My daughter bought a car two weeks ago. Before she drove off the lot, the "check engine" light came on. A salesperson came out, plugged in the computer,... reset the computer and told her the gas cap just needed adjusting. Wrong! The transmission is going out. I've taken it to a mechanic and AutoZone and both of their computers read the problem is multiple gear transmission failure. Duffy's will not do anything to correct the problem. The car is off the lot...it's not their problem anymore. There are many reviews similar to this. Do your homework and shop elsewhere...wish we would have!
