Ford Transmission :: Rev Without Engaging If Overdrive Is On - Metal Sludge In Pan
Aug 27, 2013
I need to decide what to do with my transmission. I just acquired a 2007 F150 Supercrew 2WD 4.6L truck with 184k miles. While in Drive the automatic transmission (4R75E) runs ok thru 2nd gear and then; if O/D is on it will rev without engaging and if O/D is off it will just stay in 2nd gear.
I was hoping the problem was a broken retainer clip, as are so many others. So I removed the pan, and the valve body. All of the retainer clips seem to be fine, but, there is a lot of metal sludge on the magnet of the pan. See pic.
Should I buy a complete rebuild kit and take the tranny out of the truck? Is it just a problem with the valve body? I need to get the truck going so I can get to work. I am uneducated in the transmission department.

For the past few months, pretty consistently, whenever I engage the clutch from full stop into first gear (it does it when starting in second gear too; and reverse) there is a pretty obnoxious and loud screeching noise that I would liken to a subway/train braking or just metal on metal grinding situation. When I took the car in to Douglas for an oil change and APR Stg 1 flash, they told me it's just the brakes being cold, etc. After driving the car some more, I really doubt that it's the brakes and I can reproduce this regularly by slowly releasing the clutch and get the noise usually just before the gear engages.
That car has just over 16K on the clock and has never been abused. The clutch pedal feels fine and there is no issue shifting into any of the gears other than the noise. No mods other than the APR Stage 1.

I have a 2003 Kia Sedona EX with 103k miles on it. It is currently in the shop (KIA Dealership) and I'm being told that I have metal flakes in my oil and excessive sludge in my oil passages. This is causing my oil pressure to come in at 15 PSI instead of the specified 93 PSI. My mechanic has recommended a new engine.
I have only had the vehicle for 9 months and have done regular oil changes in that time.
Is there any hope of cleaning out the sludge? If yes, what do you recommend?Can I do successive short-mile oil changes?Can I use SeaFoam or some other product to clear it?Did I just happen to buy a car that hadn't been taken care of very well and now I really do need a new engine?
I've already replaced in the last 6 months of the 9 months I've had it:
Tires (Less than 10k miles on them)
Front & Rear brakes (whole thing)
Water Pump/Timing Belt/Serpentine/etc
Catalytic Converters - both fronts and the rear (just last week!!!)

5 Speed Manual in an 85 740 GLE Diesel. The overdrive does not engage until the car has been running 15 minutes or so. What causes this?

My '89 Ford Crown Victoria Country Squire is a 5.0L with the AOD transmission. Yesterday, I slowed from 40 mph to 25 mph to turn on my street. As I drove up the street's slight incline I noticed the acceleration was sluggish as if the transmission had not downshifted from 4th to 3rd. When I stopped to back into my driveway, the engine shuddered and stalled as if it was hooked to a manual transmission and I had released the clutch with the shifter in an upper gear. My wife had to push the car into the driveway (she is a Minnesota farm girl ).
Now the engine starts normally with the gear selector in Neutral. It shudders and stalls the moment I try to put it in any gear or Park. The engine will not start in Park, but once again, balks as if I was trying to start a manual transmission equipped car without depressing the clutch or taking it out of gear.
The transmission and engine had been working perfectly before the above sudden problems. My guess is that the transmission is somehow stuck in overdrive.
Is there any way to knock it out of 4th gear? Why would the engine start in Neutral but not Park? It is the original AOD transmission with over 230K miles on it, but this car has at least nine lives and I am hoping this is another serious problem that turns out to be not so serious!

I and a friend both have 1997 ford F250 Diesel pickups and both at about 140,000 miles have had problems with the transmission going out of overdrive and changing gears at higher than usual rpms. The overdrive light blinks and if the pickup has a day or two it will reset the computer and function normally. Any fix easier than a new transmission???

We recently purchased a 1991 Minnie Winnie (Winnebago) which rests on a 1990 Ford E350 chassis. It only has 58k miles. While driving on the freeway or highway, the Overdrive starts to go in and out; downshifting and upshifting willy nilly. It has a manual button for turning off the Overdrive and when I do this, it stops jerking and drives smooth. But, of course, this effects the gas mileage significantly. I took the Minnie to a garage recommended by the company I purchased the Minnie from. They replaced the manual Overdrive switch and replaced the transmission with a rebuilt Ford transmission.
We got it back and it was okay for one trip but by the second trip, it was doing the same thing again. I took it back to the garage and since it was under warranty, they put in a new rebuilt transmission, another new Overdrive switch, a new fuel sensor and checked the wiring but it still had the same problem. So they sent the onboard computer board to Ford who rebuilt it. The guys at the garage thought for sure this would resolve the problem. It didn't. They have exhausted their ideas as to what is causing this problem. We love the Minnie Winnie and other than this problem it is in beautiful condition.

I have a 2006 F-150 SuperCrew King Ranch. The 4R75E automatic transmission has some sort of fault. In overdrive...intermittently...it stumbles or shudders for a second or two. By feathering the throttle...it calms down. If the overdrive is cancelled, the shifting from 1 to 3 is fine. The fluids and filter have been changed.

I have an unmodified 2000 Excursion 7.3. with 239000 miles on it. My transmission started to slip in overdrive. I could turn off the OD and it would run fine. I was in upper Wisconsin headed home to Georgia and figured the cold had something to do with it. Drove sixty mile with OD off turned it back on shifted fine and drove 750 mile to Paducah, KY stopped to eat and it started down the road and it slipped again.
Drove 45 miles stopped added 8 oz of tranny fluid and it drove fine back to a friends house and after I dropped him off and headed home it started again. The tranny is serviced every year, new filter, drained torque converter. I use Amsoil Synthetic ATF. I have used the truck to tow a 10000lbs trailer over 65000 miles. I was not towing when this occurred. What is going on? I guess what I am asking is my tranny about to become toast or am I looking at something that can be fixed easily.

