HI,

I am sorry that you have not been helped yet. I just came online and saw your question

The P0705 is for the gearshift position sensor. The P0863 is a communication fault between the ecm and tcm. This may be in the CAN network, or a faulty ecm. You really need a VIDA scan tool to diagnose this
