What's up guys, this is my first post here. I bought a 90 lx a few weeks ago. Car is in killer shape and stock other than flowmasters. It's an AOD trans so I've got a couple of questions. First things I had planned were gears and some transmission work. I only drive the car a few times a week but included is my 40 minute drive to work. I was 4.10's, I had them on a 02 gt years ago and loved them. What rpm will I be looking at with the auto? Also with the install it seems that you need some specialized tools? I want to do as much as I can myself but I'm not the most experienced person. Thanks for any info/advice!
