I have a VDO speedometer with Hall-Effect Sensor, Tremec TKO Tranny. Trying to calibrate the speedo, I keep getting a message there is no data recieved. I removed the sensor and turned the shaft with a drill and got some figures on the speedo, but get nothing and unable to calibrate while driving the measured mile. Could something be missing in the transmission? Any ideas will be appreciated. I am ready for some serious driving now but not having a speedo makes me nervious when the eyes of the law are upon me.
