Ford Super Duty (1999-2016) :: 2015 F250 - Cold Tranny Noise / High Rev Sound When Accelerate
Aug 26, 2015
Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.

I'm going to cut right to the chase, when did ford stop having the diesel high idle when it is cold? I have a 2015 350 I bought last August and assumed it would high idle like previous power strokes. I even put a ts6 chip in my 97 just for high idle option to keep the motor warm when idling around our farm. I realize ford probably doesn't want trucks idling long because it kills mpg and isn't good for the emission system but to be honest I could really care less about mpg as long as it's decent and a high idle would keep emissions pushed through. Is there an option or anyway you can get the 6.7 liter to high idle?

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

I purchased an 1999 F250 Super Duty truck last Sept., it ran great all winter, now when I accelerate I notice a whining type noise (that's the only way I can describe it) it only does this during acceleration not @ idle, could this be a bad water pump? However there are no leaks or puddles of anything in my driveway.

Dealer says groaning noise at start up, when I let my foot off brake at a stand still is normal,worse if i turn steering wheel with brake on.

2 weeks ago, I purchased a 2015 F250 6.2 with 16K miles. Upon bringing her home, I noticed that there is a buzzing noise coming from the engine compartment after I shut down the motor which lasts approximately one minute (give or take). Since the truck is still under factory warranty, I figure I'll take it to the local dealership, but I'm wondering with the 6.2 has had the same issue and what the issue could possibly be.

I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.

So after this weekend's hurricane my 2011 f-250 started to making a noise when I accelerate. I don't know if water got in some where. But there's no MIL light coming on.

I have an 04 F250 6.0L and for the last month or so when I turn on my AC it makes a high screetching noise but only last for a little bit. Had a friend that works on cars on the side take a look at it one day and he said it was the AC cutch trying to engage. Does this sound like what it could be? Also if it is can it be changed out without having to remove the compressor? What all is involved in changing it out?

I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

So out of nowhere, my tranny started over heating. Got up to 210. It usually runs in the 140-150 range. I have the 6.0 cooler, and 7500 miles on the synthetic fluid. My cooler lines to the radiator were ice cold. I crimped my bypass and this seemed to fix it a little (I know this is a no no), I did the flow test before driving it and it passed. It seems to heat up the most at stop lights in gear. It drives fine, no slipping, no chattering. I also dropped the pan, had some stuff on the magnet, replaced the filter too. It doesn't seem to heat up as bad now, goes to about 190. I will install the new bypass tomorrow when it comes in from the ford dealer. Whats causing the heat? BTW truck has a 4" lift with 35's no other mods.

Heard a 2011 F250 gaser while driving in the morning just falls flat on its face, almost like its starving for fuel as well as it feels like the tranny is slipping too. What this could be? I am not sure if its electrical or what.

I have an intermittent problem with my 09 F250 Diesel. A few times now under hard acceleration I have had the trans seemingly get stuck in 3rd gear. The little service required wrench symbol showed up on info screen but after shutting off the engine no codes were present. A week or 2 later this happened again and I ran diagnostics through my Spartan tuner and got P0771 and P2704 for codes.
Again they cleared when I shut the engine off. Since this is an intermittent problem, only after hard acceleration, would it make sense to change tranny fluid, maybe do a tranny flush? Or am I off to the dealership for a rebuild?

Noise question. I have a 2011 super duty f250 xlt, and my question is I have a grinding noise that does not sound metallic and only shows up when its below freezing, only in drive and for about 50 yards.

I have a 1990 F250 with a 7.5 liter and an E4OD. It starting acting up a couple months ago. Tranny would seemingly go into neutral while on freeway. I figured trans was going out... After reading several threads I've decided to try changing the mlps first, got a new one at the dealer!!!. It is the updated one with the connector on the top. I'm currently waiting on a new pigtail from autozone (the original is in bad shape, wires frayed, insulation missing. Also I think when it started having issues we were having some serious rains, which may have caused this connect to get wet.
I believe a previous owner may have had the trans rebuilt at some point. The connect has 6 wires going in it and when I trace those wires back, two are spliced into one farther up the harness a bit. Looks like one is tied into a wire that goes to the solenoid harness. I'm hoping I can cut and splice the 6 wires into the new pigtail and be good.
For now, while I was under there I decided to pull the solenoid plug as instructed to make access to mlps plug easier... the lock is on the backside almost impossible to get to, I messed the plug up all the way around, but not fubarred. When I pulled the plug out, it was soaked in transmission fluid... Is that normal?

6.2L F250 truck is just shy of 60k runs good however on cold startup there's now a pretty loud ticking noise for a short period (30 seconds) until it warms up then it slowly goes away. Once its warmed up there isn't much of anything.
Did these have exhaust manifold gasket problems like the 5.4? Hoping that's it if not, any other common problems that would make that ticking noise and then go away quickly once the engine is warmed up.

I'm looking to buy a 08 f250. It has 70k miles on it. The guy is running a mini max tuner on it. I did notice on a cold start as soon as he hit the acceleration it had alot of black smoke. Is this normal? And is there anything I should b aware of when looking this truck over.

I've got a 2015 F250 with a 6.2 Liter with no compression on 3 cylinders. The dealer just diagnosed it and has not opened it up yet but the mechanic says it is probably a broken valve spring...that it is not uncommon in this engine.
My concern is not repairing the spring my concern is what a "free spinning" piston in 3 cylinders does to the life expectancy of the main and connecting bearings in this engine. I have rebuilt engines in the past and I have bought re-built from auto parts stores and from Jasper and I have never had any last more than 60-70K miles. It seems to me that even with very little mileage on the engine with three of eight pistons jumping around under no pressure that there could be considerable scarring of the bearings or bearing surfaces. I am no expert by any stretch but this is an engine in atruck that has less than 22K miles on it and I ain't real happy about opening it up let alone trusting for the next 280K miles that the bearings have more wear on them than they should have. It was only driven about 20 miles total like this but that is a lot of pressure on a highly tuned and pretty darn precision machine.
This is the newest vehicle I have owned since 1988 and I meant for it to be the last pickup I drive (I drive 'em til the wheels fall off) but I am not overly confident that even if this is a one off problem that it hasn't caused even more damage that won't show up for another 100K miles or so???

I have a 15 F250 CC SB 6.2 4x4 that is suffering from a driveline vibration. Had the shaft checked for balance and it was off. It's a little better now but still there. Checked all the angles and they're correct. Also came up with a curious observation that all CC SB 4x4's have a slip yoke driveshaft at the transfer case while all the other trucks have the fixed yoke. This appears to be my source of the vibration.

2011 f250 gas 4x4... I bought last year with 65k miles, now has 105k. sometimes when accelerating it slips for a second like a manual would if you jabbed the clutch while pulling. I had the 100k trans flush done. I noticed it a couple times before but more frequent recently. How concerned should i be?

I have a 1999 ford f250 with a 6.8 liter v 10 engine. At about 40mph the truck will start missing and lacks power to accelerate further. This problem is intermittent. Some days it runs great and others the miss appears. Well I scanned and the code reader said that I had a misfire on cylinder 7. I took a chance and replaced the COP and the boot for that cylinder . Ran great for a day and then the miss came back. Same code again. What else might cause this? Are plugs difficult to change in these engines?
