I honestly have no clue. The guy I bought it from said it was from an old skool turbo mini van. I just did brakes on my sister's 01 Dodge neon and it looked almost identical. Is the somewhere on the casing where it might say the code? All of the mounts are custom and it was a tight squeeze getting it in there. I just about have it fully installed at the moment. It has to be pretty trick because it is a reverse manual valve body. Are stock neon transmissions 3 speed?
