I have a 2004 dodge neon that i just bought. I took it to a shop to look at it before I bought it, and they told me I needed to replace the motor mounts. I replaced the upper one so far, but it didn't really change anything. I don't want to spend hundreds of dollars on something to fix it if it won't be fixed. When I'm driving, the car is fine. But when at a stop light or stop sign it vibrates and shakes so badly. I was told it can mess my transmission up if the mounts aren't fixed, but I don't know if this is the actual problem? help, please..with any suggestions
