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???
View 5 RepliesMy 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.
I recently purchased an 02 F250 v10 4x4 with 150k from a local auto auction. The transmission, for lack of a better term, will "grunt" when going into third and in and out of overdrive. It doesn't seem to slip at all and the fluid looks slightly discolored, but it does not smell burnt. No Torque Converter whine either. A friend of mine who has owned 10+ SDs for his business said I may need to replace the TCM. Not too sure about that, because other than the strange noise, the truck seems to shift normally.
View 5 RepliesHave a 1997 Ford Aerostar van 4.0 L v-6 RWD 119,754 miles. Auto Transmission starting to slip alot in overdrive. Fluid and filter changes at 86,119miles. Have a Haynes Repair manual that only cover vehicles to 1996... Talks about the transmissions A4LD 4-Speed that uses electronic controls integrated into the on-board EEC-IV system.. Rather that covers my 1997 I don't know. Fluid looks very clean on dipstick. Crawled under van.... On side of transmission #P97GT7006BBR 750Nn. Took to a national brand Transmission chain.... Said trans overdrive wearing out. Anything else I can check or am i getting ripped off ?

View 3 RepliesI have a 98 f150 4.6 v8. when i start driving and i hit about 40 my truck doesn't want to shift, i have to take my foot off the gas, let it shift then apply the gas again. if i don't it shifts real hard or the RPM's go real high. and then every so often my overdrive off light blinks. it shifts in and out of overdrive ok though.
View 2 Replies, My 1997 Buick Lesabre transmission slips at random when I shift into overdrive. I have my mechanics look at the transmission and have them drive the car to recreate the problem and what do you know the car doesn't do it. I made a post about this problem a while back and it wasn't the A/C that was the problem. I do not drive fast in the car and I checked the Transmission dipstick and the fluid is still red and at the full mark. I brought my car to Auto zone to check the codes but all i get is a loose gas cap.
View 14 RepliesMy '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!
The tranny is on a 1997 f250 psd 222K miles it has acceleration shudder and o.d shudder. Tranny is getting to 250 degrees Fahrenheit and stays right about there but does not cool when it is park and idling.
View 2 RepliesMy 1997 F250 Heavy duty shifts very hard and sometimes feel like it slips out of gear (i press the gas pedal to the floor and speedometer rises very slow and truck doesn't move like it should.
View 14 RepliesI have a new to me 98 F250LD with the 4.6/4R70W. I have maintained this truck fro my FIL as best as I could get him to spend (neglected). Filter and fluid replace with Mercon VI last year due to 2-3 shift slip.
He gave me the truck after it would not climb a hill, just hit stall speed and would not move up a steep hill, as I understand it. I put Seafoam trans tune in hoping it would free up sticky solenoids or valves in the VB.
I finally got it registered in my name and drove it to work and back today. After about 25 miles highway driving it shudders pretty bad trying to climb a hill at low speed.
It seems to me that at this low speed, torque converter lockup should not even be a possibility. I do not have COP, but rather a single coil pack. I replaced the wires and plugs for Dad a few years ago, but some shady shop later told him that I didn't replace the left rear (to make an upsale I suppose). Not sure what they may have done in there.
I have scanned with my ELM 327 and Droid using Torque Pro, and the only Fault is EGR flow.
I have a 1997 F250 that I am fixing up. The issue is this... The dash lights now flicker off when I place the transmission in Drive position. I can slightly move the slack in the gear selector and the lights come back on. When the transmission is in Park, the dash lights work correctly. Not sure why there is some type of switch to control the dash lights buried within the steering column?
View 2 RepliesWe 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 95 f150 5.0 with a 4r70w Trans. What to check now no overdrive Trans shifts and drives great but no od the od off light on shifter is lit up and just never goes into overdrive solenoids have been replaced and new shift lever and button where do I go from here is not throwing any codes...
View 7 RepliesI 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.
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.
View 6 RepliesI 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.
View 7 RepliesI 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?
View 2 RepliesI 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.
