Same thing happened to me I replaced the fuse for the automatic transmission. I believe it was a 15amp fuse and it’s located in the fuse box that’s under the hood in the engine compartment

Problems with the automatic transmission

Ford F-150 2007  111600 miles
When the truck warms up and stops, when you try to start it again it takes like 10 seconds before engaging in drive, and in high revolutions there is a thumping between gears. It started happening right after cleaning the radiator.

Automatic transmission failure

Ford F-150 2004  105000 miles
When I'm driving my truck at around 30 miles per hour, it accelerates as if it was in neutral and goes up to 3500rpm, and then it suddenly changes gears. The gearbox was already dismantled and repaired, but it continues with the same problem. It was also tested with another computer. The weird thing is that if I start accelerating from the beginning with the overdrive on there is no failure, it works perfectly. Any ideas?

The most likely cause are the poppet valves, something may be scratched and it gets stuck, that's why it delays changing gears.

Battery drain SolvedSolved

Ford F-150 2011 Super Crew/5.0L Flex V8 191720 miles
Battery drain, I can put in a new fully charged battery in use the truck for a couple of days as normal. Normal driving distance is less than 60 miles to and from my work site and to a few other places through out the day. By 3rd morning I have to use a jump starter to start the truck. The truck starts fine through out the day. The next morning I have to use jump starter again. I've checked relays, replaced some old cracked fuses in the engine fuse box, disconnected a reese tow unit that I don't use anyways. Found a faulty wiring harness in the left rear driver door, replaced that also. I've not had time with work, and the horrible weather to do much on checking all of the fuses.

Update, worked on blower speed problem. Pulled and tested blower motor and speed selector resistor controller. Controller is defective. Been testing all afternoon, the truck starts, on a very weak battery, sometimes it takes a few tries and a couple minutes of waiting and it starts.
Henry from United States 2 years ago
Put a new controller on, however, it was not new. Got some bad controller that someone returned as good. The store clerks didn't check the return. However, they did swap with me. Got a good controller but have a truck that doesn't start. Waiting for warm days. The drain isn't my blower or temp controller. I think it is the starter or starter ground.
Johnnybjohnny from United States 2 years ago
Similar problem. Everything off yet the blower motor still works without keys and dash gauges move up and down as well as the odometer comes on and off. It like there are current spikes happening. Drains battery within about 3 hours have to jump start it.
Henry from United States 2 years ago
That sounds like a relay locked on for the blower. The rest sounds like loose or bad grounds. Check all ground points you can see, and rust, or corrosion wires clean off. With these new trucks could be anything. I saw one ford with a drain that was bad. The exterior lights, and headlights would come on by themselves intermittently and it was corrosion on two pins in a wire harness not being used inside the dash.
Johnnybjohnny from United States 2 years ago
@HenryThank you for the reply. I’ll see what I can do.
Henry from United States 2 years ago
@JohnnybjohnnyIf you haven't done so, you can check on this site for diagrams of fuse and relay boxes for your ford. Best of luck on fixing your problem.

New Problem - no start, battery good. Truck will start if leave key in ignition for a minute or two and then it cranks. Replaced starter, original starter, badly rusted. Starter had 192K on it. This has the no start issue. Going to swap around relays for starter, and planning on replacing FPDM in rear. Starter was not easy to replace.

Henry from United States a year ago
Issue with Battery Drain, and fail to crank until after a few minutes with key in ignition. Battery Drain was two items - Rusted Starter - Replaced.
Fail to Crank - was Transmissions Shifter Position Sensor. The shifter sensor on the 5.0 V8 Flex is in the transmission. The sensor was failing, and telling the computer that the truck was already in gear. Cars in gear will not start. Cars in Park or Neutral will start. I was told there was something known about this in Ford Tech bulletin or service manual. It would be simple for them to print it in the owners manual.
Steel from United States 10 months ago
Same issue, but I dont get three days, usually overnight. I did notice that when in Park the P is not orange like all other gears. I was told PCM board, faulty transmission cable either at the top of transmission or in the steering column.

Truck failure

Ford F-150 2008  128 miles
It was working fine and the next day I used it I felt the truck heavy, it didn't have the normal acceleration, and then I realized it didn't have the power to go uphill, it went sluggishly and when the revolutions go up it started shuddering. With the scanner it showed errors P0755, P1747 and P0743, I was told it might be the gas pump, but the failure continues. It's a 2008 mexican Ford truck, 8 cilinders and 4.6L engine with automatic transmission.

The error code P1747 ir related to the transmission: pressure in the control solenoid, and most likely the other error codes are related. Check the solenoids.

How many miles since last transmission fluid exchange? Shuttering sound like torque converter shutter. Try BG Products transmission conditioner, it will neutralize the fluid. If the shutter goes away then exchange the fluid and use another BG conditioner again.

There could be a number of reasons why this is occurring, and it will be necessary to diagnose the problem to determine the cause.
One potential cause could be a problem with the starter motor. If the starter motor is not functioning properly, it could cause the engine to not crank when the key is turned.
Another potential cause could be a problem with the starter relay. The starter relay is responsible for supplying power to the starter motor, and if it is not functioning properly, it could cause the starter motor to not engage when the key is turned.
It is also possible that there could be a problem with the ignition switch or the wiring for the starter system. If the ignition switch is not functioning properly, or if the wiring for the starter system is damaged or corroded, it could cause the engine to not crank when the key is turned.
I recommend having a mechanic diagnose the issue to determine the cause and recommend the appropriate repairs. They will be able to test the starter motor, starter relay, ignition switch, and the wiring for the starter system to identify any problems and make the necessary repairs.

Starting system fault no start

Ford F-150 2011 3.5L ecoboost 120000 miles
Put key in ignition and have power for dash etc but when try to start nothing happens.No crank at all. Starting system fault shows up,as well as advanced trac, brake system and oil change warning. The latter codes randomly showed up one day when driving. The starting system fault appeared when just sitting , not running, while trying to charge old battery. The battery said full and I tried starting it and fault appeared. Both factory keys/ fob do the same. I have a new battery ( did it on old battery too) I have tried disconnecting/ reconnecting battery. Have checked the fuses interior and in power distribution box as well as the ignition relay. Have made sure the connection in the inside fuse box is good. I have run out of things to check. Could it be pcm relay?

Battery and Radio issues...

Ford F-150 2012 F150 XLT 6.2L V8 178549 miles
1st my radio just quit one day few months back. Fuses are fine, according to repair shop radio is perfect, wiring perfect. They don't know what happened and I wasn't replacing my radio because I want music for over 900$. Then today(June 2022) my battery indicator light popped on, then five minutes later it popped off. Alternator fine, battery only a year old and reads fine, checked cables connecting battery and all are tight and where they are supposed to be. I cannot figure out why my battery light is popping on. And as far as I can tell while driving I am not losing power. 2012 f150 xlt with almost 200k miles and now everything wants to start going wrong. Any suggestions on what else I should check for battery issues and radio issues since everything seems to be checking out perfect?

Gearbox failure

Ford F-150 1997  246000 miles
It makes the switch from first to second gear at very high revolutions or only when I take the foot off the pedal, and it doesn't downshift or it does it very harshly, sometimes going over 6000rpm. I've been told it's the "gearbox governor", does anybody know where it is or how to fix it?
