Just got the results of oil analysis on Allison 2000 tranny oil. All was within normal limits except lead which was slightly abnormal. normal was <50, my reading was 58. This unit is new to me and this is the first sample for me after aprox 10K miles. Plan on shortening the next sample interval, and re-test. Analysis company indicated lead may come from clutches.
Anyone experianced this type of abnormalty?
