You still need a floor shifter with this unit, it is just for 1-4 shift control.

This will generate a code on OBD2 vehicles.

Consider adding the Selector Switch Kit for choosing TCM or manual control and controlling TC lock up manually.

Be aware that the Selector Switch Kit switches may not be available locally. Check you local parts supplier.
