Ford F150 Transmission- Problems and Solutions
First, let’s discuss all the problems, their symptoms, and solution briefly in the table:
|Broken Gear Bands||Grinding or scratching sound, slipping transmission||Replace Gear Bands|
|Failing Torque converter||Sluggish transmission, gears slipping or not shifting, transmission overheating||Repair/Replace Torque converter|
|Transmission Fluid Leak||Fluid leaks, fluid marks on the ground, low fluid level||Fix Fluid Leaks|
|Low/ Burnt Transmission Fluid||Low: clunking sound, gear slipping, engaging and accelerating slowly.|
Burnt: burnt smell
|Refill/ Replace Transmission Fluid|
|Longer Gear Shifting Time||Stuck or skipping gears, inability to upshift/downshift||Replace clutch/ Shift Solenoid/ TCM|
|Faulty Transmission Sensor||Locked gear, gear doesn’t shift from neutral, shifts to wrong gear.||Replace Transmission sensor|
Now, let’s discuss them in detail.
Broken Gear Bands
If the gear bands in your transmission are broken, it’ll cause problems. While shifting gears you’ll hear a loud grinding or scratching sound. The transmission will slip. The bands can break simply because they are worn out or adjusted too tightly.
Replace Gear Bands
If the transmission band is broken, you’ll need to replace it. This is a complicated process. You’ll need to remove quite some parts to just access the bands. So, it’s recommended to contact a mechanic.
A new transmission band may cost you about $70-$130. Of course, there’ll be added labor costs for the replacement.
Failing Torque Converter
A torque converter can fail due to excessive friction, faulty seal, or clutch solenoid. Bad transmission fluid might also harm the torque converter.
If you have a faulty torque converter, the transmission will feel more sluggish. The gears will slip or won’t shift. Your transmission will also overheat.
Repair Torque Converter
Sometimes, just flushing your torque converter is enough to fix it. For that, first, remove the metal guard underneath the front of the vehicle. Then, locate the supply line to your torque converter. Check your manual to determine the supply line.
Now, put an oil pan under the supply line. Put the vehicle in neutral and start the engine. Get an assistant to shift the gears while you add new transmission oil to the truck. This drains out the old transmission oil and fills the transmission and converter with new oil.
If you decide to get it flushed through a mechanic, it’ll cost about $100-$200. It depends on the size of the vehicle.
Replace Torque Converter
The toughest part of replacing a torque converter is removing the transmission from your vehicle. Once you’ve done that, just follow these simple steps:
Step 1: Hold the torque converter and jiggle it up and down while pulling it. It’ll easily come out.
Step 2: Take your new torque converter. Take some transmission fluid and apply it to the outer surface of the converter connection line. Then fill up the torque converter with transmission fluid.
Step 3: Next, take the converter and place it in the transmission. Hold the bottom side and rotate it while pushing it in. When it’s installed properly, the converter will spin without getting out. The studs of the converter will be within the transmission plane.

You can also get it replaced by a professional. It’ll cost about $600-$1000 including the labor costs.
Transmission Fluid Leaks
If the torque pump cracks or the axle seal becomes compromised, transmission fluid can leak out. The transmission fluid line can also get damaged over time and thus, leak.
You can confirm it by looking beneath the car for fluid leaks.
There’ll be spots on the ground. You can check the transmission fluid level with the dipstick. If the fluid is leaking, obviously it’ll be lower than normal.
Fix Fluid leaks
Finding the fluid leak and fixing it is a complicated process. Here, you should consult a professional. It might take as little as $150 to as much as $1000 to fix the leak. It depends on how much work needs to be done.
But, if you’re confident in your skills, watch this video for instructions and fix it yourself:
We also have a temporary fix for you. You can use CRC Trans-X Transmission Stop Leak & Tune Up to fix the leak. Pour the entire bottle of this with your transmission fluid. Be sure that it doesn’t exceed the maximum capacity of your Ford F-150.
Although, it can’t be used in CVT and manual transmission vehicles.
Low/ Burnt Transmission Fluid
The transmission may malfunction if the transmission fluid is low or burnt. The transmission fluid gets burnt in exposure to high temperatures, high mileage, and contamination.
If the transmission fluid is low, you’ll hear a clunking sound from the vehicle. The gears will slip and engage slowly. The vehicle will accelerate slowly. If the fluid is burnt, you’ll notice a burning smell while driving.
Refill/Replace Transmission Fluid
If the transmission fluid is low, you’ll have to refill it. On the other hand, if the fluid is burnt, you’ll have to replace it. It’s a fairly easy process. Still, you can watch this video if you need some help:
Longer Gear Shifting Time
Another problem people face with the Ford F-150 is longer gear shifting time. It happens because of worn clutches, malfunctioning shift solenoids, and faulty TCM. Other than worn clutches, shift solenoids, and TCM might malfunction due to electrical issues.
If the shift solenoids malfunction, the gears will get stuck or skip. You’ll be unable to upshift/downshift. These symptoms are also true for faulty TCM and worn clutches. Also, for faulty TCMs, you’ll face lower fuel economy.
With worn clutches, you’ll also require higher RPMs. The clutch pedal will feel soft/sinking.
You’ll have to remove the transmission to replace the clutch which is the hard part. But, if you are able to do it, the rest is pretty easy.
Here, unbolt the clutch plate and pry it off. You’ll be able to pull the clutch pieces out. Get your new clutch kit. Put some grease from the kit on the spline and then put it in the clutch. Bolt in the clutch. Put on the new throw rod bearing and bolt the clutch tightly.
Now, you’ll just have to wiggle the transmission to fit the clutch on. You can also watch this video for details: Ford F150 | Clutch Replacement | Making a Trans Jack Useful | Broken Stuff
If you choose to get it replaced by professionals, it’ll take about $1253-$1428.
Replace Shift Solenoid
Replacing the shift solenoid is pretty easy. First, you’ll have to remove the transmission pan. You’ll be able to see the old solenoid. Disconnect the solenoid connector. Remove the bolt of the solenoid. Then you can wiggle and pull out the old solenoid.
Now, take the new solenoid. Put some new transmission oil around the solenoid’s o ring and put it in. Attach the bolt and reconnect the connector. With that, the shift solenoid is replaced.
Also, it’ll cost about $200-$500 per solenoid to replace it with professional help.
To replace the TCM, first, you’ll have to access it. Here, you might need to remove the auto cap. The TCM module isn’t bolted. Just pull it out and disconnect the wiring from the module. Take the new TCM module. Reconnect it and put it in. And, you’re done.
If some of the locations don’t match with F150, refer to your driver manual. You can also contact a mechanic who’ll replace it for $750-$808.
Faulty Transmission Sensor
Some users may face a faulty transmission sensor. It’ll give the code P0705 upon diagnosis. Sometimes it may not show a code but be faulty. If you doubt that, physically test the transmission sensor. Rather than wearing out, it also goes bad due to wiring issues.
With a faulty transmission sensor, the transmission gets locked in gear. In Particular, the vehicle can’t move out of neutral. It may even shift to the wrong gear.
Replace Transmission Sensor
The solution here is to replace the transmission sensor. Just remove the connector of the sensor. Now, you can easily remove the sensor using a socket. If the sensor is stuck, use a prybar to take it off. Take your new sensor. Attach it and connect the connector.
Now, take your vehicle for a test drive. The problem should be fixed. You can also watch this video for help:
You can also get it replaced for $273-$372 with professional help.
