On the drivers side. On the transmission, just above the cv axle.

    I do not have any sensors above the cv joint on my 2010 cobalt. Did the transmission change that much from 08 to 10?

SOURCE: transmission input speed sensor location

It is located on the front of the transmission. you will see 2 of them one on the left under small transmission lines it is the input then to the right behind the radiator overflow there is the other one. Easiest way to change them is with a 1" deep well socket

SOURCE: input/turbine speed sensor circuit

Your speed sensor, is located on top of the transaxle, near the starter. To access it, remove the battery, then remove the battery tray (4 10mm bolts). You will see wires coming from the lower oxygen sensor, and they snap into the bracket that holds the speed sensor in place. The actual speed sensor has a 2 wire clip on it, and is held in place by the bracket and a 10mm bolt.

SOURCE: Transmission Input Speed Sensor Replacement 1997 Plymouth Voyager

The first thing I needed to do was to identify my transmission. The 2000 Dodge Grand Caravan Sport (3.3 L) has the A604 transmission, as did any Caravan from 1989 to 2006. Might as well replace both sensor and will take less then 30 min from start to finish.

Vehicle's with A604 transmissions have chronic input and output speed sensor problems and also with the little wire connectors to those input and output speed sensors. The dealer offers a repair kit for these wires instead of buying a whole new wire harness. On most of these vehicles, If you have a code 41-44 you should check for weak battery voltage first. now the shop needs to check the wiring for poor grounds. I have seen that The transmission controller often goes bad causing these same codes, so be careful.

Parts/Tool List:
10mm socket (to remove top of air intake)
1" socket (to remove/tighten sensors)
standard screwdriver (to loosen hose clamps)
Vehicle Speed Sensor - INPUT
Vehicle Speed Sensor - OUTPUT

Removal/Installation:
The first step is to remove the airbox cover. This can be removed with a 10mm socket. Under the airbox cover is the actual airbox; remove the filter by unsnapping the clamps holding the lid in place. Maybe this is a good time to see if your filter needs to be replaced.

Once you've got the airbox cover and filter off, you should be able to see where the sensors are located on the transmission. On the left is the input sensor behind the Transmission Solenoid pack by the transmission dip stick tube , and on the right is the output sensor.

The input sensor is located just under two little hoses; remove the clamps and get those houses of the way. Make sure that you keep track of which hose goes on the left and which one goes on the right. To remove the sensor connector, there's a tab that lifts up, probably under the sensor. It lifts very easily, and the connector slides right off. If it's not coming right off, you haven't properly lifted the tab.

To remove the sensor, you need a 1" socket which should fit right over the terminal. The socket should also be large enough to clear the hose nipples. Note that with both of these sensors, the base is plastic. If you use anything other than a 1" socket, you'll rip the plastic to shreds and never be able to get the sensor off. USE the socket.

In most situation, the output sensor was covered in sludge, which may have been the source of the problem. Both the input and output sensors use some kind of magnetic receiving unit, and those magnets will pick up tiny metal shavings that are suspended in the transmission fluid. I suppose 10 years worth of buildup is enough to cause the sensor to throw bad signals. But maybe something on the inside caused the problem... so replacing it outright was the best decision.

Anyhow, after replacing the two sensors, the transmission problems 98% of the time will completely be resolved. No more weird cruise control issues, no more erratic speedometer, and no more 2-to-1 gear drops when coming to a stop. Problem solved. Good luck and merry xmass

The transmission is sealed. It is intended the fluidis to never need to be checked or changed. The dealer has a probe to check this function.

SOURCE: Key won't turn in 2008 Chevy Cobalt. Tried moving

now what it sounds like is the key has a sensor built in it the keys cost around 60.00$ but this is most likely what is wrong. the sensor is a security feature with the car if the light glows while trying to turn the car then this your problem :)

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

Location of transmission sencor??


The input an output speed sensors are located in the front of the transmission (the side facing the radiator). The input speed sensor is the one right below the rubber transmission cooler lines. the out put speed sensor looks exactly the same and is located more toward the drivers side of the transmission.

If you looking for a different sensor let me know. Thank you for using FixYa.com!

CANT FIND WHERE THE SPEED SENSOR IS NO MY 1995 OLDSMOBILE AURORA


hi , their is two different speed sensors on your vehicle one is the input speed sensor which is inside the transmission and the transmission will have to be removed to replace it the other one s the output speed sensor is located directly above the passenger side trans-axle shaft. your input sensor is the sensor which tells the transmission when to shift and the output speed sensor tells the speedometer what it should display and both those parts are fairly cheap they are around 15-25 dollars but just remember if your input speed sensor is bad it is gonna cost you a minimum of 1000 dollars to have a mechanic fix as the transmission needs to be removed hope this is what you needed

Input speed sensor


The input shaft speed sensor is located on the side of the transmission by where the engine "inputs" power to the transmission (via torque converter), thus rotating the input shaft.
The output speed sensor is located by where the axles attach to the transmission, and measures the speed that the transmission "outputs" to the axles (which make the wheels turn) and that data is also used for your speedometer reading.

My 91 dodge stealth is in limp mode how do i fix this transmission problem


Your car is in "limp"mode because the computer doesn't know what speed your doing,So it doesn't shift,
There are three possible reasons for this,
#1= input sensor faulty on transmission,
#2=output sensor faulty on transmission,
#3=speed sensor faulty on transmission,
you need to have the transmission codes read to know which one,Autozone checks codes for free.
