Transmission Help

Okay guys, could you tell me what these plastic gears are? the orange one, and blue one? My speedometer isn't working, and I've replaced the speed sensor, and cluster gauge... so, my next guess is one of these plastic gears.

Those are the speedometer drive gears. All 2G N/Ts use the same one so unless one of those is original to a '95 car, I don't see why they would be different colors. In any case, the part number for it is M04797316.

Okay, thanks a lot. I just found the picture, so I'm pretty sure it isn't from an Eclipse. I was just wondering. The axle hooks right into that gear so are they hard to change out on your own? I'm not sure if it will throw anything off in the transmission. Thanks again for the replay.

Pretty much what I'm asking is, if I take that final drive gear (I believe that's what the speedo drive gear sits on) does it have to be put back a certain way? I don't wanna screw up the final drive ratio and so on.
