Ford Transmission :: 1989 AOD Transmission Stuck In Overdrive

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!

Ford Transmission :: Clutch Chatter When Taking Off With The Wheels Turned - Diff Or Transfer Case?

My 2000 explorer has picked up a clutch chatter when taking off with the wheels turned. It is AWD, and has an 8.8" LS rear end with and 173k on the clock. Is there any good way to tell where the chatter is coming from? I know how to check the TC clutch, but it requires dropping one of the driveshafts.

I may try changing the rear diff lube, as I am sure it's never been done. They say "lube for life" but no fluid can last forever, I would think.

Also, on that note... a couple years ago I had a pinion seal leaking and the shop said it was 2 quarts low when they fixed it and said "rear diff damage has probably already occurred" on the ticket. While that is possible i suppose, would think i would have major problems right away as the diff only holds 2.5 qts (IIRC). Least wise, that was probably 50k miles ago when I had it fixed.

More than likely, the mechanic was an idiot and it was only .5 qts low, as i'm 99% sure that they left the pinion nut loose when he did the job. (had a terrible vibration that mysteriously went away when i brought it back for them to find out what is going on .. they said they didn't do anything, but it was fixed when i got it back ... they don't get my business anymore)

Anyway ... would i be able to feel that clutch chatter with one rear wheel in the air and the trans in neutral? Assuming the worst case scenario, and the TC clutch is going out, how big of a deal is it? Can i get another 20K-30K out of it before it gives up the ghost?

Ford - F250 :: 1997 - Transmission Goes Out Of Overdrive?

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???

Ford - E350 :: 1991 - Goes In And Out Of Overdrive - Burns Up The 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.

Ford Transmission :: Rev Without Engaging If Overdrive Is On - Metal Sludge In Pan

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.

Ford Transmission :: Stumbles Or Shudders For A Second Or Two In Overdrive Intermittently

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.

Ford Excursion :: 2000 - Transmission Slipping In Overdrive

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.

Ford Aerostar :: 1993 - Transmission Dropping Out Of Overdrive

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?

Ford Transmission :: 1994 Ranger Keeps Shifting In And Out Of Overdrive

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?

Ford Transmission :: 1998 F150 4.6 4x4 Won't Shift Into 3rd Or Overdrive

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.

Ford Transmission :: 1990 E4OD Goes On Overdrive Mostly Only When Go Up A Hill

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.

Ford - Explorer :: Automatic Transmission - Rough Shift Into Overdrive

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.

Ford Escape / Hybrid :: Transmission Shudder When Downshifted From Overdrive

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?

Ford Transmission :: E4OD - 1990 F250 Overheats In Overdrive

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.

Ford Aerostar :: 1995 - Automatic Transmission Won't Shift Into Overdrive

My 95 ford Aerostar 3.0 automatic trans wont shift into overdrive, here's what happened. a small hose on the side of the transmission came off, this must have popped off when I was stepping on the gas with the brake on in drive and reverse. It took 2 months to find the hose off, during those 2 months I had to shift the van manually, you had to get high RPMS before it would shift.

About 2 weeks before I found the problem I notice the van would not kick into overdrive. When I finally found the issue and reconnected the hose the trans shifted fine but still would not kick into overdrive though. Is there another vacuum hose that goes to the main vacuum housing? or an adjustment on the linkage area? This has been like this for about 6 months now and I can go on a highway..
