I should elaberate a little more on what ATRA does. They host at least one seminar every year in every chapter area for the new transmissions that are coming out,they work with the new car manufacters to solve
problems that occur in the new transmission designs. They come up with updates and modifications(technical service bulletins) to help transmissions last longer.They offer a nation wide warranty,repair books,tech/trouble shooting help line,and thet also host my web site for my shop. You can't go wrong by being a member.
