There are to speed sensors in the Taurus AX4N or AX4S transmission. One is called a TSS or Turbine shaft speed sensor, located on the body of the transmission cose to the driver's side, and the other is called either a VSS, vehicle speed sensor or an OSS Output Shaft Speed sensor (both are synonomous names), and it is located on the passenger's side, down behind the engine on the top of the output shaft housing of the transmission. The PCM uses information from both sensors as well as other inputs like MLP(manual lever position) sensor, which is the PRNDL position sensor, calculated engine load(using throttle position and Mass air flow information to calculate), engine temperature, and input air temperature to make deccisions about how to shift the transmission. The Speedometer uses the signal from the VSS alone to determine and display vehicle speed. IT would seem likely that if you have a non-operational speedometer, poor transmission shift performance, and an inoperative cruise control, that the VSS is your culprit. Keep in mind though, that anything that prevents the VSS from spinning could also be your problem. THere is a VSS drive gear in the transmision, that is driven by another internal gear. Both those gears are plastic, and they do break sometimes. The probem is that the primary gear in that chain of gears cannot be replaced uness the entire transmission is disassembed. Let's hope that isn't your problem.
my transmission is not shifting on my 2005 Ford Taurus what could be the problem
Had the same problem off and on in my 1999 Taurus. The speedometer needs to be replaced. The problem is in the speedometer and not the transmission like I was initially led to believe. My mechanic said it wasn't that big of a repair.Coincidentally, the vehicle speed sensor feeds information to both the speedometer and the transmission....See "Related Questions" below for more
On Taurus 2003 and on Ford windstar it's located on top of the transmission, close to the shifting lever. It's covered with a small rubber cap that has inside ribs to allow air flow.
Speedometer quit working, car wont shiftI drove a 1993 Ford Taurus. It had transmission controlled shifting. In my situation, there was a very small $5.00 piece(plastic, of course) inside the tranny that controlled the shifting which needed to be replaced. I actually had it replaced at the dealer and cost me around $160.00. Sorry I couldn't help more but hope this gives you a direction, William
In the 1996-1999 Generation 3 Ford Taurus/Mercury Sable, there are several modules that are utilized in transmission control. The PCM, or "Powertrain Control Module" is responsible for all engine and transmission functions. This is the computer that manages all data to and from the engine and transmission. The Transmission Range Sensor (TRS, Range Module, NSS, Neutral Safety Switch, among other names), determines which gear the user has selected and tells the PCM what to do as a result. The VSS, or "Vehicle Speed Sensor" displays the speed on the speedometer but is also responsible for transmission performance. And on SHO model Tauruses, the ABS Wheel Sensors are instead used to display speedometer information, as well as control the transmissions shifting habits.
It is possible. Replace any broken mount, and this will eliminate the possibility.
check for a failed vacuum modulator or a vacuum leak to the vacuum modulator. It sounds like you are shifting on the governor or engine management unit.
yes it will fit...thay are all the axod trannys and any Taurus transmission will fit in any Taurus there is.
No, it does not. It's all electronic.
Either that, or the speedometer cable went bad.
MIGHT NEED A NEW SPEED SENSOR I posted the original question. I paid to have the symptoms diagnosed. It was actually a worn plastic gear set on the end of the speed sensor / speedometer cable and the mating gear in the transmission. The one inside the transmission requires tear-down of entire transmission... bad news.
inside the transmission.
where is the transmission speed sensor located on a 2005 ford taurus
The transmission fluid for the 2000-2004 Taurus is MERCON V.
Yes. They should both have the AX4S transmission.
No. 2000 Taurus and Sable are the only interchange.
No. The speed sensor is located on the transmission, and is what drives the speedometer cable, which drives the speedo head. The speedo head is another name for the the speedometer, which is the display gauge that you see while sitting in the car.
It could be a problem with the speedometer assy, since the two are actually one unit. It could also be a speed sensor which is located in the transmission housing on the the right side output drive axle housing.
You mean a 1992 Taurus SHO... yes all the MTX transmissions are the same from 1989 to 1995. the regular Ford Taurus does not have a standard transmission.
How much transmission fluid does a 2001 ford Taurus need
That's your CHECK TRANSAXLE ( transmission ) warning light . It's a gear with an explanation mark inside of it . Your transmission shifting may be limited , if the light stays on take it in for service
The vehicle speed sensor is the #1 suspect - it feeds critical data to both the speedometer and the transmission. See "Related Questions" below for more, including picture links, about the VSS
How many quarts of transmission fluid does a 2004 Taurus 3.0 OHV require when draining transmission and replacing filter
The transmission vent on a 2001 Ford Taurus is found on the engine. It is on the driver's side of the engine.
There is no drain plug on this transmission.
