How many Toyota 4Runner transmission solenoid problems?
The transmission is a critical component of the vehicle’s operating system. An automobile gearbox’s structure is quite complex, with numerous mechanical elements. As a result, if the car is not properly maintained and operated while in use, the gearbox will be prone to faults.
The solenoids in the transmission aid in the transmission’s proper performance of its duties. They provide it the ability to change gears automatically as it receives data from the car’s computer. You will ultimately need to replace the solenoids because they will burn out or stop working properly.
Although Toyota 4Runners are known for lasting a long time, they also frequently experience transmission problems, especially beyond 100,000 miles.
The most common 4Runner owner complaint, particularly with reference to automatic transmissions, is wear and tear. So, in this post we will help you solve these Toyota 4Runner transmission solenoid problems.
Reasons For Toyota 4Runner Transmission Solenoid Problems
The transmission solenoid has a very long life. However, if the user abuses it, it will break faster than usual. Here are some of the reasons why the Transmission Solenoid fails the most frequently.
Issues with the Reverse Gear
When the reverse clutches wear out, the reverse gear engages slowly, slides, or doesn’t engage at all. A cracked sunshell or a fluid leak in the reverse hydraulic circuit are other potential reasons for this issue. While worn clutches or other broken parts necessitate the removal and repair or replacement of the transmission, certain fluid leak concerns may just need minor fixes.
Upshift Issues
It may be a sign that there is a problem with the throttle position sensor rather than the transmission if the transmission refuses to upshift or only does so when you remove the throttle. To enable proper shifting, the Throttle Position Sensor, which is situated at the engine throttle shaft, communicates information to the transmission. The Throttle Position Sensor is affordable and simple to replace.
Shift to Neutral When Stopping momentarily
Congestion in major cities is difficult to avoid. And if you have a habit of frequently going to Neutral, this is a major mistake that will cause the transmission solenoid to fail sooner.
Shift to Neutral When Heading Downhill
Many individuals have the tendency of shifting to Neutral gear when driving downhill because they believe it will conserve gas, but it actually does the reverse. Furthermore, this limits your capacity to drive the vehicle, putting you in danger in the event of an emergency.
At the same time, this tendency causes the gearbox in the car to deteriorate faster. If you don’t want to spend a lot of money on gearbox repairs, it’s time to break this practice.
Gasoline Level Is Too Low
The gasoline gauge isn’t always totally accurate, and the automobile can come to a halt if it runs out of fuel sooner than predicted.
Fuel also aids in the lubrication of system components. The lubricating capacity of your car is lowered when the gasoline level is too low. This is especially relevant for automobiles that employ transmission solenoids because they will impact transmission solenoids more quickly.
Wet Transmission Solenoid
Even a small bit of water entering the gearbox might completely damage it. If there is water in the gearbox, it is best to consult a garage that specializes in repairing car gearboxes so that the situation can be handled safely.
Signs Toyota 4runner Transmission Solenoid Problems
To quickly overcome your Toyota 4Runner transmission solenoid, you must pay attention to the following symptoms.
Irregular Gear Adjustments
One of the most common shifting solenoid issues is this one. You may encounter erratic or unexpected gear changing if this component of your car develops a malfunction.
The solenoids only open to allow the right amount of fluid to enter and close to prevent too much fluid from entering. But a blown transmission solenoid fuse or defective wiring in the solenoid can cause your car to change into gear unexpectedly.
This implies that you might suddenly shift into a higher gear, which would increase your car’s speed. When you’re trying to accelerate or pass a slower car, the gear may also move to a lower one.
As soon as you notice symptoms similar to these, you must seek the assistance of a transmission specialist. Ignoring it will only lead to more severe issues that are costly for both the owner and the vehicle.

Delay In Shifting
The force behind automatic transmission is pressure. This means that the solenoid regulates the internal pressure, which governs how a vehicle shifts into gear.
