Car Won’t Move in Any Gear: Automatic Transmission
Overview
When your car won’t move in any gear, it can be a frustrating and frightening experience. If your car has an automatic transmission, there are a few possible causes for this problem.
Causes
1. Transmission Fluid Problems
One of the most common causes of a car not moving in any gear is a problem with the transmission fluid. The transmission fluid is responsible for lubricating the gears and other moving parts of the transmission. If the fluid is low, dirty, or old, it can cause the transmission to slip or not engage properly.
2. Solenoid Problems
Solenoids are electrical components that control the flow of transmission fluid. If a solenoid fails, it can prevent the transmission from shifting into gear.
3. Shift Cable Problems
The shift cable is a mechanical linkage that connects the gear selector to the transmission. If the shift cable is damaged or out of adjustment, it can prevent the transmission from shifting into gear.
4. Torque Converter Problems
The torque converter is a fluid coupling that connects the engine to the transmission. If the torque converter fails, it can prevent the car from moving.
5. Computer Problems
The transmission control module (TCM) is a computer that controls the operation of the transmission. If the TCM fails, it can prevent the transmission from shifting into gear.
Symptoms
The symptoms of a car not moving in any gear can vary depending on the underlying cause. However, some common symptoms include:
* The car will not move when you put it in gear.
* The car may move slowly or jerkily.
* The transmission may slip or grind.
* The check engine light may be on.
Diagnosis
If your car won’t move in any gear, it is important to have it diagnosed by a qualified mechanic. The mechanic will perform a series of tests to determine the underlying cause of the problem.
The mechanic may start by checking the transmission fluid level and condition. They may also check the solenoids, shift cable, torque converter, and TCM.
Treatment
The treatment for a car not moving in any gear will depend on the underlying cause. In some cases, the problem can be fixed with a simple fluid change or adjustment. In other cases, more extensive repairs may be necessary.
If the problem is caused by a solenoid failure, the mechanic may need to replace the solenoid. If the problem is caused by a shift cable problem, the mechanic may need to adjust or replace the cable. If the problem is caused by a torque converter failure, the mechanic may need to replace the torque converter. If the problem is caused by a computer problem, the mechanic may need to replace the TCM.
Prevention
There are a few things you can do to help prevent your car from having problems with shifting into gear:
* Make sure to check the transmission fluid level and condition regularly.
* Have the transmission fluid changed according to the manufacturer’s recommended schedule.
* Avoid driving in harsh conditions, such as stop-and-go traffic or off-road.
If you do experience problems with your car not moving in any gear, it is important to have it diagnosed and repaired by a qualified mechanic as soon as possible.
Conclusion
A car not moving in any gear can be a frustrating and frightening experience. However, by understanding the possible causes and symptoms of this problem, you can be better prepared to deal with it if it happens to you.
