Car Won’t Move in Any Gear Automatic Transmission
If your car won’t move in any gear with an automatic transmission, there are a few possible causes. Here’s a look at what could be wrong and what you can do to fix it.
1. Low Transmission Fluid
One of the most common reasons for an automatic transmission not moving is low transmission fluid. The transmission fluid helps to lubricate and cool the transmission, and without enough fluid, the transmission can’t function properly.
To check the transmission fluid, locate the transmission dipstick and pull it out. Wipe the dipstick clean, then reinsert it and pull it out again. The fluid level should be between the “min” and “max” marks on the dipstick.
If the transmission fluid is low, add more fluid until the level reaches the “max” mark. Be sure to use the correct type of transmission fluid for your vehicle.
2. Dirty Transmission Fluid
Another possible cause of an automatic transmission not moving is dirty transmission fluid. The transmission fluid can become dirty over time due to wear and tear on the transmission.
To change the transmission fluid, locate the transmission pan and drain the fluid. Then, remove the pan and clean it. Replace the pan and gasket, then add new transmission fluid.
3. Faulty Transmission Solenoids
Transmission solenoids are responsible for controlling the flow of fluid in the transmission. If a solenoid fails, it can prevent the transmission from shifting into gear.
To test a transmission solenoid, use a multimeter to measure the resistance between the terminals. The resistance should be within the specifications listed in your vehicle’s service manual.
If a solenoid is faulty, it will need to be replaced.
4. Faulty Transmission Control Module
The transmission control module (TCM) is responsible for controlling the operation of the transmission. If the TCM fails, it can prevent the transmission from shifting into gear.
To test the TCM, use a scan tool to connect to the vehicle’s computer. The scan tool can be used to read the TCM codes and to test the TCM’s operation.
If the TCM is faulty, it will need to be replaced.
5. Mechanical Problems
In some cases, an automatic transmission that won’t move may be due to a mechanical problem. These problems can include:
* Broken gears
* Worn clutches
* Damaged torque converter
* Failed input or output shaft
Mechanical problems can be difficult to diagnose and repair. If you suspect that your transmission has a mechanical problem, it’s best to have it inspected by a qualified technician.
How to Prevent an Automatic Transmission from Not Moving
There are a few things you can do to help prevent your automatic transmission from not moving:
* Check the transmission fluid regularly and add fluid as needed.
* Change the transmission fluid and filter every 30,000 to 60,000 miles.
* Avoid driving in high gear at low speeds.
* Don’t tow heavy loads without using a transmission cooler.
* Have your transmission serviced by a qualified technician as recommended in your vehicle’s service manual.
By following these tips, you can help keep your automatic transmission running smoothly for many years to come.
