Your Honda CRV’s transmission solenoid plays a crucial role in controlling the flow of transmission fluid, providing the energy necessary to maintain your vehicle’s speed. The transmission solenoid is pivotal in enabling smooth gear changes. However, there are several reasons why this essential component can go bad. In this article, we’ll explore how to identify the signs and symptoms of a bad Honda CRV transmission solenoid and offer tips on addressing the issue.

Recognizing Indicators of a bad Honda CRV Transmission Solenoid
A malfunctioning transmission solenoid can manifest as various irregularities in the performance of your automatic transmission. These issues may include problems with shifting gears, decreased gas mileage, engine stalling, poor engine performance, or even complete engine shutdown. Additionally, you might observe the check engine light flashing, accompanied by the diagnostic trouble code P0700. Let’s delve into the specific symptoms associated with a faulty transmission solenoid in your Honda CRV.
Common Symptoms of a Faulty Honda CRV Transmission Solenoid
- Difficulty Shifting Gears: Vehicles equipped with automatic transmissions rely on hydraulic systems to facilitate gear shifts, with the transmission solenoid functioning like a clutch. When the solenoid malfunctions, one of the most common issues is difficulty shifting gears. You may experience challenges when shifting from 1st to 2nd gear, as well as between 2nd and 1st or 3rd and 4th gears. Shifting into reverse may become nearly impossible, and the gear could become stuck in neutral. Downshifting may also prove problematic, resulting in your car’s engine continuously revving. In summary, a faulty transmission solenoid is a primary cause of gear shifting failures. Additionally, the transmission might skip a gear, and one or more solenoids could become stuck in either an open or closed position. This situation impedes the flow of transmission fluid, making it difficult to shift into reverse.
- Delayed Gear Shifting: Automatic transmissions rely on electrical signals to maintain the proper regulation of transmission fluid, enabling smooth gear shifts. Insufficient electrical supply or contaminated transmission fluid can cause the solenoid to become stuck, leading to delays in gear engagement. This delay is evident when the gear refuses to engage promptly, often resulting in the gear getting stuck in neutral.
- Entering Limp Mode: When transmission issues arise, the check engine light may start flashing. In such situations, the computer’s sensor receives an unprogrammed signal, prompting the activation of a secondary program known as “limp mode.” In this mode, the vehicle remains stuck in 3rd gear after automatically shifting from 2nd gear. As a result, your car essentially “limps” rather than running smoothly. The engine enters a “failsafe” mode, which persists until the underlying problem is resolved.
- Engine Stalling or Dying: Difficulty starting the vehicle when the engine is cold can be attributed to various issues, and a malfunctioning transmission solenoid could be one of them.
Pro Tip: It’s worth noting that contaminated transmission fluid can also contribute to shifting restrictions. Therefore, it’s essential to ensure that your transmission fluid is clean. Sometimes, resolving this issue alone can alleviate the problem.
In conclusion, recognizing the symptoms of a faulty transmission solenoid in your Honda CRV is essential for timely diagnosis and repair. Addressing solenoid issues promptly can help ensure the continued smooth operation of your vehicle’s automatic transmission.
What to Do When You Detect a Faulty Honda CRV Transmission Solenoid
When you discover a malfunctioning transmission solenoid in your Honda CRV, it’s crucial to take immediate action. In many cases, the culprits behind these issues are the A and B valves. Here’s a step-by-step guide on what to do:
- Check A and B Valves: Begin by inspecting the A and B valves, as they are often the root cause of transmission solenoid problems. Use a voltmeter to check for the correct resistances, which should read 12 ohms for the A valve and 5 ohms for the B valve. If these resistances are not met, consider replacing the valves.
- Replace Transmission Fluid: Replacing the transmission fluid is essential, as contaminated or old fluid can contribute to solenoid issues.
- Clean the Pressure Switch: Remove and thoroughly clean the pressure switch before reinstalling it. This step can help resolve some solenoid-related problems.
- Seek Professional Help: If the issues persist after these initial steps, it’s advisable to consult a qualified mechanic. They will assess the transmission system by raising your vehicle and inspecting it visually. If necessary, they can remove and replace the faulty transmission solenoid.
- Consider Replacement: In some cases, replacing the entire transmission may be the best solution. You have the option to choose between a used or remanufactured transmission. Alternatively, you can opt to rebuild the transmission, though this tends to be a costlier option.
It’s essential to note that transmission problems may also stem from issues with the control module, valve body, shift solenoid, or wiring harness, rather than the transmission solenoid itself.
Is Replacing a Faulty Honda CRV Transmission Solenoid Expensive?
The cost of replacing a bad Honda CRV transmission solenoid can vary depending on several factors:
- Solenoid Replacement: If only one solenoid needs replacement, the job typically takes 2-4 hours of labor, with labor rates ranging from $60 to $100 per hour. Therefore, the cost for a solenoid replacement usually falls between $150 (minimum) to $400 (maximum). The specific model of your vehicle may impact the final cost.
- Solenoid Pack: If you need to replace multiple solenoids as part of a pack, costs can range from $50 to $300.
- Transmission Replacement: If you decide to replace the entire transmission system, expect a more substantial investment. This job usually takes around 10 hours of labor, with labor costs ranging from $500 to $1,200 in total. Additionally, the cost of a used transmission typically ranges from $800 to $1,000, depending on what the junkyard offers. Rebuilding the transmission is a pricier option, usually falling between $1,100 and $2,800 for the entire transmission.
How Often Should You Inspect or Service the Honda CRV Transmission Solenoid?
Generally, you should consider inspecting or servicing the transmission solenoid if you notice erratic shifting, gear jumping, or downshifting issues. However, as a general guideline, a transmission should last between 130,000 to 180,000 miles before requiring significant attention.
If you tend to shift forcefully or experience any of the aforementioned symptoms, it’s advisable to check the solenoid more frequently, perhaps once a week. Regularly using clean transmission fluid and practicing proper shifting techniques can also contribute to the health and longevity of the transmission solenoid.
Final Thoughts
Transmission problems are a common issue for Honda CRVs, and unfortunately, they have not significantly improved over time. Dealing with these issues can be expensive and often requires professional intervention. Continuing to drive a vehicle with unresolved transmission problems can be unsafe, so it’s recommended to consider getting a new car if these issues persist.
