OK. as long as you are sure. Cause I thought I read the other day that Dexron IV is not good for our power steering systems. I just make sure the bottle says either Dexron III or Dexron III compatible. If it happens to be III and IV compatible, I use it. I forgot what I'm using. I'll look into this.
