I too own a 2003 Ford Taurus that all of a sudden quit moving as if it were in neutral in late September 2010 with 146,000 miles. My Ford dealer immediately knew what the most likely cause was before servicing it. Their standard repair is to replace both the Torque Converter and the transmission fluid Pump Shaft, which is driven by the torque converter.
Either the shaft binds and then breaks, or the torque converted is defective. In my case it was definitely a defective torque converter, but I let them replace both components anyway. They convinced me they knew exactly what to do.
After circulating a flush chemical treatment to remove any particles that might adversely affect the operation of the valves in the transmission, followed by a 30 quart flush of transmission fluid and $1291 later, I was on the road again. I currently have 154,000 miles with no subsequent issues.
I wished Ford would have covered some of the cost, as my dealership admitted that this is a very common problem on the 2003 Taurus. Depending on where you happen to get stuck, it could be a safety issue.
In an unrelated incident only 3,000 miles in late December 2010, my Camshaft Synchronizer Shaft Assembly "chirped" so badly in the cold, that the engine almost stalled and set a Check Engine Light Code.
When they removed the shaft, it looked like a piece of varnished wood. That told me the 5W-20 Synthetic Blend specified by Ford was the wrong engine oil. I switched to Castrol Edge 5W-20 and the car runs better with a slight increase in mileage and no chirping.
I would recommend you use the full synthetic oil of your choice in your daughter's 2003 Taurus, and NEVER use that Syn-Blend stuff again.

The power door locks and the power mirrors stopped working. I check the fuse for the mirrors and it was blown. I replaced fuse and it blew out as soon as I put it in. What should I check for?

Hiya folks. Driving 600 miles back from vacation our '03 Taurus (3.0L) just decided to stop pulling with no warning, only a slight shudder before complete neutral. Park still holds, so i assume it's the usual cause that i've read about here (torque converter splines). The yellow tag on this car has "AEZ4 / 1F1P-7000-aa. I happen to have a known working tranny from a '01 Taurus with the same 3.0L. The yellow tag on the '01 reads AEZ0 / 1F1P-7000-aa. They both have a"1Z" also on the tag. My question is can i swap them over as is? Hoping i can drop the '01 tranny in my '03. Thanks.
#157 of 181 Heat Related transmission problem?
Jul 21, 2011 (11:20 am)
last year we purchased a 99 taurus with only 52,000 miles on it. We totally regret our decision but it is what it is at this point. Early this spring we noticed that sometimes the car would stall on us, because while the engine wanted to go, the transmission wouldn't. It was worse on hotter days and eventually last month, we had it totally rebuilt to the tune of $1800.00 (w/ new alternator) It drove fine (according to my husband) for about a month. Now we are in a heat wave and it's doing the same thing. The transmission loses all power and is stuck around 20 mph. It eventually kicks back in, or we turn it off and restart it. The rebuilt trans has a two year warranty on it but at this point, I'm wondering how well of a job the guy did! Does anyone know of any heat related 99 transmission problems? The car at this point has 65,000 miles on it .. new brakes, new struts, new alternator, new fuel pump, new tires, new battery, new transmission ... ugh .. what a waste of money.

Same problem. Car seems hesitates, slipping out of first gear when accelerating from a dead stop, especially when going left or up a steep grade.
Also, noticed a squeaking sound, and it has gotten worse lately. Vehicle has ~70k miles. Engine and pretty much everything else are in good shape, no indicator lights.
Trying to figure out what to do. Local shop gave it a test drive and pounded the hell out of the accelerator (likely making whatever it is worse) and going "see, it's slipping gears" when it wasn't. It only slips that first gear.
Transmission fluid is black, and was never replaced. Maybe past the time that can be done without doing damage.
Looking for an idea. I mean, yeah, one could replace the whole transmission, but I'm not sure its even possible to find a warrantied certified transmission for the vehicle at its age (and I'd want that warranty if I'm shelling out that much).
I don't think it needs all that. I'm trying to filter out experts versus thieves. The mechanic I trust says, "drives fine except that, but I don't know enough about transmissions to diagnose it." Well, at least he's honest.

We took our car to two other shops over the weekend, both claimed it sounded like the trans was gone again so we took it back to the trans specialist.
He called today after having the car for three days and is now certain that our catalytic converters are clogged? This frustrates me, as we specifically asked him to check the cat's the first time the car was there and they were "fine" That was a month ago, now they are bad?
He said he can do it for us for $500.00, when I told the price to another shop in town the guy told us the trans shop is probably cutting us a deal because he knew that he did wrong in the first place with the cats/trans ordeal but doesn't want to say so. Either way we don't have the 500.00 to put into it, after putting in 2,000.00 for a rebuilt trans/alternator.
This '99 taurus is costing us approx. 300.00 a month to maintain .. if only we could go back in time and pass it up.

sounds like that was a real honest tranmission shop selling a $125 new torque converter for $650 and then charging $200 labor to install it you got a real good deal
#161 of 181 Taurus Transmission
Aug 16, 2011 (10:48 am)
I have a problem with my transmission.
Car is 1995 Taurus with OD automatic and 3.8 engine
My daughter was driving on the freeway for about two hours when the car stopped going. Engine would rev up but tranny was slipping. She pulled over and a kind man helped her.
He check tranny oil level and put several quarts of fluid in before the level showed up on the dipstick. He told me It was leaking fluid where the pump seal would be. It had a huge puddle under the car when I got there. The car would move but slip real bad.
I got it home on a tow dolly and check the fluid and topped it off. Started the car and looked underneath and not a drop was leaking. ????
It would go in reverse with no slipping. In OD it feels like it is in 3rd gear, in drive feels like 2nd gear and when the gear lever is in L, it is in low gear.
car shifts OK if I manually move the lever thru the gears, but it will not downshift or upshift on its own when in OD.
Thanks in advance

I went to the dealer in Sept 2010 and they charged $180.00 for the New torque converter and $70.00 for the pump shaft and $20.00 for a special gasket. The rest was a bunch of labor which involved a lot of flushing with a solvent followed by 30 quarts of Transmission fluid.
I recently noticed a puddle of transmission fluid on the ground in early August. I got under my 2003 Taurus only to find the leak was coming from ABOVE the AX4N Transmission pan. I tracked it to the Transmission filler/dip-stick tube.
But I learned that it was caused by a clogged transmission air vent (coated steel) having a rubber check valve cap being stuck per the links below.
http://www.taurusclub.com/forum/82-maintenance-repair/128662-removing-old-atx-ve- - nt-won-t-budge.html
I followed the Technical Service Bulletin showed below to remove the straight press-fit vent with a 90 degree vent and 5/16" hose:
ERRATIC FLUID LEVEL READING ON TRANSAXLE
DIPSTICK - LEAKS - 4F50N,AX4N, AX4S
The reason I mentioned this was to ask, could this cheap vent valve being stuck open have caused last year's torque converter failure by introducing moisture into the transmission internals?

Not sure if this has already been posted, but my '97 Ford Taurus will not shift into reverse, 1st, 2nd or 3rd gears. It will go into neutral. My hubby drove it Monday to work. He stopped to get a drink at a gas station. When he got back into the car and started it again, would not go into gear. When we checked the fluid, there was plenty of it. What could this be?? I am new here and any and all responses are welcome!!!!!! Thanks!
