Parts & Accessories Spare parts New sport traction control unit in its box. A very rare part for Corolla models 20-21-22-23-24-25-26. This part is only available in the mid-option and full-option trims. I don't need it, so I'm selling it. You can install it on the standard trim by going to a workshop to remove the old one and install this one, and it will work for you.
