Does anyone know anything about Warford Auxiliary transmissions? I have one I am trying to find out if it has overdrive. The last Patent date on it is June 1 1926. This has a rear shift and not a top shift like I have seen online. Seems to be a 3 speed with overdrive, direct and under. Not sure how to check the overdrive ratio. Any ideas? I thought these for Fords but there is a data plate above the Warford logo that has "CHEV 1330" hand stamped into it.
