Form A (refer to 2.3) is required for testing to be started on gear lubricants pursuing DEXRON Gear Oil approval. 3.2 Mechanical Requirements. Test procedures shall be conducted as specified

12、, with no deviation, unless express written authorization is obtained from the General Motors Automatic Transmission Fluid (ATF) and Gear Oil Committee. Test parts are to be used as received. Replacement or modification of any part shall be made only if directed in this specification or to replace d

13、amaged parts. The laboratory must target to the mean of the specified test conditions. 3.3 Physical Requirements. Fluids qualified under this specification shall conform to SAE J306 and to the test methods and requirements as listed in Appendix A, Table A1. 3.4 Approved Additive Chemistries. 3.4.1 F

14、luids meeting this specification shall be manufactured using additive chemistries listed in Table A2, approved DEXRON Gear Oil Additive Chemistry Combinations. 3.5 Requirements for New Additive Chemistry Combinations. 3.5.1 Successful completion of a complete DEXRON Gear Oil Qualification Program (A

15、ppendix A, Table A1). 3.5.2 Successful completion of a complete DEXRON Gear Oil Qualification Program (Appendix A, Table A1) using the following fluid blends: 3.5.2.1 Seventy-Five (75%) Candidate, 25% Reference Fluid. 3.5.2.2 Fifty (50%) Candidate, 50% Reference Fluid. 3.5.2.3 Twenty-Five (25%) Cand
