Speedometer problems...

I didn't think the 1995 model's had a problem with the speedometer..but.. here goes.

About a month ago, i noticed as i was accelerating..the speedo wasnt moving..stared it down and it suddenly jumped to where it was supposed to be..thought it was just a glitch, nothing serious, so i ignored it..well. Today, i noticed its getting worse, but slowly. several times today it wouldnt do anything, i tried hitting the dash, thinking it may be a loose connection, and nothing. It seems once it finally works, it works fine through the whole trip. BUT. I have always had speed sensor codes, which triggers the CEL...and it's actually stayed off for a while and has come back on..but to my understanding:

The speed sensor runs to the dash, to the ECU.Right?

I've done some searching and found the only Pathy's that seem to have the problem are the ones with the cable..so i know it's not that, as i have the round dash.. but..any ideas?

Thanks everyone! It seems if everything stays working nicely something has to be rebellious and create a problem...

I tried a lot of different things, but the only way I could fix my problem was to replace the cluster.

Probably gonna have to replace the cluster.

My speedo didn't work when I got the truck. IIRC, the speed sensor on the trans was somehow busted.

Hmm..id hate to have to replace the cluster..anyone think it might be the speed sensor since I get codes on it and it disables my cruise? Thanks!
