Shifting in and out of gear is probably an activity vehicle owners engage in whenever they drive.
Typically, changing gears helps your car take certain actions such as accelerating, stopping, reversing, etc. If, however, your gear seems not responding as it should, there is likely an issue.
But one gear many drivers don’t take too seriously is the reverse gear. Unfortunately, if this reverse gear fails to work, you won’t be able to back into a parking space and park.
And even if you can park, you may remain stuck in whatever parking lot you find yourself. In this article, we will talk about the causes of cars not going in reverse and how to fix them. Knowing the fixes can come to your rescue anywhere.
How Reverse Gear Works?
While automatic and manual transmissions do the same thing, in that they transform power from the engine to create torque in the drive wheels. They go into reverse in different ways and have a few different components that could potentially go wrong.
How an Automatic Transmission Goes Into Reverse
When you put a car with an automatic transmission into reverse the reverse gear solenoid allows fluidic pressure from the valve body to build up.
This activates the clutch pack and bands that control the reverse gear. At that point, power from the engine is diverted to the output shaft that powers the drive shaft to rotate in reverse.
How a Manual Transmission Goes Into Reverse
When you put a manual transmission into reverse, you take over control of the clutch. This starts with you pressing the clutch pedal to the floor and putting the selector into reverse.
As you slowly lift your leg off the clutch pedal you feel the reverse gear engage, and the car will want to move backward.
Reverse is a separate gear from all the other forward-moving drive gears and uses a three-year arrangement. An idle gear engages when you activate the clutch and move the gear lever into reverse.
The idle gear then slides into place to transfer force from the input gear to the output gear. This turns the transmission’s output shaft and drive shaft in the reverse direction.
What Causes My car won’t go In Reverse?
There are various reasons why your car won’t go in reverse. However, the cause will depend on your transmission type.
Cars with auto, manual, or CVT transmission have different issues that cause them not to go into reverse. So if you’re asking, why would the car not go in reverse? See why.
Reasons automatic transmission and CVT transmission car won’t go in reverse.
#1. Low transmission fluid.
Your car’s transmission relies on transmission fluid to keep it lubricated and cool. However, the fluid can only function well at the proper level. So if the fluid is low, the transmission becomes insufficiently lubricated and overheats, causing your inability to shift into reverse.
In fact, low transmission fluid will make transmission shifting difficult. However, while automatic transmission cars use the automatic transmission fluid, CVT transmission uses the tranny or CVT transmission fluid.
#2. Dirty transmission fluid.
Transmission fluid will usually get contaminated after some time due to its function–a reason it’s recommended you change if after certain miles.
However, dirty transmission fluid will not work as intended and cause many problems. One of which is prohibiting your car from shifting into reverse.
Another way to know if it’s a fluid problem is that, Sometimes, your car won’t reverse but will go forward. If you notice this, check your fluid level and condition. Ensure you use the right transmission fluid for automatic and CVT transmission.
#3. Damaged valve body.
The large maize-like component that helps circulate hydraulic fluid among other valves in an AT and CVT car is called the valve body. This valve body enables you to shift effortlessly from one gear to another.
If this component gets bad, these connecting valves won’t get the right fluid to function; therefore, staying unlubricated is not good.
Hence, gear delays in entering reverse and sometimes won’t even allow you to reverse no matter how much you step on the gas pedal. So if you’re wondering, why won’t my car go in reverse sometimes? It’s likely the valve body.
Sometimes, it could be the shift solenoid found inside the valve body. If this solenoid is bad, you will find it difficult to reverse. Depending on your car, you may be able to replace only the shifter solenoid. Otherwise, you will need to change the entire valve body.
#4. Faulty transmission selector sensor.
Many cars with automatic transmission come with a transmission selector switch. This selector switch has a sensor whose job is to tell your car’s computer (ECM) whether your transmission is shifting into drive or reverse.
The ECM, in turn, communicates this information to other sensors and components, helping you reverse. If, however, the transmission selector sensor is faulty, it won’t be able to pass this signal and, as such, will not allow you to reverse your car.
#5. Faulty transmission range sensor.
While some automatic and CVT transmission cars use a transmission selector sensor, some use the transmission range sensor. The transmission range sensor in many cars is mounted on the gearbox and, in some cars, inside the transmission.
