You must have a different transmission than I have (which is a Tremec RTS), mine does not have an electronic take off for the speedometer.

... Also, with the 42% overdrive the speedo reads 75mph when the car is doing 62mph (100kph in NZ)
My transmission is 27% overdrive (4th gear). And since the speedometer take off is the original Model A gear, aft of the transmission, it has no bearing on what gear it is in as to how it reads.
