Hy tom moore, your serial number 2WA0311095 breaks down as follows
Year 1940
1 1/2 ton
133" wheelbase
manufactured in Tarrytown N.Y.
All of that information was obtained on this site, by going to the tech tips section at the top of the page, clicking on identify your truck, and scrolling down to the VIN Buster, then enter you serial number or VIN. As to your transmission it is a four speed, with a reverse lockout lever, its designation escapes me at the moment, but it is the correct transmission for your truck. The engine would have, been a 216 Chevy 6, hope that helps.
