My speedometer stopped working in my 88 escort gt. I replaced the cluster, the speedometer cable and the speedsensor. Speedometer still didn’t work. I disconnected the speedometer cable from the transmission and connected my cordless drill to it and the speedometer hand moved. I’m thinking it’s the gear inside the transmission that’s not working. It’s a manual transmission. Does anyone know how to remove and replace the part on the transmission that the speedometer cable screws onto? Thanks.
