, I only found one https://www.clublexus.com/forums/ls-3rd-gen-2001-2006/839403-transmission-pan-gasket-part-number.html which was quickly cut off by the OP himself quoting something about Lexus using RTV or FIPG silicone for the gasket? Similar to this https://www.clublexus.com/forums/ls-3rd-gen-2001-2006/568795-naples-lexus-sealed-my-trans-pan-with-silicone-instead-of-using-a-gasket.html quoting issue with the paste asking if its standard operation??

So curious to know if there is a gasket or a make-a-gasket RTV/FIPG silicone paste.
Thanks!
