Car Shifts but Won’t Move: Automatic Transmission
If your car shifts but won’t move, it could be a sign of a problem with your automatic transmission. Here are some of the most common causes:
1. Low transmission fluid
Transmission fluid is essential for keeping your transmission working properly. If the fluid is low, it can cause the transmission to slip, which can prevent your car from moving. Check your transmission fluid level and add more fluid if necessary.
2. Dirty transmission fluid
Over time, transmission fluid can become dirty and contaminated with metal shavings and other debris. This can cause the fluid to lose its ability to lubricate the transmission, which can lead to slipping and other problems. Have your transmission fluid flushed and replaced every 30,000 to 60,000 miles.
3. Faulty transmission filter
The transmission filter helps to remove contaminants from the transmission fluid. If the filter is clogged, it can restrict the flow of fluid and cause the transmission to slip. Replace the transmission filter every 30,000 to 60,000 miles.
4. Worn transmission bands or clutches
The transmission bands and clutches are responsible for engaging and disengaging the gears. If these components are worn, they can slip and prevent your car from moving. Replacing the transmission bands or clutches is a major repair, but it may be necessary if your car has a lot of miles on it.
5. Faulty transmission control module (TCM)
The TCM is the computer that controls the transmission. If the TCM is faulty, it can send incorrect signals to the transmission, which can cause it to slip or fail to engage the gears. Replacing the TCM is a major repair, but it may be necessary if your car has a lot of miles on it.
6. Other problems
In some cases, a car that shifts but won’t move may be caused by a problem with the engine, the driveshaft, or the differential. If you have checked all of the above components and you are still having problems, you should take your car to a mechanic for diagnosis.
What to do if your car shifts but won’t move
If your car shifts but won’t move, it is important to take it to a mechanic as soon as possible. Driving a car with a faulty transmission can be dangerous, and it can also cause further damage to the transmission.
When you take your car to a mechanic, be sure to tell them exactly what is happening. This will help them to diagnose the problem and recommend the best course of action.