Its duty is to help detect the gear you choose from the gear stick and whether it corresponds to the gear stick sensor. However, if this sensor is faulty, your transmission may not be aware that you want to reverse; hence, it won’t respond.
#6. Active park neutral switch.
Cars with automatic transmission have a safety feature called the park neutral switch. Its duty is to ensure your car does not enter drive or reverse, making it very useful when parking your car.
If, however, this switch is turned on, you won’t be able to reverse your car. So if your Toyota Camry will not go into reverse, try checking this park neutral switch.
Reasons your manual transmission car won’t go into reverse
#1. Faulty Gear Shifter Mechanism.
Manual cars have shift mechanisms that are different from an automatic. These shift linkages connect the transmission to the gear shifter. The shift linkage can become misadjusted or faulty in a manual car.
Thankfully, some of the shifter mechanisms are adjustable. We will discuss more about those procedures in a minute. It can also fail completely because it becomes worn or broken.
#2. Faulty Shifter Cables.
The shifter cable is another part that may require adjustment. When the shifter cable becomes stretched and needs to be replaced, you may hear a grinding sound.
You’ll also know that the cable is stretched because there will be a lot of play in the shifter. When the horizontal cable breaks, you can’t shift. However, if the vertical cable breaks, you will only be able to get into a couple of gears, normally the third and fourth.
#3. Bad Clutch.
It’s also possible that the clutch is the cause, but you would probably have other symptoms. For example, all shifting becomes difficult when the clutch fails.
You may also hear a grinding sound when shifting gears and the clutch starts to smell. A soft spongy clutch pedal should also be a warning sign that something’s wrong. Manual transmission clutches can last 100,000 miles or more if you are easy on them.
#4. Broken Teeth on Reverse Gear.
It’s possible for the Reverse gear to break. While it’s not as common as some other options, you don’t want to overlook the possibility.
Wear and tear is the most common cause of gear breakage. When this happens, the car will go in every other gear without problems but cannot be put into Reverse. In fact, the transmission should continue to operate normally other than with Reverse.
Car Not Going In Reverse – Symptoms
There are a few clues that can tell you if you’re dealing with a simple fix or something more serious. Pay attention to these specific warning signs to better communicate with your mechanic and avoid making the problem worse.
#1. Complete Silence vs Noises
If your transmission makes no sound at all when you shift into reverse, you likely have an electrical, linkage, or fluid pressure issue.
These are often less expensive to fix. However, grinding, clunking, or whining noises usually indicate mechanical problems that require more complex repairs.
#2. Intermittent vs Constant Problems.
A reverse gear that works sometimes but not others often points to electrical connections, valve body issues, or early-stage component wear. Constant failure typically means a component has completely broken and needs replacement rather than adjustment.
#3. Cold vs Hot Performance.
Problems that only appear when the transmission is cold might be fluid-related or indicate early valve body issues. Conversely, reverse that works when cold but fails when hot often suggests internal wear or overheating components.
#4. Associated Warning Lights.
A check engine light or transmission warning light alongside reverse problems usually indicates the computer has detected a fault.
This makes diagnosis much easier and often points to electrical or sensor issues rather than mechanical failure. No warning lights with reverse problems typically suggest mechanical linkage or hydraulic issues.
#5. Slipping vs Complete Failure.
If the car tries to move in reverse but slips or feels weak, you’re dealing with worn friction components like bands or clutches. Complete inability to engage reverse often indicates electrical, linkage, or severe hydraulic pressure problems.
How do you fix a car that won’t go in reverse?
Even if you aren’t a professional mechanic, you can still diagnose and repair your car the same way we do. Here are some steps to follow.
#1. Check The Transmission Fluid Level.
It’s easy to check the transmission fluid in most car models. However, we recommend using a repair manual for your particular car model. Here’s how to check the transmission fluid in most car models.
- Park the vehicle on a level surface and engage the parking brake.
- Start the car engine and let it run for a few minutes. Keep the shifter in Neutral or Park. (Some cars require the engine to be off for a check. Reference your owner’s manual to be sure).
