1949 Plymouth transmission fluid

[Los_Control]

While we are talking about transmission/differential oils ..... I claim I use super tech gl5 from walmart because it is cheap and available ... claims it works with soft metals.

 

What about foaming?

I'm a little concerned with the amount of foam. I drained this oil 1 hour ago .... just full of bubbles on top.

 

 

For some reason I feel this is not normal ... maybe I need to change my oil brand?

I put this oil in the rear end of my daily driver chebby about 6 months ago .... It seems fine, I ran a magnet through the oil searching for metal .... found none.

Is it normal to have all the foam?

That foam is odd!  Never seen that before, even draining when hot, fresh off there road.  Engine and hydraulic oils have anti-foam additives and I'm pretty sure so do auto trans fluids.  Never considered it in gear oil.

Seems I have no choice today, I have the exact same product to put back in it.

I just need to decide if I want to replace it or if it is a non issue.

3 hours later and it is exactly the same .... foam. It is not going away.

 

I actually need to clean the pan, install new oil ....  but just curious what others think about it.

Is this really just poopy poopy oil? Or it is just a non consequential issue?

 

Mark me at scratching my head. .... Makes me wonder how it really performs under load.

There should be a tech support number you can call somewhere on the container.  There's a possibility it's acquired some moisture somehow and could give the gl5 some strange characteristics.

I was watching a Gale Banks video about his rear diff cover and they showed it what happens.  But I imagine the bubbles should go away after sitting?

Thanks sniper that is a good video ..... I see foam is created ..... after 3 hours sitting in the drain pan it never went away  .... I needed the pan as using a brush and gasoline to clean off the offending front wheel bearing. .... So it is gone now .... but 3 hours later it still had the bubbles and looked exactly the same.

 

Just unsure what to think about it.

 

You can relax @Sniper I do not need a rear end transported .... I just need to replace a failed front wheel bearing ..... I swear I thought it was  bearing in the rear end.

So I ordered a complete set of bearings & seals for this rear end ..... over $300 worth and it turned out to be a $35 front wheel bearing.

 

Sucks to be stupid .... I did get a bearing splitter and a new clicker torque wrench out of the deal .... I have complete set of bearings/seals for the rear end on the shelf if ever needed. ..... I figure as long as I have them, will probably never need them .... good cheap insurance.

 

@sniper will be heading down your way sometime next week to pick up some ashes.

More conflicting info.  According to the photo of the lube info page of a 49 dodge found on the Old Cars Brochure web site, the three speed manual trans takes 2 3/4 pints of SAE 80 gear lube.  The Gyromatic  needs 3 pints of Sae 10w engine oil.  Fluid drive unit says after an initial fluid level check at 1000 miles, checks of fluid level and top off if required is every 10,000 miles.
