91 F250 Transmission/Tach issue
Hey all, I have a 1991 7.3 idi. The tachometer is not working and the transmission is in safe mode. From what I have already researched the O/D Off Light should be on, however this is not the case. The light does work because it turns on when I turn the key forward, then turns off. I have replaced the Tach sensor but this did not solve the problem. Every so often the tach will work, however its sporadic then it quits working within seconds. Any help would be great thanks!!
