Derevjanik Lubrizol Corp. ABSTRACT The Aluminum Beaker Oxidation Test (ABOT) is a bench test required for official Ford MERCONB automatic transmission fluid (ATF) qualification. A continuous quality improvement approach identified inconsistent pump performance as the leading cause of test variability. A modified pump was developed to obtain consistent performance. The modified pump had a higher flow rate and a greater inlet suction than the original pump. An improved data acquisition and control system monitored and controlled the major test variables including pump operation. Our baseline fluid control limits decreased by 70% using the new ABOT system. From an experimental matrix, the new ABOT differentiated good, borderline and fail samples. The experimental data also show that a continuous 300 hour test sequence does not adversely affect test results. This paper documents the development of the modified pump and the results of baseline and matrix testing using the new ABOT system. LNTRODUCTION Ford designed the ABOT (Aluminum Beaker Oxidation Test) around 1965 to simulate the oxidative characteristics of the Mercomatic Transmission Oxidation Test (1). Since 1987, the ABOT has been the oxidation test required for Ford MERCONC3 automatic transmission fluid qu
