Hi, my fiancé’s vehicle listed above just started having problems where it won’t change gears at all, even manually from second to third and the speedometer doesn’t move off of 0. There are no lights on and I had the car scanned and all that came up was an ABS code that was unrelated.

Hi,

Chances are the vehicle output speed sensor has failed. The sensor is on the side of the transmission. If you look at pic 1, it shows location.

First, make sure the connector hasn't been damaged or has come loose. If it appears okay, without testing further, that is my first suspect.

By the way, what code was found because that can all tie together.

Here are directions for replacing the sensor. Pic 2 correlates with these directions. Please let me know what code was found for the ABS before you replace the sensor.

2. Disconnect the output shaft (countershaft) speed sensor connector, and remove the output shaft (countershaft) speed sensor (A).
3. Install the new O-ring (B) on the new output shaft (countershaft) speed sensor and apply clean ATF to the O-ring, then install the output shaft (countershaft) speed sensor in the transmission housing.
4. Check the connector for rust, dirt, or oil, then, Connect the connector securely.
5. Install the splash shield.

Hi Joe, thanks for your help. I really appreciate it. I honestly don’t know the code. The mechanic only said it was unrelated to the issue she’s having. Your answer was also his initial suggestion as to the problem. I will take it to him tomorrow and have him put the sensor on. Fingers crossed and prayers that it solves the problem. Thank you again.

You are very welcome. And honestly, the ABS issue can be related. If the vehicle has stability control, everything ties together.

If you get the chance, let me know if it takes care of the issue for you.

Take care,
Joe

Hey Joe, just wanted to reach back out to you and tell you that we replaced both the input and output sensors. They were both looking worn out and chewed up and that seemed to have cured the problem completely. Thank you for all of your help. I really appreciate it. My fiancé is a happy lady again, haha.

Hey Joe, the car was working fine until this afternoon and now it’s doing the exact same thing again. Won’t change from 2nd to 3rd and speedometer won’t work at all. Any more ideas?

Hi,

Move the wiring around on the sensors you replaced. Chances are there is a bad connection or a broken wire. When you installed the new sensors, it was likely making connection.

Let me know.

I was going to ask if you thought this might be a wiring issue since it was working fine after installation. When you say move the wires around, do you mean wiggle them? I’m not a mechanic by any means, haha. But I really want to get this right and get her back on the road.

Hi,

Yes, if you wiggle them around at the sensors and it starts working again, we know it is a wire near the sensor. Also, you can remove the plug on the sensors and inspect them as well. Make sure there are no pins pushed in or corrosion. Plus, make sure they are clipping together tightly.

Let me know what you find.
