I've noticed a lot of aftermarket transmission companies painting their products purple. Must be some sort of a fad. I have seen ATS transmissions and their torque converters are painted purple, BTS uses a torque converter that is painted purple but their trans is not. A few other companies are also using purple paint on their clutches and torque converters. Some companies on e-bay are even marketing their products as "high performance purple". I just do not understand how gullible some consumers can be if they think purple paint makes a difference.
