Axle and transmission families.

§ 1037.232 Axle and transmission families.

(a) If you choose to perform axle testing as specified in § 1037.560 or transmission testing as specified in § 1037.565, use good engineering judgment to divide your product line into axle or transmission families that are expected to have similar hardware, noting that efficiencies can differ across the members of a family. Note that, while there is no certification for axle and transmission families under this part, vehicle manufacturers may rely on axle and transmission test data to certify their vehicles.
