Ford Super Duty (1999-2016) :: Transmission Jerks And Shutters While In Cruise Control
Nov 21, 2014
2008 Ford F350 5.0 with automatic transmission, extended cab, 2 wheel drive. While on the highway and in cruise control, and only when climbing a small incline, the transmission jerks and shutters. Feels like transmission starts to downshift, but then doesn't, back & forth. If climbing a much larger hill, the transmission downshifts just fine. Transmission shifts just fine while NOT in cruise control. Was thinking electronic module or sensor. Any specific information on the exact electronic part that may be faulty?

02 E450 Super Duty V10, C class a motorhome, 29000 miles. Cruise stopped working a month or so back. I searched this forum and managed to fix it with the info provided. It turned out to be the pressure switch on the master cylinder, the recall had been done. I replaced the pressure switch and the harness with an aftermarket one from the local auto parts store. It worked well for about 200 miles, it knocked off again on our road trip last week. It was working on the road and we stopped for breakfast and it didn't come on again, no light in the dash or anything.
When I ran the internal diagnostics on the first repair all the lights would flash when the buttons were pressed and the servo would cycle through at the end of the test as it should, based on the diagnostic instructions. This time when I run the diagnostic test the light will flash when I first turn the switch on (holding the off button down) and when I push the on the button but will not flash when I press the other 3 buttons.
I have not been able to find a wiring diagram for this particular truck, I've found 6 or so but none of them match my fuse boxes under the hood and dash.
I have no trouble lights on in the dash CEL or ABS. I'm at a loss what direction to take from here.

I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either.

My 1999 SD was originally a Work Truck without cruise. I'd like to add cruise of some sort (factory or after market), but also trying to keep the cost and difficulty factors low.
Have any of you SD drivers ever done this and if so, what you went through?

Suddenly my cruise control dropped out. With some investigation I'm pretty sure it's that sensor or switch stuck to on position. Brake light is on. Checked the brake system and everything works well. Fluid is full all 4 pads replaced 2 days ago. Plenty brake power.
The question is: how can I bypass that switch to get my cruise control back? I see 4 wires coming out of the switch: red, blue, green, red/orange, green/purple. How do I do it?

Just noticed today that my cruise control on/off button is sticking. Push to off it stays pushed off, push it up to on and it stays up so i must physically center it myself. Is there a way to remove the button and take it apart to clean and regrease the contacts so it doesnt stick? Kinda dumb actually since i might have used it eight or ten times since buying the truck new....

2010 f250 cc 5.4 145000 miles. I bought it last fall have not drove it a lot. When using the cruise control and a load is added grade or hill in the roadway. It jerks hesitates or miss then cleans up and runs fine. When using the accelerator it does not do this. No codes.... Thinking about changing the plugs.

Just bought the 03 listed in my signature line, and I just found out that the cruise control isn't working, so started trying to troubleshoot anything obvious.
When I switch it on, I get no cluster light that the manual shows to be to the right of the brake light. When I turn the key to run, it never lights up, so am guessing the bulb is bad.
Can't see how a bad bulb would keep the system from activating, so am thinking I have bigger issues. I pulled the fuse panel, but the manual does not have a listing for speed control. Which fuse it is combined into?
Also need the skinny on how to change the bulb. Can I reach my hand behind there? does the cluster have to come out?
Last question. What is the most likely culprit for non functioning cruise? A module? Perhaps the switch in the steering wheel?

Our cruise isn't working, I've read through the posts here and tried a few things
2000 F-250 V-10
-First symptom was the cruise light would light with the ON button and go off with the OFF button but I could not set the speed with the SET button. Now the cruise light hardly comes on at all any more.
- I've run the cruise self-test diagnostics and all the switch presses passed with no additional light blinks. After the static test the speed control servo makes a sound but does not move the throttle at all.
-The horn works
-Fuses are good
-Truck was taken to the dealer several years back for the cruise update. The pigtail with the green label is installed at the master cylinder. I've disconnected both connections and sprayed with contact cleaner.
That's about it. What it could be or what to test next?

I was driving home from school last week and noticed my cruise control would stay set for 5 minutes or so, then slowly (over several minutes) lose speed. I've noticed it happen before, but very infrequently and usually if I stopped to use the restroom, when I started the truck back up it was fine. This time it continued to happen.
As I was getting nearer to home, I noticed that while I had the cruise set, I would hear a high squeaking noise in the dash almost dead center under the radio. Then , when I would tap the brakes, there would be a rattle. This would only happen with the cruise set.
Noise in dash - YouTube
Not sure how well the squeak can be heard, but the rattle is definitely audible. What the cause might be? Electrical, mechanical, are the cruise and the noise even related? Other than that, the truck seems to be running alright.

I have a 2001 F-250 SD XLT with the ABS light on, cruise control doesnt work and the horn only works with the key out. The codes for the ABS is no signal input from the left and right front wheel sensors. No problem there. Also my speedo stops or jumps when I press the horn button while driving down the road. When I quit pressing the horn button the speedo works fine. So after looking over the posts on cruise control, etc. Does the rear speed sensor have anything to do with the cruise, horn not working? All fuses are good so I am thinking the cruise control switch on the master cylinder or a short in the steering wheel column or my ignition switch. What do you all think?

Just picked up a 99 F-350 V-10 today. Decently clean, works well. It'll be an occasional tow vehicle for hauling my car to car shows.
Anyhow, on the way home, I couldn't get the cruise control to work. I've read about the brake pressure switch problem before joining today. I can hit the on button and set it, and the cruise indicator lights up in the dash and will stay on, but will not hold the speed.
From what I've read, I can't seem to determine if the brake pressure switch will allow the light to come on or not. Should I be looking elsewhere for the problem?
Next fix - overhead console. That one seems simple.

Was hoping to get confirmation on a fix I intend to repair.
2000 F350 SuperDuty 7.3l Diesel 4x4
Cruise isn't working...... lights won't even come on and nothing happens at the switches.
This morning I put in a new airbag clockspring ...... just requires patience but not too hard to do.
That didn't resolve. Was going to put in new cruise switch at the brake master cylinder.
My question is would that part prevent the cruise control from even turning on at the steering wheel controls? I don't get any light or anything when I hit "on".
I checked literally every fuse in the under dash and under hood boxes. All are good. Is it likely it's the cruise switch?

On my 2009 F350 the cruise control won't stay on. The slightest bump and it turns off and I have to push the resume button. It's not the brake pedal/stop light as it will do it with me holding the pedal up. I'm guessing there is a vibration/crash sensor to turn off the cruise control in case of a wreck.

I've just bought 2001 f-250 crew cab and when I push the cruise control on the steering wheel it does nothing. Maybe a fuse or does my year have one of those master cylinder switches?

I have a 2003 f-250 5.4l and the cruise control quit. If you press the on and coast it will honk the horn so I am thinking switches on the steering wheel or the clockspring. I need to test those. Everything else works fine....

2000 F250 Super Duty cruise control not working. I looked through a lot of threads on this subject and cannot pin point my problem. Cruise control was working, had to slow down wile approaching a town, back on the highway and now it won't turn on.
Looked at the brake pressure switch, it was till good but was the old type but had the recall harness on it. Bought a new one and replaced it anyways. Still nothing. All my brake lights work, I also did the Cruise control diagnostic and it passes everything. No lights on my dash are on, speedometer works, horn works.
The only thing I did not check is the Vehicle speed sensor. Even though my speedometer works and my ABS light is not on, can this still be the problem? If so how do you test it? Do I just remove it and test continuity?
