There are lots of problems that can go wrong with your transmission. One of them can be a problem with the reverse gear. There’s no need to panic just yet because this can be a simple problem with a simple solution, which can be fixed at home. Or on the other hand, a problem that may need a specialist. We are going to be looking at these reverse gear problems and it’s fixes.
Low Level of Automatic Transmission Fluid or Dirty Automatic Transmission Fluid
One of the causes of this problem is a low level of transmission fluid (ATF) or a dirty transmission fluid (ATF). Automatic transmissions use pressurized hydraulic ATF fluid to change gears, when there’s shortage of ATF or clogged dirty ATF this mechanism can’t work properly. The first thing to do is check the fluid level. Most cars have a transmission fluid gauge. Pull out the gauge and check the oil level, you will also need to check the texture of the transmission fluid.
Faulty Transmission Control Solenoid
Another culprit is a faulty Transmission Control Solenoid. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. This means replacing the Transmission Control Solenoid.
Faulty Transmission Speed Sensor
A failing Speed Sensor is another suspect that needs looking into. The Transmission Speed Sensor is a magnetic sensor that provides this information, allowing the transmission to shift smoothly. The sensor counts the internal number of revolutions of the transmission and transmits that information to the transmission control unit, where the data is used to determine the rotational speed. As the rotation increases, the control unit directs the changing of gears. When this is not working properly, this may cause the transmission to shift erratically or in some cases not at all.
