I have a 2013 Honda Civic LX and after every light in the dash lit up, my car started having troubles shifting, etc. I got a code that the auto parts guy said indicated a bad speed sensor in my transmission. Read posts that led me to believe once I got the air filter assembly out, it would be waving at me, but no luck. Here's a pic of what I'm looking at... am I at least warm?
Seriously, appreciate any direction...

What is the specific trouble code?

 

Sorry, can't recall, just that it was the speed sensor. Saw a different post, think for this year, might have to access it from the bottom of the car?

 

There are different types of speed sensors. Without the code, it is just guessing.
