The 1999 Honda Accord is a good vehicle to own, but the automatic transmission is the most troublesome part. The problems with this car aren't the same for all models. Some people find the problem harder to diagnose than others, and there are a few signs that you should pay special attention to. If you notice any of these problems, it's time to get a new transmission. It's important to check your car's transmission every few months to ensure that the drivetrain is in working order.
