Hi - My sister bought a 2014 Honda CRV for super cheap because it has VTC rattle on start up I told her I could fix.  I don't live in the same city so couldn't help her look at it when she bought it. The VTC gear swap went fine. When I finally got to it, I drove it a bit and noticed a slight jetsons spacecar sound in second gear so looked at ATF.  It was really bad, dark and thick but not burnt. I drained and filled it. Still makes the slight noise and still shifts fine. If you have the radio on or if folks don't know or care about cars, they might not notice it. It has 165K on it. I saved the old AT fluid.  Should I put the old stuff back in, leave it like it is for a while, or do the honda triple drain/fill? What do you all think? These honda ATs are so different I'm not sure what to do. Thanks!
