hi, i am in the process of doing a transmission flush on my car it has 85k mi. and i wanted to know when is it recommended to do it at, mileage wise? and also how to do it because i want to do a complete flush and i know if i just drain it i will only get a portion of th fluid so how do i go about doing a complete flush, as far as getting all of the fluid in te converter and trans. cooler.

so if any one has a link to a site with instructions, that would really help me out.

by the way i have a 2005 sentra 1.8L

you need a flush machine to do a complete flush. since you probably dont have one, just drain and fill. or suck it up and take it to a shop.
