Hey guys im rapidly approaching 15k miles on my si which was my transmission fluid interval flush on my old 8th gen. I was wondering if anyone has done this yet and if you have any tips or advice going into this. Also I couldn't find in the owners manual if it is a drain and fill or drain and flush that was recommended. I am probably going to go with Amsoil synchromesh as this has made all preious MTs butter. Thanks in advance for your input!
