The transmission in your Honda Accord plays a crucial role in the car’s performance. So, you must troubleshoot and resolve any transmission problems quickly before they worsen.
First, identify the issues affecting your Honda Accord transmission. You can do that by using onboard diagnostics to check for fault codes or by looking for symptoms. Those symptoms include loud noises and performance issues like delayed shifting, jerking, and slipping. In many cases, low or dirty transmission fluid is the root cause, but you might also have to replace defective solenoids and gears.
This guide will help you understand the ways you can identify Honda Accord transmission problems. Then, you’ll learn what symptoms to look out for and how to troubleshoot the issues you discover.
How Do You Identify Honda Accord Transmission Problems?
The first step to troubleshooting Honda Accord transmission problems is to know there’s a problem in the first place.
Unfortunately, the transmission system and its components are out of sight, concealed under the hood and across the vehicle’s body. As a result, you won’t be able to notice a transmission problem visually.
Thankfully, there are two other ways you can know when your Honda’s experiencing a transmission problem:
- Using onboard diagnostics: The first and most direct way to identify Honda Accord transmission problems is by using the onboard diagnostics system. These days, cars come with systems that recognize transmission issues and trigger fault codes, telling you precisely what they are. However, you’ll need a code scanner or reader to know what those fault codes are.
- By looking for symptoms: Not everyone owns a code scanner or reader, and that’s fine. Even if you did, you likely wouldn’t be checking it daily for any active transmission errors. That’s why most people identify those problems by paying attention to symptoms. Those include sounds, smells, and performance issues.
As a Honda Accord owner, you must understand what transmission symptoms to look for. That way, you can troubleshoot those problems quickly and prevent them from worsening.
The following section will help you identify and troubleshoot common Honda Accord transmission problems.
How To Troubleshoot Honda Accord Transmission Problems?
In this section, you’ll discover the four common symptoms of Honda Accord transmission problems. Then, you’ll learn why those symptoms occur and how to fix the underlying issue that’s going on with your transmission system.
1. Leaking Transmission Fluid
Symptoms: Your transmission system can only function correctly if it has enough clean transmission fluid. As you’ll discover below, many Honda Accord transmission problems are caused by a lack of transmission fluid.
As such, the first symptom of a transmission problem is leaking transmission fluid under your car on the ground where it’s parked overnight.
Leaking transmission fluid is reddish-brown in color. So, if you find that under your vehicle, that’s a sign that your transmission system has a leak and is at risk of suffering more significant problems.
Why it’s happening: Transmission fluid will leak due to cracks or breaks in the fluid lines. Besides that, seals that wear out naturally over time will also cause fluid to leak out, even when the car is parked.
Lastly, road debris can also damage the transmission fluid pan. For example, the impact of a rock can develop a hole in the pan through which the transmission leaks.
How to fix it: The solution to this problem depends on the source of the leak. Worn-out gaskets can be replaced relatively easily. However, replacing damaged fluid lines and pans will require more effort.
2. Loud Noises
Symptoms: The following symptoms in your Honda Accord are loud noises from the transmission system and its components. They typically include clunking, grinding, and even gurgling noises.
Remember: your transmission system should never make any noises that you can hear from inside your cabin. So when that’s the case, it’s a clear-cut sign that your Honda Accord is experiencing a transmission problem.
Why it’s happening: In most cases, loud noises from your Accord’s transmission are due to low or dirty transmission fluid. A lack of clean fluid means the moving parts aren’t being lubricated and are therefore grinding against each other.
However, gurgling noises are caused by air getting trapped inside the transmission system’s fluid lines.
How to fix it: You can fix this problem by draining your existing transmission fluid and bleeding the air from its lines. Then, pour fresh transmission fluid into the system.
Fresh fluid will lubricate moving parts and flow much better than old or dirty fluid.
3. Late Shifting
Symptoms: Another symptom of a problematic transmission is late shifting. Under normal conditions, the transmission will shift to the next gear at the correct time, preventing your engine’s RPMs from getting too high.
However, if the transmission doesn’t shift when it should, that means there’s a problem that requires your attention.
Why it’s happening: Unfortunately, low or dirty transmission fluid is also a cause behind late shifting. Still, it can occur for other reasons, like faulty transmission solenoids.
The solenoids are the transmission components that control fluid flow. Those solenoids will adjust themselves whenever the transmission system triggers them to.
However, solenoids won’t respond correctly when faulty, causing your car to experience late shifting.
How to fix it: As with many other Honda Accord transmission issues, always ensure that your fluids are clean and topped up. That alone will solve and prevent plenty of transmission issues.
Once you’ve confirmed that the solenoids are the root cause of the problem, you’ll have to replace them with new ones.
4. Slipping And Jerking
Symptoms: In the previous section, you saw how one of the symptoms is delayed shifting. However, it’s also problematic if the gears shift quickly but slip and jerk. Slipping is when the transmission doesn’t stay in the gear it shifted to and instead switches back to the previous one.
That issue is sometimes accompanied by the entire vehicle jerking as it struggles to shift and stay in gear.
Why it’s happening: The problem of your transmission slipping and jerking is another one that can be caused by dirty or low transmission fluid.
Unfortunately, the root cause can also be something more significant, like a defective solenoid or worn gears within the transmission.
For example, worn gears won’t catch on so easily, causing a jerky and unstable shifting condition. Worse yet, they’ll also struggle to maintain the new gear, causing it to slip back into the old one.
How to fix it: Suppose dirty fluids are the root cause of your problem. In that case, replacing it with fresh transmission fluid will fix the problem.
However, things are a bit more complex when it comes to worn-out or damaged components.
The transmission in your Honda Accord relies heavily on components like solenoids and gears. So when those parts are damaged or defective, you must replace them immediately.
As you can see from above, troubleshooting Honda Accord transmission problems can be challenging at first. That’s because you can’t physically see the transmission system or its parts.
However, a problematic transmission has several symptoms you can look out for. They include noises and performance issues like late shifting, slipping and jerking.
Many of those problems can be fixed by changing transmission fluid if it’s low or dirty. However, if damaged or defective, you might also have to replace components like gears and solenoids.
