Acura - MDX :: 2004 - Transmission Started Hesitating When Shifting Into Overdrive
I have an 04 MDX it has over 100k on it, and about the time it was approaching that milestone, the transmission started "hesitating" when shifting into overdrive.... then it began to try to shift into overdrive way to early driving in town.... and it felt like we were riding across rumble strips every time it would do this.....We have found out.... that if we do not move the transmission selector lever into the overdrive position, but leave it in D4 [thus manually avoiding the overdrive] it does just fine....
We just suffer in the gas mileage dept., but it does not feel like the transmission is going to fall out while riding in town....My question is; is there a way to disconnect or disable the overdrive so that no matter what gear someone puts it in, it will not try to shift into overdrive by itself.When I am driving it; it is not an issue, I remember to not use overdrive every time; but when the wife or the children drive, they sometimes forget, and I am afraid it is going to do real damage beyond low gas mileage......
I have heard that this is a common problem with this vehicle, and that replacing the transmission is a very short-lived solution, as the problem is design related and will eventually happen again.
Cherokee :: 95 Jeep Transmission Not Shifting Into Overdrive
Transmission not shifting into overdrive, running high on RPM's, BUT not all the time. Sometimes it does, sometimes it doesn't. Could it be an electrical Module that is causing the transmission not to shift into high gear? Had the transmission checked out several times without going inside it and they say it is fine???

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?

, 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.

I purchased my car almost two years ago. I drive a lot for work, and my car now has 74000 kilometers on it.
So far its gone thru 3 CV Axle Joints on the drivers side, a radio unit, clutch bearing, fork, and fulcrum, and now there's something wore out in the rear suspension (squeaking and snapping).
The transmission in mine has also started to grind when shifting like the syncros are wearing out. Motor knocks when it's cold, sounds like the top end goes dry of oil when sitting overnight and takes awhile to get any.
Ford Excursion :: 2000 V10 2WD - Transmission Started Shifting Hard Between First And Second
I have a 2000 V10 2WD Excursion with 104,000 miles. Last week it started shifting hard between first and second, but only when I am between 1500-2k RPMs. If I rev the engine higher, it shifts smooth. I checked the fluid and it is fine. I rarely tow anything except my little trailer to the dump every few months. I have a few questions:
1. Should I drop the pan and change the tranny filter?
2. Should/Can I check the rear diff fluid? (haven't noticed any leaks)
3. Could an inline flush and fill work?
4. I saw a post about a speed sensor in the rear diff. Could this be the issue?
Ford 6.0L Power Stroke Diesel :: Transmission Started Shifting Badly - Codes P0976 And P0755
Recently picked up a 2004 Ex 6.0L. Drove great for a bit, then it started shift badly, then finally the Tow/Haul light came on. The original codes were P0976 and P0755.
P0755 being shift solenoid B, and the P0976 being SSB Control Circuit low. I replaced Solenoid B and that code went away.
P0976 stayed with no change in how the truck drives. Replaced the internal harness today, and again no change.
At this point I'm at a loss. I'm wondering if it's something between the PCM and the transmission?
Lumina :: 92 Chevy 3.1 Crank But No Start - Car Started To Stall Sputter
This car started to stall sputter. I replaced the ignition module and it worked for while then nothing at all but still cranks. I checked all of the fuses and every thing was working. What I have found and i think this was the whole problem. The wiring harness that goes from the ignition module to the crank sensor, the wires were twisted and frayed and most likely grounding out on the frame and making the computer to shut down. So far after replacing the wires it started right up. Have not had a chance to take it for a test run to re learn the computer because my brake line busted.

Trying to figure out if she jumped timing or maybe PCM went out. Car started dying going up hills then stalled out on level road. Found coil pack for #3 and #6 bad and replaced it. Other's arced ok so I left them alone. Didn't work for starting it so I checked the fuel pressure and got 37psi with key on and engine off.What would cause it not to even try to hit? Considering maybe it's jumped timing or the PCM is going out.

