Ford Super Duty (1999-2016) :: 2005 F350 Will Not Downshift With Pedal Pressed To Floor At Medium Speeds
Apr 8, 2017
Recently my F350 has failed to downshift when the accelerator pedal is pressed to the floor to speed up in traffic. It will usually happen when traveling at speeds in the 30's-40's. It will shift quickly at slower speeds. I have a scan guage on it all the time and it is not throwing any codes.
The transmission has only been serviced by the dealer; last done about 24000 miles ago. No leaks or low fluids/no burned smells. Stock setup with no heavy towing use. Currently at 228000+ miles, this is the first issue with the transmission assuming I am looking at the right area for the cause.

I have a 2005 f250 super duty turbo diesel 6.0 automatic. The problem I'm having is, when I engage the tow/haul button the transmission doesn't down shift unless I feather the pedal. Also the engine will overheat at times. I've replaced the thermostat, but that's all so far.

2015 F-350 diesel purchased Sept 2104. When towing my 16,000 lb 5th wheel the 6 to 5 downshift seems to have gotten much harsher in the last few months. About 10,000 miles on the truck, much of it towing. Is this an indication of a developing problem?

I have a 2004 Ford f-250 super duty 6.0 turbo diesel. I noticed yesterday that it was making a jet sound when i pressed the pedal and got louder as i increased the speed. When you let go of the pedal it goes away. I have asked around and some say it could be the turbo...the diesel mechanic THINKS it could be the fan clutch. The truck doesn't overheat and if i punch it i don't think i sense any loss of performance. All I know is that it makes this sound like a plane taking off.

Had a No start issue.Turn the key and nothing. Could hear the relays click so knew it wasn't the ignition. Could jump the starter via the wire on the passenger fender so starter good. Replaced the clutch position switch last night. Still have no start but now when I press clutch I have a tow haul light come on dash.If I press it again it turns off. Truck doesn't have tow haul option installed. I hear a relay clicking under the dash too. This is a 2004 Superduty (F550). Replaced the ignition switch today and still same.

I'm having issue with my brake lights. Checked for voltage and nothing. Checked the fuses under the dash. Checked the brake pedal switch and have power going out when the pedal is pressed. Is there a relay or something somewhere else? 1999 f250 7.3 superduty....

I have a 06 f360 PSD 6 speed. On a road trip and the clutch pedal is getting very close to the floor. No Slippage but the longer I leave the pedal pressed the worse it gets. Are there any good descriptions how the clutch in this truck works?? Slave cyl??

I was driving, Iput the brakes on then suddenly I heard a loud bang and brake pedal went all the way to the floor. I knew there was something wrong with the brakes, parked went and checked the passenger side rear brake caliper was ripped off which made a hole through my rim and also ripped off the brake lines. I need to get the part but I don't know what its called. See the pictures....

The other day I got in my truck and started down the driveway when I realized I had no brakes, I slowly backed up and parked it. I haven't driven the truck for approx. 2 weeks and it seemed fine then. The master cylinder is full, there are no signs of leakage from wheel cylinders or lines. Today I unscrewed the left front zert and no fluid came out. My pedal goes all the way to the floor.... Whats going on, and if its a easy fix?

First, I am fortunate that I was only going 25 mph when some turned in front of me causing me to slam on the brakes. The pedal went to the floor, but did slow the truck enough to miss the jerk. Had I been on the highway, it would have been very bad.
Anyway, what I found is still hard for me to believe for two reasons. It find it hard to believe it failed, but more important that I am getting the last national inventory of 2 of the 3 lines in this picture (according to my Ford dealer).
The three lines are almost directly under the front end of the master cylinder between the block and frame. These are as I found them. The larger one goes to the rear feeding both rear brakes while the two smaller run to the front brakes. The spring looking part below is just a plastic protector. The line which failed goes to the front left.
I think anyone with a 2005 SuperDuty which uses the same or similar parts should take a very close look at the flex sections. The parts I have ordered are: 6C3Z-2B523-BA, 6C3Z-2263-BA, and 6C3Z-2264-BA (rear, right, and left).
How long a manufacture is required to maintain inventory? I thought 7 years, but someone suggested 17. I'm at 8 years, but I would have expected more than 1 each of the fronts to be available. Do they changed parts on the '06 or '07?
My 350 spent 2 winters in the Chicago area and has been resting in Florida since 2006. No work was done in this area, but the closest work was the main fuel pump (frame mounted) replaced 2 years ago, but that is almost 2 feet to the rear.

