So i finally got around to chaning my speedo gear. I got under the car to remove the speedo cable from the tranny, and a little tranny fluid came out. I didn't want to keep going because i don't have time right now and i don't feel like draining the fluid. Do i have to drain the fluid first before changing the gear?

Also, my speedometer bounce. Do you have to remove the whole cable first to fix it ?
 
A very small amount of fluid will come out, perhaps a teaspoon or tablespoon but not more than that. Regarding the bouncing needle, I'm afraid it could be 1 of 3 things, listed in probable order: speedo head, speedo cable, speedo gear.
