Perfect fit and part for my Sonata
My 2008 Hyundai Sonata was dragging through the gears periodically and kept getting errors codes for transmission or speed sensors. The simple approach was to replace the sensors since it was a significantly less expense. After install the car ran beautifully and still does 10K later. Price, service and fast shipping make 1AAuto a great DIY partner.

Not quite right
I bought these as a set and only 1 was able to clip to the connectors for my car properly. I compared the sensor that has the straight up connector with my stock one and the sensors made just too long to clip properly into the connector. I will have to take a few CM off the front of it so the connector clips in properly. The sensors work fine, but the need to retro fit one was a tad bothersome.

Exact Replacement
These items fit perfectly; I used a little transmission fluid on the O-rings and they went right into place and worked immediately as expected.

Got me out of a tough situation!
I just paid rent plus bills, got groceries and filled the tank when my car decided to stop passing 20 mph. I went to auto shops and mechanics and they wanted to charge me 3-4 times the amount I spent here at 1aauto.com. Thank you lots!!

Car part
I received my parts on the exact date i was told to expect them. I paid less for the 2 parts than my local auto parts store wanted for just one. I like that i saved money and also got the parts in a timely manner.

Alex P May 30, 2017

Richard M June 2, 2017
Is the out put sensor on the right or left side?
Bobbie C July 25, 2017
If memory serves correct the Output is on the right and the input is on the left. But I would always replace the pair because it is easy to do, but more important they need to work in tandem and if one goes the other may not be far behind. Just like head lights, replace in pairs.
Daniel G July 25, 2017
Output Would be on your left side.
