speedo gear ??- Experts help!!
 
I need to know what speedometer gear (what number of teeth) is used with a TH400 and 3.08 gears. Someone told me that the internal drive gear is the same on all TH400's, but the speedo gear varies depending on application. Someone please help before I get a speeding ticket!!!
