Fifteen fluid formulations were evaluated in 30 city buses operated in normal service for more than 2,000,000 mi; it was determined that fluids fail because of frictional deterioration and oxidation; two fluids were found to be satisfactory for more than 40,000 mi; one additional fluid was satisfactory for more than 30,000 mi, remaining 12 fluids failed in less than 20,000 mi; it is concluded that with properly formulated fluids, drain intervals in city bus automatic transmissions can be as great as 40,000 mi; however, drain intervals should be established by evaluating fluids in bus service for which they are intended; analysis of fluid samples taken during test can aid in establishing optimum drain interval.
