2006 jeep grand cherokee input speed sensor were is it on gearbox

Odometer or ABS?

On the transmission, drivers side. In front of the main harness. It is the input speed sensor. small plug.

the code means.
to do the tests listed in the fsm. book, not guess.
we do the tests, and find out if the cause in in the transmission
the TCM or the TCM sensors or the solenoid drivers or solenoids
or the actual transmission internals.
why guess? why ask folks to guess. who are blind.?
ever seen the book, and read , the chapter on A/t trans on car tests?

i guessed drive line... so....

the book hints at....
- Faulty Input Speed Sensor 2 ,.is dead.
- Input Speed Sensor harness is open or shorted
- Input Speed Sensor circuit poor electrical connection

The Input Speed Sensor 2 is one of the two hall effect speed sensors that are used by the Transmission Control Module (TCM) to calculate the transmissions turbine speed. Since the turbine speed could not be measured directly, two of the drive elements are measured. Two input speed sensors are required because both elements are not active in all gears.

Hi Daniel: This site has a great pic that should help you: https://www.google.com/search?q=auto+diagrams,+2006+jeep+grand+cherokee+,+input+speed+sensor&biw=1174&bih=493&tbm=isch&imgil=NutTbKwbbJCkDM%253A%253B49jz1kwMg6_erM%253Bhttp%25253A%25252F%25252Fwww.jeepforum.com%25252Fforum%25252Ff310%25252Freplacing-transmission-speed-sensors-287793%25252F&source=iu&pf=m&fir=NutTbKwbbJCkDM%253A%252C49jz1kwMg6_erM%252C_&usg=__q-m30iBaQDcje8kxFpIgBu322Bg%3D&ved=0CCkQyjc&ei=f3NTVZPOD4HOsAXiz4DICA#imgrc=NutTbKwbbJCkDM%253A%3B49jz1kwMg6_erM%3Bhttp%253A%252F%252Fwww.wjjeeps.com%252Fservice%252Ftrans_speed_sensor.jpg%3Bhttp%253A%252F%252Fwww.jeepforum.com%252Fforum%252Ff310%252Freplacing-transmission-speed-sensors-287793%252F%3B576%3B476

This is your input speed sensor, there are 2... one for input one for output.
Photo attached showing location on gearbox/transfer box

there several speed sensors 1 on every wheel for abs called wheel speed sensor and in transfer case 4wd or awd call output shaft speed sensor or vehicle speed sensor and input shaft speed sensor which can be a computer generated signal from crankshaft sensor and output shaft speed sensor this is to determine torque converter lock up.

Try this.

yes it will if the trans controller does not see and input speed it will not shift out of first gear.

Throttle position sensor

Hi Ghecham,
I have done some research and it sounds more like the torque convertor may be the problem,As the speed sensor would affect the whole speed range and not just the range under 3500rpm's
I will continue to check on other possible causes while you are having the other parts replaced.

Thanks again