My 2010 F-150 with 170,000 miles - 6R80 Transmission is starting to chatter while shifting into overdrive. It lasts about two seconds and then all is well. I'm sure it will get worse.

I have a 1993 Aerostar 3.0L, automatic. The transmission has started dropping out of overdrive into drive while at speed. It's very inconsistent as sometimes it will drive without incident and sometimes it will barely go into overdrive and then drop back out and remain in drive for an extend period of time. I changed the fluid/filter/gasket thinking it was just overdue for changing but no luck. The fluid level is fine, perhaps even a little high. Fluid looks clean on the stick, so I don't think it was a lack of draining enough fluid. The problem seems to be more pronounced when warmed up.
Also when cold, I've had an issue with it stalling while taking off from a stop. I wouldn't necessarily relate the two problems, but someone mentioned they thought they might both be a symptom of a slipping torque converter or something. But the stalling issue seems to go away when it's warmed up.
Also had an issue with the van not wanting to start when damp. But I attributed this to water getting on the coil or plugs or something. What I could try before taking it to a shop and risking getting taken?

My 1994 Ranger keeps shifting in and out of overdrive. It will go into OD easily, but it keeps downshifting, then shifting back up constantly. If I go up hill, if will downshift and stay in drive, but on a flat stretch, it wont stay in OD. It works fine when its cold, but after it warms up, then the shift problem begins. What do I do?

I have a 1998 F150 with auto lock 4x4 and a automatic transmission. The problem I am having is after setting for about a week I drove it and 1st to second shift normally but when the RMP's/MPH hits time ti shift to third I get RMP increase and no third. I have shifted it manually 1 then 2 and into drive same result RMP's increase just like it is in neutral.
Miles on trans is about 120K have been serviced about 10K ago with no poor color or smell. Mechanic said transmission and filter looked good no metal or junk in oil. I drive down the road and it shifts from first into second then about 35-40 it hits what should be third but nothing free RPM's. I let it slow down to below 35-30 second kicks back in and away we go again until it's ready to shift into third.
I have been told possible speed sensor problem, possible other sensor problems looking for leads on where to look and what items to check. Just had Shop Mechanic drive it and he was baffled for everything looks good that he checked such as oil, and how it drove until it tries to shift into third. No over drive light flashing or anything and no engine codes showing at all everything clean in memory.

I have a 1990 class C motorhome with a 460ci engine an a E4OD transmission, It shift pretty smooth, but it goes on overdrive mostly only when I go up a hill, and down shift as soon as I reach the top when it should be the opposite. I bright it to a tranny shop, they change fluid and filter and make road test on a plane road and find no problem.
The way I see it is that it shift 1-2-3 then I hit the OD button and it goes on 4, then, if I'm going up a little or asking for more power it upshift another gear(5th ) and when I coming back on a plane road it downshift to the 4th gear until I need more power. It doesn't look normal to me.

I was wondering should I find metal in my pan after a rebuild on my AOD? It's been about 4 months since the rebuild and i took it in to have the fluid changed at another shop. Now the unit is doing fine but I did let the shop that did the rebuild know what was found.

I just installed a rebuild 4R100 transmission in my 2001 4x4 Excursion with the 7.3. I'm having trouble getting it to engage into gear. As I shift it into gear it sounds as if it wants to engage but doesn't. I have checked the fluid level and it at a normal range. I'm wondering if I didn't put enough fluid in the converter would that cause the problem.

I've got a 1982 Courier 2.0 2wd 5speed pickup and it's been passed down through my family and has sat for quite a while so I started tinkering with it in my spare time.
I began with the motor and got it to run after 15 years of sitting around but am having issues with the transmission. When I first got it running a while back i had it in gear and when I let out on the clutch it lunged forward a little and stalled. I have since then towed it a short distance across my yard (in neutral of course), but now it seems like it isn't doing anything while it's in gear.
While its running I can put it in gear (even without the clutch) it doesn't grind jump or anything. Everything feels like it's okay as in going into all the gears. I was wondering if this is possibly clutch related or if it's the trans itself. Or maybe some electrical thing related. I haven't taken anything apart yet in hopes that it's something simple. I was curious if it might be low on fluid and maybe that would cause it not to engage properly?

My '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.

My 2002 Explorer LTD with 155K miles on it is in terrific shape except for a worsening rough shift into overdrive (automatic transmission) and a clunk which occurs with increasing frequency when I shift into reverse. I would love to keep the car but don't want to spend the money for a new or rebuilt transmission. There is no access for owner approach to transmission fluid - I have already looked in the manual. I would need to take the truck to a garage as I cannot do repairs myself.

My wife and I have a 2002 Escape and basically love it, however, at my last oil change, at 26,000 miles, I told the service manager about a shudder I was getting from the transmission when it down-shifted from overdrive. He suggested a transmission fluid change since I was in the range that Ford recommends.
That totally corrected the problem for almost 4000 miles, however, the shudder is slowly starting to come back at 30000 miles.
Just yesterday, I took it to my Ford dealer for inspection, oil change and it's 30000 mile check up and I mentioned this problem to the service manager. He suggested that I make an appointment.
The problem is that right now, it is happening so infrequently, if they took it for a test drive, it might happen right away, or not at all, but I know it will get worse as time goes on.
Question. Should I wait until the problem gets worse, and second, what might be the cause?
