Transmission Oil Cloudy

I just had the transmission rebuilt on my '28 roadster, and had 600W oil added. After driving for a few weeks, I checked the level. Upon removing the fill cap, the fluid ran out the fill hole and was cloudy/milky. Is this normal? If not, what does it indicate and what is the remedy? :confused:
 
Drain that dude & fill it with 140W, quality gear oil. WHY do we mess around with everybodys' WEIRD gear oil CONCOCTIONS? They're gettin' RICH off us, there are NO "MIRACLE" LUBRICANTS.---Just like making SOUP, if you put TOO MUCH CRAP in it, you SPOIL IT.

Bill, your right use 140w, I cant believe these guys are still going by an 85 year old spec book, as others said, water in trans, maybe thru the vent hole, or thru the top shifter plate
 
But oil is millions of years old, and was refined in the past year, so I'll stick with the thick stuff originally recommended. It helps to slow the gears for better shifting. I've seen some of the dealer mixed oil that is almost black, like dirty oil. I don't know what's in it, but haven't heard of any problems related to it, but I'll keep buying the Mobil 636 from the local bulk oil dealer.
 
I have a question could the new oils be foaming and creating a problem ?
I also would like to know if the new 600 W be foaming . Does the Mobile 636 have a anti foaming agent like some race cars use ?

It don't seem right about water or moisture mixing with 600W oil. 600W is what we use in the lubricators on steam engines and if it gets spilt or used for lubrication on an engine a steam cleaner want clean it off. It takes kerosene or gasoline to clean it off, water want cut it. It's designed to lub inside the cylinder with steam.
 
not getting involved in the what type of oil debate..
it sounds like you have water mixed with the trans oil which will cause it to get milky

ck the rear diff and see how that looks.... maybe the car was parked on a hill and it traveled into the trans

Seriously, in the old days, without electricity or battery chargers, folks would try to park backward, on a "hill", for a sure start. Mrs Bell rarely drove her '39 Plymouth, if it didn't start on her "hill", she'd coast out on the road, look PATHETIC, & wait for someone to come along & push her!

Good idea. Ask your mechanic if he used lubriplate or some other white assembly grease. Or drain it out and send it off to be anaylized. That will really tell you what's in it.

I like when someone just mentions some type of oil it throws some people into tantrum on this forum. If nobody wanted 600W any more, you wouldn't see it for sale at every antique car meet.
 
Sounds like foam to me too. Maybe try a different brand of oil from 140 to 250 weight. There isn't that much difference in the two.
