    Dear allison man, I have a 93 coachmen class A diesel pusher with a cummins B5.9 and an allison at542. I changed the trans fluid and filters. Prior to changing the fluid and filters, the speedo was working. After changing the fluids and filters, the speedo quit working. I checked the wiring off of the trans and all the connections are tight. Any suggestions?
