input and out put speed sensors tell the TCM and the ECM the difference between engine rpms and transmission input roms so that the correct gear ratio can be selected
A speedo sensor reads the out put shaft (drive line ) shaft and refers to road speed for speed and odometer readings and to calculate the fuel consumption rate
it is possible that you have replaced the wrong sensor
Talk with an accredited transmission specialist shop and have the problem diagnosed
Speedometer sensor measures axle(driveshaft) speed for your speedometer gauge.
Input speed sensor measures the speed of the input shaft of the transmission.
The output speed sensor measures the output shaft, the ECM compares these two signals to determine the amount of clutch slippage and adjusts parameters accordingly for optimal operation.
Ok the output speed sensor and the vehicle speed sensor are not the same sensor.The output speed sensor will be on the tailshaft housing of the transmission or to the rear of the transmission case if it is a 45rfe(5 speed auto).The vehicle speed sensor is in the top of rear differential housing.Be sure and douse the sensor with wd40 before you try to remove.Dry oring will cause sensor to stick and break and that can be a headache.Good Luck!
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
Its a rear speed sensor on top of your diff case its around 30 bucks if you do it yourself only one stud/nut, the 99 durango does not have a speedo cable.
It could easily just be a sensor, but if you don't know much about transmissions, you are best served to take it to a transmission shop and let them fix it. Now days, transmissions are very hard to work on yourself.
It is either your output speed sensor in the transmission, or if you have rear anti lock, the rear wheel speed sensor. Check both for metal contamination.
ok first replace the wheel speed sensor on top of the rear axle. if that does not work replace the vss on the transmission. vss vehicle speed sensor good luck
