Output Speed Sensor Location
Recieved a P0720 from the machine and need to replace the Output Low Speed Sensor. However I have the service manual and the Heynes Manual but can't make heads or tails of the location of it. Both the Haynes and the ServiceManual have the exact same picture. Any help would be appreciative.

RE: Output Speed Sensor Location
Well I purchased the Output Speed Sensor from AutoZone (Part Number SU394) but I think this is incorrect part. I need to replace the Output Speed Sensor for the tranny (Pulling from error code P0720). But I think that is the incorrect part. I can't find that part anywhere under the truck or on the tranny.

RE: Output Speed Sensor Location
hi there i am having the same error code on my truck. The check engine light came on the other day and the truck was acting weird so i had the code pulled today and it is p0720. the symptoms i have notcied are when im at a complete stop and the vec. is in gear (drive, reverse) the speedo reads twenty ish km. When im coming to a stop the spedo will drop down to zero but once i've reached a full stop it bounces back to twenty, when i start to accelerate from a stop the speedo instantly drops to zero and goes up as i increase speed, seems to be working properly. If I put the truck in park the speedo drops to zero but if i depress the bake pedle while in park it sits at about twenty again. The other symptom is if I have my foot on the brake and im at a stop and I shift into neutral i can hear a clicking noise (and kinda feal it in the pedle) it clicks about 10 times then stops, once i shift back into drive it does the same thing, about ten clicks. The truck also seems to be late shifting. I do not have abs in this truck. Any suggestions would be great, is there any way to acutaly test the output speed sensor? How about the entire circuit? The clicking noise makes me think possibly a solenoid if there is one in the circuit. thanks in advance -dan

Well the P0720 Error Speed Sensor is only $20 and it takes about 3 minutes to replace with a standard cresent wrench. Is that the only code that the computer is spitting out for you. Not sure if you have a Kragen near you but here is the piece that I fixed to fixed my P0720 error. http://www.partsamerica.com/ProductD...79&PTSet=A
That part is assuming that you have the same tranny as I do (46RE)
At one time I had a similar issue where my speedometer wouldn't register until 15-20 MPH and it turned out to be the vehicle speed sensor on top of the rear differential. It is about $45 and takes a 1/2 socket and about a 5 minutes to replace. However at that time, my check engine light was NOT on (my ABS light was).
I have ABS in my truck but here is the sensor for a NON-ABS truck.

Have you checked the fluid level in yout tranny? When was the last time you changed the fluid and filter?
