In this video, we're going to show you how to remove and replace a gear style VSS, or vehicle speed sensor, also known as an output or transmission output speed sensor. If you like this video please click subscribe. We have a ton more videos on this and many other vehicles. If you ever need parts for your car you can follow the link down in the description over to 1AAuto.com. Here are the items you'll need for this repair.
We've put our vehicle on a lift to make it easier to film for you. This job can be easily done with a jack and jack stands. Locate your vehicle speed sensor, or transmission output speed sensor, which is located at the top of the transmission over the passenger side CV axle. Disconnect the electrical connector on the top of your speed sensor. Remove the 10 millimeter bolt on the driver's side of the sensor. We'll do this using the 10 millimeter socket and ratchet. Use a flat blade screwdriver to pry up and release the sensor from the transmission. You may have to grab the sensor with a pair of pliers and try to move it left and right to release it from the transmission because those O-rings can get baked in there from the heat and really get stuck in there. Remove the sensor from the transmission.
The way your speed sensor here works is this gear is driven by another gear inside of the transmission which tells us how fast that differential or the final drive is rotating. It lets us know the overall speed of the vehicle. These gears can wear out and have the plastic teeth wear off or the shaft can snap along with the electric pickups inside of the sensor breaking down, causing it not to read, which can cause issues with driveability and shifting. Fortunately, it's easy to change.
I've got some clean transmission fluid on my finger here. We'll lubricate that O-ring with it before we install it into the transmission. You could use another lubricant here, but ATF is ideal because we don't have to worry about this dripping in and contaminating our transmission fluid. Reinstall the sensor into the opening. Make sure you push it down there nice and evenly. Reinstall the 10 millimeter bolt, tighten it down with your 10 millimeter socket and ratchet. Reinstall the electrical connector onto the sensor and you're good to go.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
I'm going to remove the air box, just slightly out of the way, so that I can get to this connector better and undo it. Use a 10mm socket and ratchet. Loosen this up. There's a second one on the back side. Unplug this electrical connector here. Unplug this one here. This harness is actually connected to the air box, so can't pop it off, I'm just going to leave it here and move it to the side. Then loosen this clamp on the intake tube. Lift up the air box. Make sure those are fully released. Take our air filter out of here so it doesn't get damaged.
So, this harness here has a little push connector. I'm going to take these needle nose pliers and just push them together, and just pop it out. Put that aside. Put this aside, so it doesn't get damaged.
Move the NC sensor, which is located at the top of the transmission. There's an electrical connector here, and a single bolt holding to the transmission. And unplug the electrical connector by squeezing the plug and pulling it off of the sensor. Use a 12 mm socket and ratchet to remove it. Just got to work the sensor back and forth. Just kind of pushing it back and forth, it breaks the seal. Just going to work the sensor back and forth. Work it out over the O-ring. It's got a very tight seal, so it doesn't leak.
Here's the original sensor from our vehicle. Going to wipe off some of the oil on here, transmission fluid. See it's similar in design to the brand new one from 1AAuto.com. Same style connector. Same style single mounting hole. Comes with a new O-ring. This should fit in and work great.
Reinstall the sensor. Just reverse the removal. We have to work it into the opening the transmission. We just work it back and forth, and it sits down. Line up the bolt hole. Reinstall the bolt. Reconnect the electrical connector. Push it on until it clicks. Sensor is replaced.
Reinstall the lower air box. We've cleaned out all the debris that was in there. That's going to sit right back on the bracket. Get the bolts, and get them started. Tighten them down, socket and ratchet. Install the intake tube back into the box, just slides right over. Line it up on the radiator support. Just going to tighten those down, feel like I'm tight then I'll stop. Don't need to kill these, they're just holding plastic into the thin sheet metal.
Reinstall the air filter. Install the air box cover. It's got two tabs over here that need to go into these two hooks. Slide it over, and line up the little slot in the rubber with the plastic alignment tab. Make sure that the clamp is in the grooves. Tighten the screws holding in the air box. Then reconnect our electrical harness, clip it back into the spot on the air box were. Connect the mass air meter. And this little valve here, reconnect it.

So, this harness here has a little push connector. I'm going to take these needle nose pliers and just push them together. And just pop it out. Put that aside. Put this aside, so it doesn't get damaged. The NT Speed Sensor is located on this part of the transmission, just under the battery tray. Push in the connector to unlock it, and pull the connector off. Use a 12 millimeter socket and extension racket, just fits in here under the battery tray. Break it free. Put this bolt aside, so I don't lose it. And just work on, just kind of wiggle this back and forth. Pull the sensor right out.
Here's the original sensor from our vehicle. Going to wipe off some of the oil on here, transmission fluid. See, it's similar in design, the brand new one from 1aauto.com, same style connector, same style single mounting hole, comes in the new O ring. This should fit in and work great.
Install the new sensor, reverse of the way the old one came out, slide it right into the opening. Push it down. O ring has some tension to it. I'll push it in. Line up the bolt hole. Reinstall the bolt. I'm just going to get it threaded in with my fingers. Then we'll just tighten it down with a socket and ratchet. Wait til it gets tight. That's when I will stop. Reconnect electrical connector. It clicks on. It's locked into place, and the sensor is installed.
