Sounds to much like right!! Tranny fluid is what I would go for! Sorry I did not make it back to answer your question but it sounds like you didn't need me any who.

I hope my obsessing on this isn't too annoying... I just hate to make "unrecoverable" mistakes, but I think I found an answer (may be not THE answer) last night I was playing "Mr. Science" since the Mystery fluid has no strong smell I decided to see how it would react... first I combined new brake fluid with new trans fluid in a cup.. it's like combining oil and vinegar... if stirred or shaken will emulsify, but remain separated otherwise (btw it does get kinda milky) in one container I combined the "Mystery fluid" with trans fluid, and in another container "Mystery Fluid" with brake fluid Here's a picture of the results http://www.frappr.com/?a=viewphoto&id=5591207&pid=10965003 as soon as the "Gunk" hit the trans fluid it started to spread, and combine with the new fluid, when stirred it remain emulsified when the "Gunk" hit the brake fluid is floated on top, and remained Separate, stirring got the 2 fluids to combine, but started separating within a few minutes Conclusion is... I can't be sure the "Mystery fluid" is transmission fluid (probably is though), but I know it is compatible with transmission fluid. So either the manual is wrong, or someone switched to trans fluid at some point in time... and given the condition of the fluid about 40 years a go ;) let me know if you see flaws in this logic... if not I'm gonna take the plunge an use tranny fluid, and stop boring you guys ;) THANKS TO EVERYONE THAT WEIGHED IN!