I have a clunking noise that I can feel directly under the floor board that definitely seems suspension related. It is getting progressively worse, it's not constant but it is magnified when hitting bumps, pulling out of driveways etc. I have jacked the truck up and tried to simulate the issue with no luck.

Pulled out of street this morning and as I was shifting into 3rd my clutch pedal went straight to the floor boards. I was able to keep it in 2nd gear and get it back to my driveway . The pedal will only go straight to floor or goes straight up too the bottom of dash board. It's spring loaded. Am I dealing with a linkage issue?. I had clutch as I pulled out of my driveway and stopped go at the stop sign. Plus I was able to drive it back too my house with the pedal on the floor boards. Where I should look first?

While in Tow/Haul with my 5th wheel when slowing down probably at 5 or 10 mph the last downshift is very hard and the brake pedal gets real soft until full stop. Afterwards the brake pedal is firm. Tow/Haul without the trailer is fine. It's an '06 F250 Supercrew 4x4.

My stock 2009 ford f250xl 4x4 with a 5.4 and 6 speed has been giving me a weird sound lately started about a month ago and only happens on a cold start situation meaning if it sits over night it will do the sound. the sound goes away after 3-5 min of warm up in my driveway, the sound happens when i push the clutch pedal to the floor. it has no pronounced abnormal sounds through out the rest of the day when its hot which perplexes me, check out the vid on my u tube site for a sound of it.

I have a 1999 f350 v10 stock truck. It has plenty of power when it's cold out or raining or I'm on backrooms or highways but if I drive through town on a hot day the transmission kicks bad I have changed the fluid and filter, it also seems to shift at a high rpm from 2nd to 3rd. Unless I you let off quick and go back on kinda like engaging a 2 speed rear end. Does it need a bigger trans cooler or is the trans shot

I don't know what's going on maybe some body can shed a little light on this. If you hold the brake pedal down for a long period of time you can feel the pedal slowly go to the floor. So no problem I'll change the master cylinder bleed everything brand new fluid. Don't drive it much we let the sister in law drive it we'll I jump back into it the other day to go to Home Depot and once again I notice it still does it. Could the hydra brake booster be bleeding by or what's else could be causing this it's driving me insane. I really can't imagine the hydra booster causing a problem but it's new to me. I was thinking about bleeding the brakes again thinking there maybe there's air but I have run 2 bottles of brake fluid through how much more??

1999 F-350 7.3 Dually 2wd Front End issues. I think I may have several things going on so here goes. Truck has about 130,000 miles on it . Bought it with 60,000 miles in 2009.
It's always worn the front tires weird but it's gotten a lot worse and it's happening in about 10-15 thousand miles now. It's wearing the tires on both sidewalls like under-inflation but I run 70 lbs in them. I've noticed for several years now that it makes a knocking sound and I feel it in the floorboard, shakes in the steering wheel when I turn to the left only in a corner at speed. (65-70) ...
Now it's started intermittently going into the death wobble at slow speeds like the caster is to negative on it. I'm sure it could use some shocks but I just rotated the tires and I felt no play anywhere. I know when we used to get that bumping in the floor board on older Fords it was a bad radius arm bushing but that couldn't be all of what's going on here. I've done searches on this and it has happened to others but I haven't found a resolution from any yet.

At low speeds, I notice a squeel sound in all four wheels. Ford tells me that it is due to the type of metallic pads they use and is essentially brake dust noise that warrants no repair.
Any after market pads that are good quality for towing heavy loads, yet aren't metallic in composition? For instance, are porcelin pads a good choice.

A bit annoying. 2008 F-350. When the truck is cold there is a creaking feeling I can feel through my foot. It usually lingers while the truck is warm but eventually goes away. It's in the actual pedal. This may be a stupid question but is there anything that can be lubed under there ?

my dads front drivers brake caliper was dragging so last Thursday he had the local Ford dealer install a new one WHY i don't know since i always work on everything of ours plus my friends Fords. Today he said he pushed the brake and it went to the floor then he let up and pushed it again and they worked?? I haven't looked into it yet but the dealer cant look until Friday morning so my dad asked me to do it today after work..... what should i check for? leaking brake line, maybe air in the system still?
