    Driver told me cruise stayed the same when he pushed brake, speed up when pushed clutch. In shop I tried to duplicated. Cruise shut down when both pedals pushed with no issues repeatedly. Set and excel positions work. Driver on drugs or has anyone had this issue? (LOL) Cruise is used mainly to control speed while using PTO. (water truck application) Thanks for any help!

    If possible, go for a ride with the driver and have him duplicate the symptom. I bet it would shed some light on the issue.