- Pull out the fluid dipstick. It’s usually near where the transmission meets the rear of the engine. Be careful, the fluid may be hot.
- Wipe the dipstick off on a shop rage and put it back in the tube.
- Remove it again and observe the markings in relation to the fluid level.
- If the fluid doesn’t reach the Full Warm line, you need to add more.
If the fluid is low, you should also look for leaks. Check the system and repair any leaks you find.
#2. Read Codes from TCM.
Some code scanners will read DTCs from the Transmission Control Module (TCM). If you have one, plug it into the OBDII port and see if any codes can help that let you determine the problem.
While some codes are generic, others will pinpoint the exact issue. Use our trouble code library to decipher the information.
#3. Flush Transmission Fluid.
If you noticed that the transmission fluid looked old or burnt, a flush might help. However, not all manufacturers recommend flushing and some sealed transmissions are only to be serviced by the dealer. Look that information up in the owner’s manual before proceeding.
If you are going to change the fluid, make sure you have all of your supplies ahead of time. Don’t forget to take the fluid to a location that will dispose of it properly. Many auto parts stores offer this service for free.
#4. Verify Data From Transmission Range and Gear Level Sensor.
With your compatible code scanner, you may also be able to check the data on the various sensors. Compare the readings with what’s in the factory service manual to see if something is wrong.
It’s also possible that one of these sensors is simply contaminated. If that’s the case, you should be able to clean it off and reinstall it.
#5. Inspect Shifter Mechanism and Cables (Manual).
If you have a manual transmission car, you may need to adjust the shifter mechanism and cable. The steps to do this can be found in your service manual.
Additionally, you should check the clutch. If you can get your car into Reverse when the car is off but not on, chances are the clutch is the problem. Thankfully, it’s easier to replace a clutch than to repair a transmission.
#6. Contact A Professional.
You aren’t expected to know everything there is to know about transmissions. Some of the steps and data we provided can be overwhelming.
If you need more help completing any of these procedures or performing a repair, don’t hesitate to call a professional. By spending a little more money, you can have peace of mind that the job was done right.
Temporary Solutions
Experiencing a car that won’t go in reverse is frustrating. While waiting for a permanent repair, you might need temporary solutions. These quick fixes can help you avoid bigger issues. Here are some options to get you back on the road quickly.
#1. Manual Override.
Some cars have a manual override for the transmission. This feature allows you to manually shift the gears when the automatic system fails. Check your car’s manual to see if this is an option for you.
To use the manual override:
- Engage the handbrake.
- Locate the manual override slot near the gear shift.
- Insert a key or screwdriver into the slot.
- Shift the gear to reverse.
This can be a quick fix but is not a long-term solution.
#2. Towing Options.
If your car won’t reverse, you might need to tow it. Towing can prevent further damage to your car. Here are some towing options:
| Towing Method | Description |
|---|---|
| Flatbed Tow Truck | The car is lifted onto a flatbed and transported safely. |
| Wheel Lift Tow Truck | This method lifts the front or rear wheels off the ground. |
| Dolly Tow | Uses a small trailer to lift the front wheels off the ground. |
Choose the towing method based on your car’s condition and distance to the repair shop.
#3. Emergency Repairs.
Sometimes, you need an emergency repair to get moving. Here are some quick fixes:
- Check transmission fluid levels. Low fluid can prevent gear engagement.
- Inspect the gear shift linkage. It might need adjustment.
- Test the car battery. A weak battery can affect the transmission.
These steps might help temporarily. Be sure to get professional help for permanent repairs.
Tips to Prevent Your Car From Getting Stuck in Reverse
Avoiding a situation where your car won’t go in reverse begins with preventive measures. Here are the top tips to prevent your car from getting stuck in reverse.
#1. Regular Transmission Fluid Change.
The transmission fluid serves multiple purposes, including lubricating the moving parts, cooling the transmission, and transmitting power from the engine to the drivetrain. However, over time, the fluid can degrade or get contaminated.
Therefore, regular changing of transmission fluid is vital. Most manufacturers recommend changing the fluid every 30,000 to 60,000 miles, but this can vary based on the type of vehicle and how it’s used. Always refer to your vehicle’s manual for the exact maintenance schedule.