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 7.3L Power Stroke (1999-2003) :: No Overdrive - Hard Shifting From 3rd To 4th
So I have a 2000 F-250 7.3 and my over drive won't work. I also had hard shifting from 3rd to 4th and 3 gear wouldn't try to shift until about 2500 RPMs which is high. I replaced solenoid pack and no change. I have rebuilt the tranny and found that OD snap ring had came off I put upgraded spiral ring on. When I went on a test drive I found out nothing had changed except shifted smoother. So I changed valve and accumulated body still no change. Truck is throwing 4 codes:
P0733 Gear 3 incorrect ratio
P0750 Shift Soleniod a fault
P0783 3-4 shift error
P0541 intake air heater a circuit low
Could it be PCM??
Ford - Explorer :: 1995 - Bang Shifting When Overdrive Off Light On Intermittently?
I have a 1995 Explorer 4x4, and starting last month i have been having an intermittent problem with bang shifting, the only time the bang shifting occurs is when the overdrive off light flashes, the only time the O/D Off light flashes is after driving the interstate or driving around town on hot days, after a few days or a few weeks the light turns off and its shift normal and no bang shifting, but i have a new problem now, the O/D Light off started flashing last night after driving the interstate and I noticed on my way home that it wont shift, it hit 4000rpm and i had to tap the break and accelerate again to make it shift, I went to AAMCO and they wont give me the codes the only thing they said is they want to do a soft parts rebuild, and something about hte gear ratio being off, i dont have the money to spend for a new trans or have one rebuilt, i would like to fix this myself.

View 5 RepliesCamry :: 2003 Tranny Started Slipping In And Out Of Overdrive
Okay so I have a 2003 Toyota Camry with 358, 000 miles. I replaced the transmission in 2010 with a gently used one that only had 100, 000 in it. Out had been running great until today when it started slipping in and out of overdrive. I had to turn the o/d off just to drive home and not get it over fifty. Now I don't know if I need to change the filter and fluid or just take it to a mechanic. I read on another site not to change the fluid and filter at such high mileage b/c the clutch and guys might rely on the friction of the gunk in the fluid and that new smooth fluid might keep it from running right.

I have a 2001 3/4 pickup. Sometimes the over drive light flashes. When it flashes it shifts really hard and sometimes it won't shift into 4th until I mash the overdrive button. Sometimes the light doesn't flash at all and it doesn't have any trouble shifting at all. Is it a solenoid? Or wiring issues?
View 6 RepliesChevrolet - Lumina :: Loud / Buzzy Whine That Changes Pitch With Engine RPM / Transmission Speed
I have a '99 Chevy Lumina 3100 V6 with 54k miles. There is a loud, high-pitch buzzy whine that changes pitch with engine RPM/transmission speed. The whining noise is only evident while the car is accelerating (forward or reverse), and above 5 mph. I removed the serpentine belt and drove it briefly (500 feet) - the noise is still there without the belt. I figure it's safe to assume it's not the power steering pump, alternator, H20 pump, idler or belt tensioner. The transmission has had regular service, and shifts smoothly in all gears (fluid is clean and level is full). There is only a slight raspy "scraping" noise in park or neutral, which becomes almost undetectable when shifting to drive or reverse with the brake still applied.
View 1 RepliesChevrolet - Lumina :: 1995 - Transmission Malfunction - High RPMS But Barely Moving?
I woke up and drove to a stop sign. When I tried to pull away the transmission raced like crazy, HIGH RPMS! But was barely moving. After about 8-15 mph it would finally catch 2nd gear. I check fluids frequently, and topped it off a few weeks ago, and when I finally got where I was able to stop, I looked and there was no fluid registering. So I put 2 quarts in to fill.... Then started the car and it would not go into any gear completely. I'd just feel a small thump, when I shifted. It will actually drop into gear after a while going straight, but it's stil revving HIGH and it won't completely go into reverse. Weirdest thing, the "Anti-Lock" light came on while all this was happening...
