my f250 diesel won't shift gears

I have a 1990 f250 7.3 diesel not a powerstroke. The tachometer wasn't working, so I changed the tach sensor. Tach worked for about 2 minutes, then quit. So I put another one in and it didn't work at all. Where do I go to fix this problem? Any help would be greatly appreciated. Thanks.

We had a 90 f350 flatbed with the same problem about 10 years ago. Check with Ford dealer. I believe there was a TSB about that problem. Exactly what the solution was, I can't remember.
