Trying to put transmission oil in 1950 dodge coronet


Recommended Posts

The fill plug for the 10W transmission  oil is accessed from below the car on the passenger side of the car.

You will see a metal tag on the trans that says use 10 W only..

The fill plug is right by the tag.

Thanks I got it done today car is running good. 

What kind of oil should I use for my rear end ???

 

EP 80-90 or EP 80-140 should handle just about anything you will encounter  

(PS: If anyone suggests K-Y lube, they're on the wrong forum)

I would probably try 80-90 first and if it whines, 80-140 might help.

Looks like it is a hydraulic oil. Not for gears.

This multi-functional, low viscosity fluid has been formulated specifically for tractors using a
centralized system to lubricate the transmission differential wet brakes, power steering and hydraulic
systems. Outstanding frictional properties provide chatter free operation of the wet brakes, prolonging
the life of the oil seals, hydraulic hoses and other rubber parts while also protecting gears, pumps and
other parts from high load wear. Recommended for equipment with common transmission, hydraulic,
final drive and wet brakes pumps where intermixing may occur due to implement attached.

You didn't really put this fluid in the rear axle?

That is fine for the transmission, you need a heavy gear oil for the rear axle. My Service Data Book (1953) recommends hypoid gear oil, 90 in summer, 80 in winter. Today we have multigrade oils that do the same thing.

You might have a devil of a time trying to undo the pipe plug that drains the differential!  On my 48 DeSoto, it is a female square plug that is the very odd size of 5/16's.  I had to special order a 5/16 male square end wrench, and it was no help.  Why?  Because someone in the distant past had tried to unscrew it and now the female square is rounded out!
