It came with one from the factory but I had trouble so it was decided to install a 700r4 in the early 90s. It has now come time to replace this unit and with the tech and parts available now I think the 2004r is the way to go.
I am on a very strict budget so I will be cutting some corners. I am retaining the 7 vane pump but will install hard rings and a stiffer slide spring. I am getting a carbon fiber band and raybestos red clutches in the direct but staying with stock borg warner in the rest of the trans. I just want to get it rolling again. I did get a .500 boost valve, larger rev boost valve and spring. I have been reading up on valve body mods but I think I will refrain from doing too much until I can make it roll. I do have a white accumulator spring to replace the broken one that came out.
Little lost here. But see you are rebuilding a 200 4r to. Did mine last year for my nova and also rebuildilng another one for the fun of it. What are you going to put this thing into? Part of my trouble is an old computor and not enought skills for it. You'll love that overdrive. I learned alot about these trannys. Good luck
