From concept through production of the 5th generation Camaro, GM engineers in both Australia and Detroit were in almost daily contact with Hurst engineers for guidance and design support. Stout Tremec TR-6060 and little brother, Aisin Warner AY6, transmissions were sent thousands of miles across the Pacific for testing and evaluation in conjunction with prototype shifters. Secretive track and laboratory testing including GM’s brutal endurance tests were run to ensure that this Hurst Shifter was the best.
