Three years ago I gave up on trying everything under the sun to correct the bouncing Smiths mechanical speedo. I bought an electronic speedo from Nisonger for $345, a Smiths programmable electronic speedometer - part XES3/5-1Bxx-xx. I recall having to get an electronic plug-in part from Fortes, who I bought my TKO-600 from. The Tremec has an internal magnetic pickup for electronic speedos. Just followed the installation instructions, programmed the speedo for my tire diameter, axel ratio etc. It is dead on accurate and stable at any speed. There is a button and a toggle switch behind the speedo within easy reach that allows you to reset the trip odometer and to calibrate the speedo for you own car axle and tires. Best thing I ever did for gauges. Lamp is same wattage as original speedo.
