Can you post a few photos?
It looks like there were no optional overdrive transmission available for trucks in 1955-1st series. However, a factory overdrive was available on Sedan Delivery and cars in 1955 (all year).
Do you know what year rear end you have? An overdrive with the original 1/2 ton 3.90 rear end would be a nice highway cruiser.
