Lost my overdrive
My father-in-law put a 1947 international KB-6 cab on my 1992 dodge chassis with a cummins engine and automatic trans. in the proccess we lost the overdrive. changed all the instrament cluster for individule gauges including speedometer. Not sure where to start looking for the problem.

Yes but no room under the hood so we moved it under drivers side fender and weather proofed it
