Wogden Posted November 9, 2012 Share Posted November 9, 2012 I am getting ready to put my '37 Junior tarnsmission back together and wondered what is the recommended weight and type of oil that is used today. Is anyone running a synthetic? Or just stay with the traditional type? Link to comment Share on other sites More sharing options...
Owen_Dyneto Posted November 12, 2012 Share Posted November 12, 2012 You can't go wrong using what Packard recommended at the time, simple gear oil (GL-1) in the appropriate viscosity. Without looking it up, they probably recommended SAE-90 in the winter and SAE-140 in the summer, it should be in the owner's manual, if you don't have one, why not buy a reprint? You'll find it a useful document. Link to comment Share on other sites More sharing options...
Dave Mitchell Posted November 13, 2012 Share Posted November 13, 2012 The synthetics work fine in the trans and rear axle, but simple gear oil will work fine too, you can put in a multi grade such as 90/140. Link to comment Share on other sites More sharing options...
Steamcar Posted November 19, 2012 Share Posted November 19, 2012 I use synthetics in both my 1941 120 and 1947 Clipper. The only issue I have is that if I shift gears too fast, the gears will grind. It is not a fault with the synthetics, but a factor of worn synchronizers in a 71 and a 65 year old transmission. I wouldn't change back to non-synthetic and am just a little slower in shifting to compensate. Link to comment Share on other sites More sharing options...
