Well, many of us use Fords to tow Triumphs, so...

Do you have specific evidence to back up that statement? (Kidding, Greg!)

My 1991 Ford Explorer has basically the same speedo (internally, anyway).
And it's done this in the cold since the first winter I owned it; still
does it to this very day. I don't know what it is about the cold that does
it, but I can pretty much use my speedo as an ambient temperature gauge
(below, say, 15 degrees F, the speedo goes ballistic until the car warms
up thoroughly). As for rectifying the situation, I think there might have
been a Ford Service Bulletin on this; your dealer probably knows what to
do and can charge you accordingly to do it! :-)

true speed of about 40!)
