Default Re: 1939 Ford Transmission #’s

Looks like a truck tranny, the number you see is the serial number on tranny which would be assigned to vehicle when installed. It should start with 18 if it was for a V8. This number will tell the year produced, check Mac Vanpelts site for this information.BB means large truck I believe.
