What are the DTC codes related to Ford F-150 transmission problems?
P0766 – Failed Shift Solenoid D – This DTC can be stored when there is a problem with a shift solenoid or the valve body.
P2703 – Failed Friction Element D – This trouble code can be triggered by a failed friction element like a clutch disc.
P0720 – Failed Input Speed Sensor or Output Speed Sensor – This trouble code is caused by a bad speed sensor on the transmission.
P0730 – Incorrect Gear Ratio – This issue could be caused by a number of problems, including a fault in the transmission control module, dirty transmission fluid, or a bad transmission solenoid.
P0657 – Voltage Problem in the ‘A’ Circuit – This 5R110W transmission problem is often caused by a short, or bad ground on the PCM or PCM wiring harness.
P0700 – Malfunction in the transmission control system – This DTC is often triggered when there is a problem with the TCM, a wiring harness, a solenoid, or the valve body.
P0715 – Input/Turbine Speed Sensor Malfunction – This code typically gets stored when the input sensor cannot read the engine RPM, which can prevent the transmission from appropriately shifting gears.
P0717 – Input/Turbine Speed Sensor No Signal – This trouble code is generated when the PCM does not get a signal from the input speed sensor, which will prevent the computer from being able to determine when the transmission needs to shift.
P0791 – Intermediate Shaft Speed Sensor ‘A’ Circuit – This error can occur when there is a problem with the 5R110W intermediate shaft speed sensor, most likely due to a bad sensor, wiring problem, or a failed shift solenoid.
P0793 – Intermediate Shaft Speed Sensor Circuit No Signal – The computer will generate this DTC when it cannot communicate with the intermediate shaft speed sensor.
Tow/Haul Light Flashing – A flashing Tow Haul light on the Ford F-250 Super Duty acts as sort of a warning light to let you know that something is wrong with your 5R110W transmission. It can be as simple as a failed temperature sensor, or the valve body could be cracked in half. But you won’t know unless there was a DTC stored in the computer.
Recalls & Known F150 Transmission Problems
2011-2012 F-150 Reverse Gear Engagement and/or Lighting Issues (NHTSA Recall Number: 12V190000)
Ford had to recall 10,500 units of the 2011-2012 Ford F-150, to fix a faulty sensor called the Transmission Range Sensor, or TRS. Sometimes referred to as the Neutral Safety Switch, this sensor monitors the gearshift lever, and tells the Powertrain Control Module what gear you’ve just selected. Except on those 10k trucks, where the TRS wasn’t properly calibrated to the Reverse gear.
If you have one of the recalled F-150’s, that defective TRS is going to do one of two things. Number 1: The transmission range sensor isn’t going to recognize that you’ve shifted into reverse. So it’s not going to tell the PCM to engage reverse, and you go nowhere. Number 2: The TRS sees that you’ve shifted into reverse, it emails the PCM and tells it to activate reverse, but it forgets to CC the backup lights and the little ‘R’ light on the dash. If this happens, you could inadvertently back over somebody in a parking lot, because they didn’t see your reverse lights (that would be bad).
In 2012, Ford instructed its dealers to inspect and replace faulty TRS sensors on affected 2011-2012 F150 models. If you’re experiencing this problem, or are unsure if the recall repair was performed on your F-150, you can call Ford Customer Service at 1-866-436-7332. Have your VIN number handy, and refer to this Ford recall campaign number: 12C23
2012 F-150 Shifter May Be Moved Out of Park Without Pressing the Brake Pedal (NHTSA Recall Number: 11V582000)
Ford recalled 16,091 units of the 2011 Ford F150, to replace a defective brake shift interlock switch. This little device is designed to prevent the shifter from being moved out of Park unless the brake pedal is depressed.
If the brake shift interlock switch isn’t working properly, the shifter will be able to move out of park, without the brake pedal being depressed. Should this happen, the truck could instantly lunge forward or backward, causing an accident with another vehicle or striking a pedestrian walking by (again, that would be very bad).
In 2011, Ford instructed its dealers to inspect and replace faulty brake shift interlock switch on affected 2011 F150 models. If you’re experiencing this problem, or are unsure if the recall repair was performed on your truck, you can call Ford Customer Service at 1-866-436-7332. Have your VIN number handy, and refer to this Ford recall campaign number: 11C21
Can I drive with a transmission problem?
Okay, if your truck can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a F150 transmission need to be replaced?
The overall lifespan of a Ford F-150 transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the OE Ford F-150 transmission last for between 130,000-220,000 miles. A high quality replacement Ford transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Ford F150 SD transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Ford F150 transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your F150 to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Ford F150 transmission replaced?
In order to replace your Ford F-150 transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, the ECU will have to be reprogrammed to accept the new gearbox.

How to Solve Ford F150 Transmission Problems
Solution A: Buy a Used Ford F150 Transmission
The quickest way to fix your transmission problems is to simply buy a used 4R100 or used 4R75E transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Ford F150 Transmission
Another option would be a rebuilt 4R75W or 4R100 transmission or rebuilt 4R70W transmission. A local repair shop will remove your F150 transmission, then install a bunch of new parts. The problem here is, the skills and experience of each mechanic will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Ford F150 Transmission
Many owners depend on their Ford F-150 to make a living and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.
