Allison codes
Hello, I have a FORD CARGO CF7000 with an Allison MD3060p Automatic transmission. I have had a problem, I think the driver did something wrong in the speed control. The truck started to roll slowly, the control was in MODE on, this caused it to start buzzing and not pick up the speeds. the oil was correct. In any case, the filters and the oil have been changed and it has not improved, the codes that appear are 55-17 and code 25-11.
We are thinking of lowering the transmission, changing the clutch plate, a filter that is internal and putting in the new oil. Can someone help me to see what else can be done so that it takes the changes and works well? I would appreciate any guidance , I am a bit worried about the buzz ( noise - comes and goes ).
55-17 ( C3 clutch is the oncoming clutch in a shift and the C3 pressure switch did not close at the end of the shift.) .
25-11 ( Speed Sensor )
The transmission is at ALLISON MD3060P . I would appreciate it very much
