As zman17 said, it's on the driver side of the transmission near the back. My truck had the same code last summer and I replaced that sensor - new one was under $20 at NAPA. Make sure you have the new one handy before removing the old one because it starts barfing out tranny fluid as soon as you remove it. Very easy to change and gets rid of your P0720 code.

Just my .02. But the code is for a output speed sensor. NOT a vehicle speed sensor. Big difference. rear diff has a VSS on it(just like the ABS/speed sensors on the front wheels) . A output speed sensor picks up its signal on either the output of the trans and/or input of the t-case(4wd). You dont have a scanner available? Lots of tests can be done to ensure that the sensor is bad or not. The code is for the signal the computer gets from the sensor. DOES NOT mean the sensor is bad. I've fixed this issue(CEL) without changing the sensor, it's not always the problem. JD

I didn't mean too **** anyone off I was just pissed off about the truck. I apoliige to anyone i may have offenneded. Just had a bad day I guess. please forgive me. Anyway I put the old stock air cleaner on it I had a 14x3 and it did nothing I'm thinkink maybe the map sensor or something like that is going on to make it stall like that.
