Anyone having a viewpoint towards what oil to put into the trans of my 1929 Series 65? There is something about certain bearing materials being vulnerable to EP (estreme pressure 80-90 weight, the hypiod smelly one) transmission oils, but I believe that would be for slightly older cars. I have already put EP into the rear axle, but am slightly in doubt about the trans. An alternative would be 50-grade engine oil, whih I believe was specified for the transmission of my 1940 Chrysler. For the 29 the only words in the manual are "use Chrysler transmission oil".
