We Found 7 Ford F150 Transmission Solenoid Problems!

What are the common problems Ford F150 transmission solenoid has? If you own a Ford F150, you probably know the answer. And we’re sure those problems bother you every now and then. But from now on, they won’t be a headache for you as we’ve come up with solutions.

The most common Ford F150 transmission solenoid problems are harshness in gear shifting. Also, the car doesn’t approach downshift from time to time. And if you face these on the road, that may cause serious accidents.

So let’s move on to their reasons and solutions in particular.

Ford F150 Transmission Solenoid Problems with Their Reasons

Knowing the reasons for every problem will make things easier to find solutions. Here you’ll know the reasons for the issues you face with the ford f150 now and then.

Failure in shifting gearFaulty sensor
Lack of power after the 1-2 shiftIncorrect size of check ball inside the valve
Poor Engine PerformanceSticking solenoid regulator valve
Forward gears slippingDamaged clutch
Unusual vibration and noisePlanetary gear assembly failure
Delayed forward/reverse gear engagementInternal seals become hard
Harsh or delayed shiftingLow transmission fluid

As you get to know what are the reasons for all the Ford F150 transmission issues, we can approach the solutions now. Scroll down and learn the proper solutions for every problem.

Detailed Discussion for 7 Transmission Solenoid Problems

Pick the right transmission for the right model will save you from transmission issues. Regularly updating the ECU and powertrain control module and cleaning the regulator valve will prevent some problems from occurring. Yet, in case any difficulties arise, we specify the answers for every situation.

Problem 01: Gear Shifting

Delayed or abrupt gear changing is one of the most common Ford F150 transmission speed sensor problems. The faulty transmission is assumed to be the reason behind it. When it happens, the backup lamp doesn’t function, and the PRNDL indicator won’t display the reverse. The 2017-2018 Ford F-150 and 2018 Ford Expedition are usually the main victim of this issue. 

Solution: Turning on and off the power sometimes solves the problem. And if it doesn’t work, you may have to change your transmission.

Problem 02: TCC Application Fails In 2nd gear

Torque Converter Clutch failure is one of the most experienced 2006 Ford F150 transmission solenoid problems. In this case, the vehicle doesn’t get enough power in 1st and 2nd gears. The incorrect size of the check ball placed inside the valve is the main culprit for this issue.

Solution: Replacing the check ball will solve the problem.

Problem 03: Poor Engine Performance

A clogged or sticky regulator valve causes it to happen. Dirty or contaminated transmission fluid also makes the solenoid regulator valve sticky. Sluggish acceleration is the main symptom of this issue. Overlooking the problem may sometimes cause coil failure or burnout.

Solution: Repair the solenoid regulator valve. If it doesn’t work, then replace the whole valve body.

Problem 04: Slipping Gears

When you press the accelerator, gear slipping happens if the transmission isn’t well connected to the engine. It occurs when the clutch loses its grip intermittently. It’s a risky situation you may face. Sometimes, overheating may result in this problem.

Besides, slipping gear is another root cause of 2001 ford f150 transmission solenoid problems. And if you find no leak be sure the solenoid is at fault.

Solution: In this case, if replacing the solenoid pack does not solve the issue, update ECU with program 06B06 and replace the forward clutch drum.

Problem 05: Unusual Vibration And Noise

If you aren’t overloaded and still hearing unusual noises, then it’s probably the planetary gear assembly failure. Slipping or loss of reverse gear, grinding noise, and vibration is all you’ll experience if this happens. And sometimes, it happens if the power steering fluid is low.

Solution: If it’s because of low steering fluid, then find out a leak under the engine and fix it. If it’s because of planetary gear assembly, install the planetary upgrade kit with a new torque converter.

Problem 06: Delayed In Gear Engagement

Delaying in shifting on front and reverse gear is one of the many Ford F150 shift solenoid symptoms. Usually, you may experience it after a cold start in cold weather. Hard internal seals and jammed oil regulator valves are the reason behind it. It may seem like a minor problem, but it can cause major damage if you overlook it.

Solution: Install a new front pump adapter seal and separator plate. And clean the regulator valve and its bore.

Problem 07: Harsh Shifting From Gear 3 to 4

You may feel hardship in gear changing due to low transmission fluid. A trouble code will appear at this, and you may have to update the powertrain control module. It usually happens when you shift gear from 3 to 4. Broken overdrive servo rings or piston ‘E’ clips are often the main culprits.

Solution: Update the powertrain control module with new software.

What Are the Signs of A Bad Transmission Solenoid

If you don’t experience any major problems and still want to know whether your transmission solenoid is good, then this part of the content is for you. From here, you’ll know how to determine a bad transmission solenoid.

Here are the top symptoms you may feel in your car if the transmission is falling.

  • You’ll feel a delay or a sense of slipping and pooling when you try to shift between gears.
  • As you try to slow down, the vehicle won’t respond. It won’t downshift, and the engine will rev whenever you press the brake.
  • The check engine light will come on as the electrical system will notice a failure.
  • The solenoid won’t be open enough and receive signals to shift transmission. And the transmission will not go neutral.
  • Gear shifting will become an issue of vibration as it’ll be rough and erratic whenever you accelerate, decelerate, or shift gears.

Frequently Asked Questions (FAQs)

What causes shift solenoid failure?

A: Dirty fluid or an electrical issue causes the shift solenoid to fail. Even a minor change in the transmission fluid pressure causes numerous shift solenoid problems, including delayed shifting, obstacles on downshift, unusual vibration, etc.

What does transmission control solenoid do?

A transmission control solenoid usually controls the vehicle. It receives the electrical signal and controls the transmission fluid by opening and closing. In appearance, it is just a small valve.

Will a bad solenoid throw a code?

Yes. A bad solenoid usually throws a trouble code. It’s the most common symptom of a bad solenoid. And if you overlook it, it may lead your vehicle to major damages such as driving in the wrong gear or sudden burnout.


Having the Ford F150 transmission solenoid problems will turn the check engine light on most times. So, even if you don’t get the symptoms, the light will remind you if something goes wrong.

However, you’ll experience rigidness while shifting gears and moving to reverse gear. Also, unusual noises and sluggishness in running the vehicle will be a typical case if your transmission solenoid falls.

But as you know what to do in these circumstances, we believe nothing will bother you as much as it used to be. So, be careful and conscious. Happy Driving!
