Hello,

This code can get triggered due to a bad pressure sensor which is located on the valve body of the transmission. It will require partial disassembly of the transmission.
This can also be due to the wiring issue for the sensor.

I have attached the troubleshooting guide for the code P0870 below.
This can help you determine what the issue is.

Let me know of any questions.
Thank you.
