Automatic transmission are very complicated.Īlthough the manual transmission is going away, if you happen to have a Neon equipped with one, a bad clutch can cause it not to accelerate. If it can no longer shift, it could be caused by a solenoid/valve body has gone bad, clutch packs, debris, and much more. If something has gone wrong in the transmission, your Neon may not be able to accelerate any more. You also wouldn’t feel the slight jerk your Neon as you put it into gear. If this were the case, there would not be any movement whatsoever from the vehicle. If you’ve broken a drive/axle shaft, your Dodge Neon’s transmission has no way to turn the wheels anymore. If the torque converter has gone bad, it will no longer be able to do this job. The torque converter is responsible for taking the mechanical power of the engine and converting it into hydraulic power. This is the number one cause of not accelerating but the RPM’s Go up. You should check the transmission fluid immediately. The power goes to the torque converter, and that’s the end of the line. If your Neon is too low on transmission fluid, it’ll will no longer be able to transfer power to the rear wheels. Here are the most common cause of acceleration with the RPM’s going up: This is typically a transmission related issue.

Somehow, the power that your engine is creating is not making it to the rear wheels. If your Neon won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue.

They can provide valuable insight as to what the problem may be, and really help you narrow down the problem. There is a section for each scenario with likely causes for each.īefore looking into anything else, if your check engine light is on, get a code scanner and see what trouble codes are stored in the computer system. Diagnosing the issue can be narrowed down by whether the engine is still revving when you push the gas or not. There are a lot of different reasons that can cause this. If your Dodge Neon won’t accelerate, that is a serious cause for concern.
