I have a 98 GC, 4.0 auto. The check engine light came on ant the code
is P0720, output shaft speed sensor circuit. I got part # 1-04800879
(the sensor). Can somebody who has the factory shop manual scan me the
troubleshooting/repair steps for this code.

The light has been on for a long time, but the JEEP was running fine.
All of a sudden, it stopped shifting gears, stays in 1st, so it is now
time to fix. I am going to change the sensor, but if I can get the
directions from here, I want to go over the whole circuit.

Thanks
John in Vegas

Bill sent a link that shows there are 2 speed sensors on the transmission.
I'd be concerned about now that I was getting ready to replace the correct
one.

Thanks Bill.
Jeff, Im not too concerned that I got the right one because the code reading
says its the output sensor. When I bought the sensor, the dealer gave me a
copy of the manual that explained the troubleshooting procedure for the whole
circuit, but of course I cant find it. I guess I will crawl under it tonight
and change it and hope the fault is in the sensor itself.

Thanks guys.
