More than likely we still have an issue with the wheel speed sensors or overall system.

We need to start with getting the ABS codes and here is a video that will help with this.

Then we need to follow the testing for these codes but more than likely what is happening is a wheel speed is not being communicated properly and that is affecting the shifting of the unit as it uses wheel speed sensors to determine shifting.

This could be another speed sensor so here is a guide that will help with testing this sensor:

Let's run through this info and we can go from there. Thanks
