5 Causes of a Car That Won’t Go in Reverse

The three most important gears of any vehicle are park, drive, and reverse. You simply cannot operate a motor vehicle without these gears being fully functional. But there will sometimes be problems with your vehicle which will cause one or more of these gears to malfunction.

The reverse gear, in particular, will most commonly malfunction if there is some problem with the transmission or one of its components.

In an automatic transmission vehicle, it is easy to take it for granted when we shift the gear to “reverse” and drive backwards. We usually do this to back out of a driveway or parking space. Some people even like to reverse into a parking space before they park.

If you cannot perform this function with your vehicle, then your vehicle will likely be stuck wherever it is parked. You will have no choice but to figure out what the problem is so that you can restore your reverse gear function.

The Top 5 Causes

Below are the top 5 causes of a car that won’t go in reverse.

Low Transmission Fluid

If you have a low amount of transmission fluid in your transmission, you could have problems reversing your vehicle. Low transmission fluid can cause all kinds of problems with the gears, such as gear slippage, shifting problems, and overheated gears.

It is possible that your reverse gear might have been affected by overheating if your transmission is running too low on fluid. Perhaps you have a leak somewhere.

Worn Out Valve Body

Every automatic transmission has a valve body. This is the main area which directs the flow of hydraulic fluid to the valves. This is what allows the driver to shift gears so smoothly and to operate the vehicle without any issues.

However, if the pressure regulator valve or any other valve of the body gets too worn out, this could cause an issue with the reverse gear.

Internal Pressure Leak

The main shaft of the transmission may have a loose nut which is resulting in an internal pressure leak. If there is a leak like this, the reverse gear function will not be able to work properly.

Bad Speed Sensor

The automatic transmission has its own speed sensors. They are responsible for calculating the transmission’s gear ratio. If any of the speed sensors were to go bad, particularly the input shaft speed sensor, then it might cause problems when trying to reverse your vehicle.

Pattern Select Switch

The pattern select switch is what the driver controls to choose the driving mode they want. If the pattern select switch is misadjusted in any way, then you might not have the power you need when putting the vehicle in reverse.
