On page 34486, beginning in the first column, Section 1037.565 is corrected to read as follows: 1037.565 Transmission efficiency test. This section describes a procedure for mapping transmission efficiency through a determination of transmission power loss. (a) You may establish transmission power loss maps based on testing any number of transmission configurations within a transmission family as specified in § 1037.232. You may share data across any configurations within the family, as long as you test the transmission configuration with the lowest efficiency from the transmission family. Alternatively, you may ask us to approve analytically derived power loss maps for untested configurations within the same transmission family (see § 1037.235(h)). (b) Prepare a transmission for testing as follows: (1) Select a transmission with less than 500 hours of operation before testing. (2) Mount the transmission to the dynamometer such that the geared shaft in the transmission is aligned with the input shaft from the dynamometer. (3) Add transm…
