I own my second Dodge Neon. The first one I had was riddled with problems but I bought my current one anyhow (low miles, low price - should have been a sign)
2002 AT 55,000 miles
No reverse gear in Transmission.
Please help!!

 

Welcome to DF! Moving this to the 2ng gen Neon section.

 

Well the bad news is 2002 was the worst year for Neon transmissions. It was the first year for the 4 speed automatic and not very well thought out. Fortunately, Chrysler quickly improved them the following year. Mine took a crap at 81K miles and it was well maintained.
But, don't assume the worst. I would check the easy stuff first. Fluid level, fluid/filter condition, adjustment of the shifter cable and go from there.

 

Thanks for your response! So far my father and I have changed the fluid (ATF +4) and a filter and gasket change. We took a look at the linkage and cables, but not in depth. I took the car to Advanced Auto parts to have the codes checked, which I'm researching now. There were 8 total - all about the transmission. (Ratio mostly) I'm hoping to change the grounds in the car this weekend but I'm not really sure what I'm doing.

 

What were the codes?
