So, this weekend I will be taking my VX in for a transmission service. I found a writeup here on the site on how to drain and fill, but don't feel like doing it myself.. plus I live in an apartment and management doesn't like me wrenching in the parking lot. lol So, my question is, do you suggest a simple drain and fill? Or do I need to have the filter replaced as well? Can any tranny shop do it, or should I have it done at an Isuzu certified place? I assume, as with other vehicles this age, a flush is not advised.. correct me if I'm wrong. Thanks ahead of time!
