Both GM and Ford have made statements regarding the fact that while the physical transmission was designed jointly, programming of the transmission will be unique to each manufacturer and therefore their respective powertrain configurations will not necessarily be reminiscent of each other with regard to shift strategies. The 10R80 features 10 forward speeds, 3 of which are overdrive ratios. It's deep 4.69 to 1 first gear ratio is the lowest in its class and it features a relatively tall 0.63 to 1 final overdrive ratio.
An integrated electric transmission fluid pump permits the 'start-stop' feature with minimal delay. Like the six speed 6R80, the 10R80 features three driving modes - 'Tow Haul', 'Sport', and 'Normal', with each driving mode modifying the shift schedule and characteristics to compliment particular forms of driving behavior. Because the transmission features 10 forward speeds performance and, more importantly, fuel economy is maximized by the transmission's ability to select an ideal ratio for current driving conditions, such as engine speed, load, and vehicle speed.
The final installment in the C6 series, the 4R100 acted as an upgrade to the E4OD by providing various changes to the internal components in order to increase the level of durability when put behind the stronger engines introduced around that time, such as the Powerstroke Diesel Engine.
The 10R80 became standard on the 2017 F-150 equipped with the 3.5L EcoBoost (Raptor and standard models). As of the 2018 model year, the 10R80 is standard with all engines except the standard 3.3L Ti-VCT V-6 (2.7L EcoBoost, 3.5L EcoBoost, 5.0L V-8, and 3.0L Power Stroke diesel). A stacked numerical (1 through 10) readout in the gauge cluster identifies the currently selected gear ratio in real time.

A vehicle is made with numerous software and hardware components. Amongst them, the gear box or transmission plays an essential part in the function of the car, just like the brain and heart in our body. Without a transmission, the engine would not be able to deliver power to the wheels.
Ford 4r100 Transmission
In general, there are 2 types of transmission: automatic and manual. The manual device is managed by the user and have a gear selector as well as clutch assembly to adjust levels of gear.
Therefore, you can control the selected gear completely. These days, most car models it made with an automatic system of transmission, which applies a torque converter instead of clutches to change gears automatically without manual effort.
4R100 is a heavy-duty automatic transmission that is introduced in 1998 by Ford. In fact, it is an updated version of the predecessor E4OD. This system is an essential part in several of the most popular Ford cars such as Ford Excursion, Ford Expedition, Ford Super Duty, Ford Lightning and Ford E-series.
When you expose a 4R100 transmission to increased torque load and overload, its operation would be weakened. In this article, we will show you some common problems in 4R100 transmission and also several according solutions that you can do yourself without the need to call a professional mechanic.

Problems in 4R100 Transmission
The first thing you need to do is finding out what is wrong with the 4R100 transmission to have suitable solution. The following are some common issues happening in the 4R100:
- Slipping the transmission off when shifting gears.
- Fluid leakage from the front part of the transmission.
- Hard shift in the gears.
- Car stalls in reverse.
- Transmission only works in reverse.
Solutions for 4R100 Transmission Issues
If you have any problems with the 4R100 transmission mentioned above, then the following solutions would help to deal with them:
1. Transmission Slipping When Shifting Gear
When the gears are not shifted properly by the transmission, do the belowing steps.
- Check the alignment of DTR sensor to see whether it slips, it would be a cause for the delay in transmission response in your vehicle.
- Check the overdrive light to see if it flashes. In this situation, the problem would be from the transmission’s solenoid. This is a serious problem and requires rebuilding, which could save you a lot of money. However, this task requires specialized skills, so you should have it done by a professional mechanic.
2. Fluid Leakage from The Transmission
When you face a fluid leakage in the transmission, it is important to check the following parts:
- Front seal: If you have not used the car for a long time, then the seal would possibly dry up and get brittle. As a result, the seal would lose its elasticity and ability to keep the liquid, which leads to the leakage.
- Hub of the torque converter: This component would worn out due to constant use of your car, which requires replacement of the transmission or the torque converter.
In both cases, you need to replace the transmission with an already used one, which would be found with cheaper price.
3. HardShift in The Gears
If you are dealing with a hard shift in the gears, then the accumulator would be broken or stuck in the bone. In this case, you should remove it carefully from the transmission, and see if there is any marks of wear at the bore.
Use a dry and soft cloth to clean it, then check whether the grooves in the accumulator are damaged or not clogged.
Another possible cause would be because of a faulty line modulator valve. You would see it show up at other gears if the problem happens. To fix this, you need to replace with a new one.
4. Vehicle Stalls While Reversing
This issue would be the result of malfunction in IAC or Idle Air Control sensor, which is often built in modern vehicle models to control the idling RPM of the engine.
This device could last for lifetime of your car, thus the premature failure is probably due to complete or partial jamming in the actuator, which could not control smoothly and lead to frequent stall of the engine.
In most situations, you can resolve this problem by removing and cleaning the IAC sensor. But if this does not work, then you need to replace the actuator or the IAC sensor.
5. Transmission Only Works in Reverse
When facing this problem, you should examine the forward clutch assembly to see if it is worn out. In addition, remember to check the splines in the forward planetary. Both cases require to replace the transmission.
A re-manufactured or rebuilt transmission has all required upgrades and necessary major alterations, which are made to improve its durability and performance.
If you buy a 4R100 transmission that is re-manufactured from a famous brand, then you can have a warranty of nearly 3 years instead of a 90 days. The company also provides complete replacement of the transmission when it fails to work normally during this warranty period.
Conclusion
Ford 4r100 Transmission Case
After reading this article, we believe that you have learned all necessary information to deal with common problems in 4R100 transmission.
Once you have mastered in rebuilding the transmission, it becomes much easier to add the features as an improvement, which eventually enhances its performance. In addition, you can also increase the efficiency by installing a transmission cooler to regulate the temperature in the transmission.
To get maximum performance from the 4R100 transmission, you need to manually check its components and operation frequently. Figuring out any problems early could help to solve it timely, which does not seriously affect the performance of the car.
