    I recently purchased a 2004 4Runner v6 sr5 sport 4x4 that is approaching 200k miles. It runs, drives and shifts perfect and has obviously been very well taken care of but I have no past service records. My question is should I go ahead and service the transmission? The fluid looks and smells normal.

    I would probably do a complete trans oil change just for piece of mind. I am getting ready to do my 04 at 220k. Don't have it power flushed! Just do a fluid exchange, including the torque converter. If the previous owners didn't change the fluid regularly, then a power flush could dislodge debris that could clog your valve body.

    Here is a link to a DIY writeup.Make sure that your transmission matches the one described in the writeup!! This is for a V6 (1GR-FE) with an A340F 4-Speed transmission (with the dipsitck, not the sealed version).

    I would do everything as there's no proof of what has been done. There's a link for the owners manual with the maintenance guide in general discussion.

    I still need to do my transmission and radiator flush then everything will be refreshed from when I bought it, plus I just hit 100k a couple weeks ago so I need to do my belts for peace of mind.
