My CAT 236B keeps going into park mode. I bought it in '05 and now when driving it, the brake will activate and it goes into park mode. Hit release and it's okay for a couple of minutes. Could it be a bad safety switch? Mechanic doesn't know much about it. Seems like a common issue.

Not sure how these work for the brake, but it could be a bad hold coil? If it's coming off, I would doubt it's the computer. I would suspect a solenoid or even a bad connection.

Check the wiring connections to the parking brake solenoid. Sometimes corrosion or a loose connection can cause intermittent issues.

I had a similar issue with mine. Turned out to be a faulty seat switch that was intermittently disengaging.
