Ford Super Duty (1999-2016) :: 1990 F250 E4OD Tranny Would Seemingly Go Into Neutral While On Freeway
Apr 3, 2017
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?

2005 F-250, Diesel, 105K miles, all stock, fuel and oil filters changed in May, about 4000 miles ago.
three times in the last 4 days the truck has seemingly run out of fuel. Got a full tank about a week ago, at the same place I always go, so I doubt it is bad fuel. It ran thru a 1/4 tank with no problems.
4 days ago, it wouldn't start. It just didn't seem like it was getting fuel. It sat for several hours and then ran fine for about 15 minutes and then slowly died out. It wouldn't restart. It sat for 8 hours, and then started again, ran for about 15 minutes and I cut it off.
The next day, it started fine, I drove it 3 miles, cut it off, and an hour later it started but ran for only 10 -15 seconds and it slowly died out just like I was running out of fuel.
I started it this morning and it fired up right away. I let it idle in the driveway for 30 minutes, and it ran fine. I cut it off, went to start it 30 seconds later and it won't fire again.
The backyard mechanic I use for simple stuff wants to replace fuel filters and see what happens. BTW - twice when it wouldn't start, he hooked up his computer and it had no error codes. You can hear the fuel pump running when you turn the key on and the mechanic said he could feel the pump working when he put his hand on it.
Should I let him do that or is there something else we should be looking at?

I have a 2010 F250 extend cab 4x4. While traveling about 70 down the freeway I get a whistling noise. It is usually worse when the wind is blowing hard or behind a semi. Wind makes the noise louder so I assume the noise is coming from the air hitting something. Slow down to 50 and noise goes away. Do not think it is mechanical because when a gust hits the truck it is worse. Checked all the windows, windshield and rubber parts. Where I should look.

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?

I have a 2013 F250 with a 6.2 L. While driving the vehicle the exhaust sounds nice and throaty. When I put the truck in neutral and rev it, it's quiet, you can barely hear it. Is this normal?

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.

Driving up a slight hill unloaded yesterday at about 40mph constant pedal pressure the truck shifts into neutral...at least that's what it feels like. Revs go up and no power. When I take my foot off the pedal the transmission catches and drives fine. There is no bucking or hard shifting, just that slipping. What it could be? This problem arose suddenly....never had any problems prior. It is not an issue that has gotten worse over time...

I have a 2014 f250 with the 6.2 and just turned 13,800 miles. I tend to drive in tow haul a lot, while not towing because I like the shift pattern better and saves on brakes while stopping. Last night I slowed to a stop sign, came to complete stop. Went to take off slowly like always and the truck was like in neutral, looked down and the indicator showed 5th gear. Let off and watched it go to 1st and took off no problem. This all took only half a second or so, seemed fine after that. What might of happened?

97 f350 5.8L E4OD Transmission. This truck will not downshift when you come to a stop. You must manually shift it all the way through and then it does fine. What is causing this issue? It will kick down into passing gear. What is wrong?

My 1990 F-250 with the 460 overheats when driving in overdrive. Driving a hundred miles will turn the trans fluid brown and the transmission is very hot even though it drives just fine. If I drive it out of overdrive I have no problems at all.
It all works fine except the overheating in overdrive, no flashing on the overdrive light. The tans shop is not getting a code, they tell me they have to rebuild the tranny.

Yesterday wife left driveway and about a block away she phone truck "died". It actually starts and the engine is fine - shifting from park to reverse or any gear seems to have no effect. After tow home - i check and there are no codes (using ODBII scanner), the tranny fluid seems full and red. Looking carefully there is a slight rpm drop when idle into reverse or a gear other than neutral or park... but revving engine in any gear doesn't move the truck.
Is there anything else i should check before taking to a tranny shop? Its a 230k mile workhorse for the house but not critical if its down for a week or two. I have had it for 10 years and put the last 40k miles on it. Is there any diagnostic suggested given the symptoms?

I've got a 2003 F350 CCSB SRW V10 Auto 4X4 3.73 LS diff. The tranny doesn't always go into overdrive when I get about 40 or 50, even 60. I went down the freeway the other day at 65 in 3rd turning about 2500 rpms. Am I hurting anything here? One thing I have noticed is the overdrive light on the shifter does not work. Light doesn't come on. Leads me to believe that there is a frayed wire in the steering column. Could that cause the tranny to act funny? The cruise control works, so I'm thinking the speed sensor on the diff is ok, but I could be wrong.

2006 F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trans sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop diagnostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

2002 F250 5.4 Crew with limited-slip diff.
I put in about a quart of MERCON-compatible this weekend when the level was low. Found out that last tranny flush used MERCON V.
Now I have at least a quart of the MERCON-compatible in with the MERCON V fluid.
Should I not worry and just use MERCON V from now on, or will the two fluids have problems in my tranny?

I have a 2006 F250 Lariat CC FX4. I bought the truck with 68,000 miles about 3 months ago. This is my first 4WD and I'm wondering if I need shocks.
I know how to check on a car but this suspension is too stiff to push down a corner so how do you test? Or do you just go by the age? At freeway speeds when I hit a bump I get a bit of a shudder that makes me wonder if the axle is hopping.
If I were to replace them are the Rancho shocks OK for a replacement? I will spend very little time off road and mostly use this truck for boat towing and hope to buy a travel trailer down the road.
