Code 64 is a general code for the Electronic Clutch Actuator fault. It breaks down into 3 further different codes of possible failure for the ECA. This is why you have to get it scanned. One code is for loss of power, another code is no communication with it, and the third is mechanically not responding. The ECA is a high failure item in those. I believe they are covered under the transmission warranty which is 5 years on most highway trucks. If your truck is less then 5 years old, I recommend taking it to an authorized Eaton shop for repairs.
