The transmission is the most important part of your car, especially if you have a family. This is because it has the ability to make sure that you and your loved ones get to their destinations safely and efficiently. However, there are times when things can go wrong with this component. If you notice any of the following symptoms in your vehicle, then you should take it to an auto shop as soon as possible:

The car will rev up but not move.

The first step to diagnosing a transmission problem is checking the fluid. If you suspect that your car's transmission is not working properly, take it to a mechanic or do some research yourself. Inspect the fluid level and color, as well as its smell. The type of fluid should also be noted, as well as its age and condition. In addition to this inspection, determine if there are any leaks in the system.
Finally, check for pressure within each gear that you can access on your vehicle by using a scan tool or other diagnostic equipment (if available). This will indicate if there is an issue with shifting from one gear into another--for example: if you're having trouble going from second-to-third while accelerating quickly uphill--it could mean something has gone wrong internally inside one of these gear sets inside your transmission case itself."

Strange sounds coming from transmission.

There are a few telltale signs that indicate you should take your vehicle in to have the transmission inspected. These include:
• A strange sound coming from the transmission. If you hear grinding or crunching noises when shifting gears, it could mean that there's a problem with the gears inside of your transmission.
• Transmission fluid leaking is another sign that something is wrong with your vehicle's transmission. If you notice any drops of oil around where your car's oil pan meets its undercarriage, this could mean that there is an issue with its seal and gasket (which may need to be replaced).
• Low levels of fluid or dirty fluid in general can also indicate problems within your vehicle's transmission system as well as other areas of its engine room like steering pumps and power steering circuits.

Car won't shift into reverse.

• If your Chrysler Pacifica won't shift into reverse, it's likely due to low transmission fluid (or ATF). To check the fluid level, you'll need a dipstick or a tube connected to the transmission and filled with ATF. You can find these items at most auto parts stores, or borrow them from your local mechanic.
• If the dipstick comes up dry or nearly empty, fill up with new ATF. If there's plenty of fluid on the stick but not enough in the tank itself, then either:
• The car has an issue with its transmission that needs repair; or
• The reverse gear is giving out (this is rare). In either case, it may be time for a new transmission.
