Where are the speed sensors on a jeep?
There are two speed sensors on your jeep’s transmission. There is an input speed sensor and an output speed sensor. The input speed sensor tells the computer what speed is the engine in relation to the road speed. The output speed sensor tells the computer the speed of the tail shaft in relation to the road speed.
How does the N2 sensor work in a jeep?
With the vehicle moving forward or reverse, N2 speed sensor reading will be greater than zero in all gears. Whenever the K1 clutch is applied (2nd, 3rd, and 4th) N2 will be equal to N3. There is no speed sensor internal to the transmission that directly measures input shaft speed.
What is the name of the transmission speed sensor?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
Where are the input and output sensors located?
The engine speed is fed to the TCM via can bus thus providing impeller speed. There is no speed sensor internal to the transmission that directly measures output shaft speed. ABS wheel sensors provide output shaft speed. K1 clutch (N3 speed sensor) will show no rotation whenever the B1 Brake is applied.
Where are the speed sensors located on a jeep?
Signals from the speed sensors, N2 and N3, (6, 8) are recorded in the transmission control module (TCM), together with the wheel and engine speeds and other information, and are processed into an input signal for electronic control. Speed sensor N2 (6) records the speed of the front planetary rear annulus assembly (10).

Is there an input shaft or transmission sensor?
Whenever the K1 clutch is applied (2nd, 3rd, and 4th) N2 will be equal to N3. There is no speed sensor internal to the transmission that directly measures input shaft speed. However, when K1 is applied N2 equals input shaft/turbine speed. The engine speed is fed to the TCM via can bus thus providing impeller speed.
