"Money can't buy happiness -- but somehow it's more comforting to cry in a CORVETTE than in a Kia"
The transducer is the speed sensor. It is driven by the speedo cable and converts the rotation of the cable into an electrical value that is proportional to the speed. The transducer then regulates vacuum to the servo. I don't know what kind of problem you are having, but have replaced alot of transducers in my day. Make sure your vacuum lines are good to the transducer and the servo holds vacuum.
Hope this helps!Joel Adams
