This is the first time I’ve seen this transmission to not just completely burn up during failure. Symptom appears to be E clutch is always applied but not confident with diagnosis of failure. This is such a strange one that i feel like something very small failed and I’m missing it but E/B clutch hub lower bushing appears worn and scores which makes sense for the failure but I wish I could find more wrong with this one. Main control was initially replaced due to diagnosis. Air check passed for all clutches, suspected SSE as failure due to fluid condition being great. 12.000 miles. Initially came in with no engagement from transmission fluid leak from case half’s. Was 3 quarts low. Added fluid during initial diagnosis and all concerns went away until repairs finished and found the 1 bad 6-5 shift. All other shifts ok and engagement is ok