Consequently, solenoids have a limited lifespan. After being used consistently for a number of years, they age and begin to malfunction. At this point, shifting issues with the automobile transmission become apparent, especially if it takes longer than usual.
Your vehicle’s solenoid may be malfunctioning if shifting is taking longer than usual.
The solenoid may occasionally close or remain open as a result of soiled fluids inside of it. As a result, your car’s transmission may act strangely or operate more slowly than it should. Therefore, it is important to treat indications like these of a malfunctioning transmission relay.
Cannot Downshift
Occasionally, a solenoid issue with a car won’t impair acceleration or gear upshifting, but you’ll still have trouble downshifting, either slowly or with no downshift at all.
When your car’s transmission solenoid malfunctions and becomes jammed open, this is what occurs. Several factors could be at play here.
The solenoid’s internal wiring may first be the source of the issue. A solenoid with damaged wiring may be unable to receive electrical impulses, which keeps it open, forces it to take in additional fluid and pressure, and prevents it from downshifting.
A broken solenoid is another factor. These types of downshifting issues occur when the solenoid itself is destroyed. Additionally, the intake of contaminated fluid may cause your vehicle to be unresponsive to downshifting.
This means that an excessive inflow of contaminated or unclean fluid can make it harder to downshift by weakening the solenoid’s response to instructions from the transmission control module.
Check Engine Light Indication
You shouldn’t disregard the check engine light when it appears since it indicates that your engine has an issue that has to be fixed. The transmission of the car usually switches to safe mode while this light is on, making it harder for you to drive.
In situations like this, you would only be able to use a limited range of gears and power, which would be a clear indication that the car engine has a problem that requires immediate treatment. When this occurs, don’t be reluctant to contact a transmission specialist or a mechanic for assistance.
How To Diagnose Toyota 4Runner Transmission Solenoid Problems?
We must identify the issue and the area of the engine it originates from in order to diagnose the transmission solenoid problem. The internal wiring, the transmission control module, or another mechanical issue could all be to blame.
A transmission specialist may be contacted, or you may choose to perform the transmission shift solenoid test on your own. To do the latter, however, you’ll need to learn about trouble codes so that you can identify the precise issue with the vehicle.
If the trouble code indicates that there is an electrical fault, there most likely is a wiring issue. The majority of solenoid-related error codes can be quickly fixed by flushing the transmission or changing the transmission fluid.
It’s always worthwhile and reasonably priced to replenish the solenoid fluid or do a transmission flush.
For transmission solenoid diagnostics or troubleshooting, a scanner is crucial. You must locate a transmission diagram that displays the electrical layout in order to accomplish this.
The pins that connect to the malfunctioning solenoid must then be found. The transmission’s plug needs to be taken out. The malfunctioning shift solenoid can then be found using the scanner. You will learn more about the issue from the transmission shift solenoid test error codes.

How Much Will a New Transmission Solenoid for a 4Runner Cost?
Here is the crucial query. Minor component repairs (such as bushings) can be easily and affordably purchased and installed, but a complete transmission rebuild or replacement will take a lot of time and money.
You might need to go to a shop that has a transmission specialist on staff or that just focuses on transmission repairs as many technicians don’t have them available.
On the low end, the wait time to receive your 4Runner returned from the repair might be a week. Due to the strong demand for their transmission expertise, some people have had to wait three weeks or longer.
A rebuild or repair of your transmission will affect you financially. The typical price for a new transmission is $2,500. A 4Runner, though, might cost you more than usual. And although buying used transmissions could save you hundreds of dollars, it isn’t always the greatest choice.
Final Thoughts
Different indications of a bad Toyota 4Runner transmission solenoid can appear. As previously indicated, you can have trouble downshifting and encounter strange gear shifts either uphill or downwards.
If your vehicle solenoid malfunctions, your gear may potentially become stuck. When you start noticing these symptoms, your vehicle solenoid needs attention; don’t wait to address the issue. Bring your Toyota to the shop, and all issues will be resolved.
