Ford Aerostar :: 1997 - Auto Transmission Starting To Slip A Lot In Overdrive
Jun 8, 2011
Have 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 ?

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 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..

I bought it for cheap. not shure what tranny is in it. So when you you put it in od it will take off and shift fine all the way to od. getting going and drive it a few miles and it will slip out of od into to neutral. I can put it in drive and it does fine. I did lose all forward gears earlier tonight though. First time it did this. OD is the only gear it slips out of. it willl re engage below 40 mph. But I usually just shift to drive and go on.

I got this code and symptoms of 1-2 hard shift and no torque converter lockup. No flashing overdrive light on shifter. If I switch off engine all shifts are smooth until I pass 45mph. I would feel the TCC lockup. This doesn't happen the as i come to a stop I get a harsh 2-1 shift. Key off restart then shifts smoothly up and down provided I dont exceed the TCC lockup speed. This leads me to the TCC solenoid I think. Fluid has been changed regularly.
Had to drive 300 miles to get home. Only for the plate trans cooler the fluid would have overheated as on inclines on cruise control the engine would rev to 3k to keep the speed at 70mph and I could see the fluid temp increasing. Fuel consumption was very bad almost a full tank (with no ac). Doing some research there is talk about valve gasket blowout Epc solenoids etc, though these were for Rangers and Explorers, no real mention of Aerostar.

2010 STX with 4 speed (4r75E)... Yesterday morning when I was almost at work(20 minute drive) I went to accelerate from a stop sign and my truck acted like it was in neutral. Once the rpm's dropped to just above idle speed the transmission caught and I was able to accelerate as normal. I guess I didn't think much of it until I was coming home from work, again about 20 minutes of driving, when I was accelerating while turning left from a stop sign. Halfway through the turn my rpm's shot up to about 5000 and it was acting as if I were in neutral again. Just as before, when the rpms dropped to just above idle, the transmission reengaged and everything was normal.
I decided to take my wife's van to Walmart and grabbed a bottle of lucas oil "transmission fix". I figured it might buy me a little time before I am able to get it to a shop for diagnosis. I used a suction pump to remove approx. 24 oz. of tranny fluid through the dipstick tube. I then added the lucas oil "tranny fix" (24 oz. bottle). I inspected the fluid that I removed. It looks pretty dirty. I would say that it was a nontransparent brown color with a slight red tint. when poured onto a paper towel it still looked brown. It didn't smell burnt at all. I checked the fluid level twice before I added the lucas oil, and twice after. Both times the fluid level was at the full mark (fluid at normal operating temp, with vehicle in park after shifting through all gears).
Fast forward to today and I was able to drive from my current house to my new house(being built) which was about 10 minutes away. I had no issues at all with the transmission. after being at the new house for about an hour and a half I came back home with no issues. about 30 minutes after returning home I headed back out again to run some errands. About 15 minutes into the drive my transmission slipped again as I was making a right turn into the barber's shop parking lot. after about an hour at the barber shop I headed for home again. As before everything was fine for about the first 15 minutes until I tried to make a right turn after sitting at a red light. the transmission slipped as described before, but it did it twice this time in the same turn. Nothing happened after that within the last 5 minutes of driving home.
The slipping only seems to happen when accelerating from a dead stop or from an extremely slow speed(under 5 mph). At highway speeds the transmission down shifts and upshifts just like it always has. My truck has 78,800 miles on it and has never shown any previous signs of transmission issues other than a leaky dipstick tube that I replaced about 3 years ago.
My father had a 94 Taurus that had similar symptoms in the past and it ended up needing new clutch disks and was rebuilt. I'm hoping for that rather than a new or reman'd tranny!

Auto/transmission will not shift to overdrive. Is there a relay between the o/d switch and the solenoid? Is it alright to drive on the freeway?.1988 Volvo 240 DL.

My passat transmission is really starting to slip now. I have found a used transmission at a reputable salvage yard with 84,000 on it and its the same trans code and was told it shifted fine before they pulled it. I was just wanting to know what seals i should replace in the new transmission if any. I presume that with it being at a salvage yard all the fluid was drained from it so another question I have is how much transmission fluid should i buy when i do the swap not sure if 5 quarts is enough.

I have a new to me 2000 F250 7.3 diesel with automatic. Truck has 185K miles and tranny is starting to slip occasionally. Do these trucks come with a OEM tranny cooler or do I need to add or upgrade the OEM one. Someone also told that there is something called "bulletproofing" the tranny on these trucks. BTW, what would be a reasonable cost to have a two wheel drive auto tranny done on my truck?

Why does the automatic transmission stay in 3rd gear and not shift into overdrive until it gets warmed up? It is so annoying. This is the only car that has ever done this. Even the camry I don't think does this. Especially the fact that the rpms stay above 1k rpm until the engine is warmed up.

Tranny just started slipping a couple of weeks ago, only occasionally. Seems to be between 2nd and 3rd. any chance a fluid change will work? I don't have have the money right now for a new or rebuilt and I am far from mechanically inclined to do the work myself. 2000 F150 62K org Miles....

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???

I just bought a 98 f150 about a month ago from someone. The guy i bought it from said the tranny had been rebuilt about 4 months prior and i have the invoice proving it. I have lately noticed a hard shift from first to second gear, all other gears shift perfectly, but on my way from work toady the tranny seemed to slightly slip out of gear(in other words the rpms didn't shoot up, just loss of power) when accelerating from a stop light, and then it seemed to catch and started shifting ok. my question is given these symptoms is it possible that i can make this tranny last a little while longer or is it about to quit? any possible causes?

I 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.

My 97 AWD Aerostar bumps in and out of gear on very hot days. I've had the transmission fluid and filter changed. That repair worked, but it still shifts hard when very hot. I tow a boat. I always push the shifter button in to deactivate the OD when towing. I talked to friends who recommended an auxiliary transmission cooler. I looked on the van where one might be installed. I have a factory transmission cooler (oem factory installed).
The cooler is in front of the radiator. I don't see any room to add an additional cooler. The van has 145,000 miles. The van runs and shifts fine most of the time. The problem has happened only on very hot days. What I can do to prevent transmission problems. I've read that the AWD 1997s use a five speed transmission. 1997 was the first and last year the five speed automatic was installed in the AWD Aerostar.

, 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.
