Hello i have a 04 nissan titan i just bought used. I habe 134000 Ive drove around 500 miles so far . And everything seems well. I took the truck in for a deep.inspection to see what needs to be done. my mechanic whom i trust been taking my nissans to him for years and is trust worthery. In the the inspection he said the transmission fluid looks a little dirty and recommends a transmission service in wich he will drain the fluid change the gasket and filter and re fill. Now. Im very superstisious about tranmission fluid . Im afraid if this is done it may cause transmision issues im currently not haveing any issues though since im new to titan. I want to see what you the titan experts think should i do it or is it not recommended.
