Transmission is not shifting - 1993 Diesel 1 ton duelly
 

:? HELP!!!!! I have changed the filter, and oil and now the transmission won't shift, It was working before i change it. What could be the problem?
Also the diesal gage always reads empty even though i have diesel fuel in it. What could be the Problem.

Thanks MaryAlice

Oh noo, the dreaded ford fluid change, sometimes its best to leave them pan and filters alone, seen this many many times, unfotunatley your gonna end up yanking the tranny to get a rebuild, its a goner now.

As far as your other problem goes> it sounds like you fuel level sending unit is bad in the fuel tank. That requires pulling the tank and R'R ing the fuel level sending unit assembly.
Goodluck, Cp
