Okay so my speedometer went a little while back, I completely replaced it yesterday, but after installing it, realized that the old one wasn't even broken...
I took off the dash and hooked both the old and new one up to it and turned the other end, both made it move. I hook either into the transmission, put the car in gear and turn the tires (on blocks and once off) and it doesn't turn at the dash.
Needless to say I put the new one in, put everything back together, and I still have no speedometer.
I noticed when I installed the new one that there's a small assembly going into the transmission, which is where I presume the problem is.
Is this assembly easy to fix/replace, and if I do take it out, am I going to lose all my transmission fluid?
My car is a standard 1990 5.0 mustang GT.
Thank you for your time and assistance!

Alright so I pulled out the old assembly, brought it to Ford, got a new plastic gear with new teeth etc, tested it out by plugging in the speedo cable and turning it, the speedo in the car was was moving, everything looked good.
I stuck the assembly back in with the new teeth, and nothing, it wasn't turning.
I'm guessing now that it must be in the transmission, because I tested everything outside, and all was working.
On a side note, I stuck my finger in where the assembly goes to feel around, I felt the teeth on the inside from the transmission, they seemed fine, however I was able to turn them with my finger, not sure if that's normal.
Anywho I think I'm screwed because its inside the transmission? Do I have to pull that out to fix it.
Nice video, I'm almost tempted to try and pull the tranny and do it, although I don't have a shop or anything, just a driveway lol. Seemed easy, but I guess I would have to pull my exhaust as well to get it all out. My normal tranny shop charges 4 hours labour to pull/fix things in the tranny.
Maybe the pin that holds that gear came/broke off?
Originally when the speedo first went I was doing a couple of donuts, and after doing them I heard a ticking noise. That noise continued for about 2 days until finally something gave and the speedometer broke. I wonder if it was the clip rubbing against something till it broke?
Gonna have to see what my options are, I'm a recently graduated electrical apprentice thats pretty short on cash!