#2. Timely Repairs and Maintenance.
Ignoring minor problems can lead to bigger, more expensive issues. For instance, if you notice that your car is struggling to shift gears, it’s crucial to address this issue promptly.
This could be a sign of a bigger underlying problem, such as a failing transmission, which could eventually cause your vehicle to get stuck in reverse.
Regular maintenance checks can help identify potential problems early on. During these checks, a professional mechanic can inspect various components, including the transmission fluid, the clutch system in manual cars, and the solenoids in automatic cars. Regular maintenance can prevent minor issues from escalating into major problems.
#3. Proper Use of Clutch and Gear System.
In manual cars, proper use of the clutch and gear system is important. Here are a few tips:
- Don’t ride the clutch. This refers to the practice of keeping the clutch pedal partially depressed, which can lead to premature wear.
- Make sure to fully depress the clutch pedal before changing gears to avoid grinding the gears.
- Don’t use the clutch to hold the car on a hill. This can cause significant wear to the clutch. Instead, use the handbrake.
How much does it cost to fix a car that won’t go in reverse?
What would cause a car not to go in reverse is numerous, so how much you spend fixing it depends on the culprit. It could be from simple fluid and filter change costing around $20-$30 if you do it yourself or $100-$200 if you hire a mechanic.
If, however, you have to replace components like the clutch, valve body, solenoid shifter, reverse gear teeth, etc., you may need to spend high. For example, broken teeth on reverse gear cost around $1000-$3000.
If you start replacing such components, you will likely replace the entire transmission. This is why it’s important to maintain these components to avoid expensive transmission repairs.
FAQs.
Q: Why will my car go forward but not reverse?
While many things can result in cars not reversing, a low or dirty transmission is responsible for cars going forward but not reversing. Low or dirty transmission fluid will not allow proper lubrication of transmission components.
This will let you move your engine but can shift into reverse. Try filling or changing your transmission fluid.
If it doesn’t solve the issue, it’s likely the transmission sensor for automatic transmission. Whereas a bad reverse gear, shifter mechanism, lock-out ring, and clutch can be responsible for it in cars with manual transmission.
So if you’re asking, why is my car not going in reverse but going forward, now you know.
Q: Why won’t my car move when I put it in drive or reverse automatic?
If your car won’t move even when in drive or reverse in automatic cars, it could be due to two or more reasons. AT cars use a gear stick that tells your car’s computer which gear you’ve selected.
However, this gear stick has a sensor. If this sensor malfunctions and tells your car you are in neutral, your car won’t move even if the gear stick is in reverse.
Cars with AT also come with a neutral packing switch, a safety feature that prevents your car from driving or reversing. If this feature is activated, your car won’t move at all.
A faulty transmission selector sensor will also not let you move your car since it aid in reversing and driving your car.
Q: Is it better to replace a transmission or buy a new car?
Transmission replacement is no doubt very expensive. If the car is still new and holds its value, then it is a worthy investment to replace the transmission.
However, if the car is close to the end of its shelf life and has other underlying issues, selling your car and getting a new one will be the best option. Such cars will break down in no time, so spending such an amount on them will be a waste.
Q: Can you drive with a broken transmission?
Your car will move even if your transmission is broken; however, it’s not advisable to drive with a broken transmission. It will be just a matter of time before the transmission affects other vehicle parts leading to more expensive repairs.
Q: Will low transmission fluid cause no reverse?
Low transmission fluid will cause a no reverse situation for your car. The transmission fluid is important in keeping the transmission lubricated and preventing it from overheating.
However, if this fluid is low, it won’t be able to supply the transmission and keep it working properly. Hence, causing your car to not go in reverse.
Final Thought
Car not going in reverse indicates one or several components aren’t functioning well—we have highlighted the crucial ones in this article. The causes, however, depend on whether you own a manual, CVT, or automatic transmission.
For example, a car not going in reverse could stem from dirty transmission fluid for manual, CVT, and automatic engines. In contrast, a bad transmission selector will cause this in only automatic cars.
If you notice your car not going in reverse, try marrying some of the causes we listed above and what you’re experiencing.
Please note that most causes of cars not going into reverse are delicate and are best left to professionals to handle to prevent further damage.
