Exclamation HELP tranny issues

On my way to classes this morning the spedomerter decided to crap out on me and it seems that this is related to how the transmission shifts. When the spedo would intermittantly work the tranny would shift fine. When the spedo would not work the tranny would not leave first. Does anyone know what is causing this and how to fix it? I am thinking it is a sensor somewhere that has become loose or has worn out.

It will not shift into second gear, it just goes to a neutral type situation. But it is fine in first.

When in "L" and you let off the diesel pedal the speedo would work until you hit the diesel pedal again.

The tranny fluid is at a correct volume.

The car is a 1980 300SD

If anyone could respond to this in the next few hours that would be great i am at school and don't really want to drive 10 mph home.

Thanks in advance

I don't have any manuals in front of me now but it sounds like the gear at the back of the transmission that drives the governor and speedo has sheared a key or pin and is slipping on the shaft. Your transmission probably has a rear pump too and it may all run off the same gear. I wish I had a manual here but I don't. I bet its all related, though. I will check when I get home. Eric.
