Hey guys so a few months ago I remember changing the output speed sensor that’s directly on top of the trans. I don’t remember what codes it threw us. Now just today it quit moving in higher gears and wouldn’t leave first. I went out there with my scanner and two codes pop up. 585-2 and 673-2. 1 and 2 trans output speed sensors. Where is the second one at? They are both reading differently to on the status side of cat et. PER00544
Are you talking about the speed sensor on top of the converter housing.? The one that screws in and adjusts with a locknut. That's the transmission input speed sensor. It's the only one out of a total of five speed sensors that is accessible from outside. There are two intermediate and two output speed sensors. The transmission output speed sensors #37 are located together side by side inside the bevel gear goup. If the signal from both sensors failed at the same toime it's likely to be a wiring problem.
I bought the speed sensor that goes on top of the trans. It’s the only one I was able to find at the moment. Is there a part number for that and the harness? I’m not at my computer
I don’t know if they both failed at the same time or one after the order
How do you access the location of the bevel gear?
Start by removing the transmission and bevel gear assembly. that's why you have to be doubly sure there is a sensor failure and not a wiring fault. This is also the reason why there are two intermediate and two output speed sensors, for redundancy in case one of them fails.
You cannot access the transmission at all once it is installed in the machine. Was the sensor you bought 318-1178.? Did it look like this.? If that's it then you replaced the covnerter output/transmission input (same thing) speed sensor.
See where these troubleshooting procedures get you.
Turns out it’s the harness that’s causing all the trouble. There’s exposed wires in the rubber
I thought it was unlikely for both sensors to go bad at the same time.
Ya I tried to temporarily fix the wiring to the speed sensor but when I barely touched it it crumbled and fell apart.
