Transmission Sensor Location.

Hello, seeking help. Does anyone know the precise location of the transmission sensors or have a diagram of it? Even a video would be helpful. This would be for a 2015 Chevy Spark 1LT Automatic CVT transmission (input shaft speed sensor and output shaft speed sensor)

Thanks in advance!

Hi,

Based on my manual, there is one output speed sensor and two input speed sensors (primary and secondary).

I attached the directions below, which show locations, for replacing all three of them. I'm not sure which you are replacing or if all three are even needed.

Let me know if this helps or if you have questions.

Take care,

Joe

Is this for a 2015 Chevy spark transmission (CVT) (American model)?

I ask because according to google, it only has 1 input speed sensor. But I asked chat gpt for specifics of what you mentioned, and it does in fact say it has 2 input sensors.

I live in America (U.S.A) so I’m looking for the American model diagram.

Thanks in advance!

For a 2015 Chevy spark transmission the CVT transmission has 3 speed sensors. Please check the wiring diagrams below for confirmation. Check out the images (below). Please let us know what happens.
