Hi there, thanks for writing in about your 2004 Ford F-150. Check the transmission fluid level. Changing the fluid filter may help temporarily but it sounds like the clutch packs in your transmission may be worn to the point of needing replacement. Have a professional inspect the gear issue to verify the faulty component and have this taken care of properly.

Sometimes, the problem can be as simple as a bad transmission pan gasket, but it can also be faulty seals, ruptured fluid lines, a leak in the pan or a crack in the torque converter.
The fact that you feel the truck wanting to move (slipping) strongly suggests an internal mechanical/hydraulic problem, not an external control issue. The fault may be in the reverse clutch assembly, low/reverse band, low reverse/servo, or an obstruction in a number of hydraulic circuits.
The primary cause of slipping in a manual transmission is a damaged clutch. In an automatic transmission, including the Ford F-150 transmission, issues can be caused by; Broken gear bands. Gear wear and tear.
What is the fix for a slipping transmission? It`s simple. Just pop the hood of your vehicle, locate the transmission switch, and change the setting from “SLIP” to “STABLE” . . . If only it were that easy.
Possible causes of no overdrive include a faulty transmission range switch, valve body, faulty overdrive brake, or faulty ECM. Faults codes should be read out with a scanner, and statuses read.
In an automatic transmission, slipping can be caused by wear and tear on numerous different parts. These include damaged or worn clutch plates, transmission bands, and solenoid packs. If your automatic transmission has been slipping, it`s likely a technician will replace some or all of these parts to fix the problem.
The Turbine Shaft Sensor measures input shaft speed. The PCM uses the information provided by the TSS to determine whether or not the transmission is slipping.
Powertrain issues, problems, and complaints are some of the most common concerns that owners of 2021 Ford F-150 trucks have been experienced. Some of the most frequently reported issues include problems with the transmission, engine trouble, and difficulty with the four-wheel drive system.
However, just like buying any used vehicle—there are risks involved. Even in models that are well built and popular such as the F-150 model. One example of Ford F-150 models you should be wary of are those from 2009-2014 that are known for suffering from transmission cooler line fatigue and rusting.
This means that it is not shifting smoothly from gear to gear or that it is not staying fully in gear as you drive. This can be the sign of internal damage or it may just mean you are due for a standard transmission service to replace the transmission fluid, filter and pan gasket.
A slipping transmission means that it is struggling to shift between gears and/or stay in gear. It could be the sign of a major transmission problem or you may just need minor transmission maintenance.
This includes speed sensors that tell your transmission how and when to change gears. If your speed sensor is sending incorrect data, it can lead to hard shifting and other drivability problems.
With an automatic transmission, overdrive is most often an intuitive function initiated by the ECU when the vehicle reaches the proper speed. In the case of manual transmissions, overdrive is the highest gear of the transmission but has to be engaged by the driver.
This is often due to issues with the fluid, clutch, torque converter, gears or solenoid. Once you`ve checked your transmission fluid levels, bring your car in to a repair shop for further analysis.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.

Low transmission fluid will eventually lead to overheating, which can cause catastrophic damage. Overheating can also lead to a lack of hydraulic pressure in your transmission, which could cause your transmission to slip and struggle when it tries to engage and change from one gear to the next.
When there`s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won`t control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
Any time a battery is disconnected, or in your case a transmission is replaced, it can take up to 90 days for the engine and transmission computer to relearn your driving habits. It`s normal for an automatic transmission not to shift into higher gears until the engine coolant temperature is at a specified temperature.
What years did the 5.4 Triton have problems? Based on my research, 5.4 Triton engines from vehicles manufactured between 2004 and 2013 seem to have the most problems. The earlier engines didn`t seem to have as many issues, nor do the ones produced after 2013.
Specifically, the 2018 F-150 is easily one of the best and most reliable models of pickup trucks, thanks to its high durability ratings and great mileage. The 2019 model is also a standout with excellent critics and user reviews.
Ford`s PowerShift dual clutch transmission was used in 2010. Vehicles impacted are the Ford Fiesta (model years 2011-2016) and the Ford Focus (model years 2012-2016) equipped with a PowerShift transmission.
