Dodge neon, 1995, 122,000 miles manual transmission
i recently purchased a used neon sport and about 2 weeks ago started having problems with the speedometer. Prior to this I had to replace the clutch and transmission. After the transmission was replaced the problem with the speedometer started. What happens is while driving the speedometer will start to bounce and when it does that the car seems to feel like it will lose power. It kind of jerks. It mostly does it while on the freeway. It does it a little bit driving in the city but always on the freeway. Is there some sort of fuse or sensor that will cause the speedometer to do this and the car to jerk? If so how can I fix it? Also the speedometer will sometimes register zero and the mileage will not work either. Help!

The jerking is definately the transmission, make sure you have proper fluid levels. If you have manual tranny, let me know and I will tell you how to check it. The speedometer prob could be a few things. Your instrument cluster could be damaged. Speed sensor could be bad. If it has a speed cable from the tranny to the cluster, the the cable could be bad. Good luck

I have a 2000 neon with the same problem, I have found out that the gear in the transmission that meshes with the speed sensor gear was broken, I replaced the gear and the issue was resolved, a month later it broke again($10 gear) + labor which equals removing the transmission and disassembling it to remove the gear. The car was jerky and the speedometer would either not work at all or go to 120 and bounce around until replaced.
