I've got an '02 F-350 Dually PSD, R400 tranny. Just got my truck back today with the brake installed and gave it a couple of tests on downhill grades with no load. I disengaged overdrive on the F350, allowed it to go into high gear, and turned on the brake. It worked, but on the second test I noticed the orange light that indicates OD is off began blinking. I turned off the brake and it blinked until I held the button/switch in a few seconds. I did not give it time to see if OD was engaging thinking I'd ask here before going further. Any thoughts? Anyone had a similar event? I'd add that the brake was installed by a large truck mechanic at a large truck dealer and coincidentally he just installed the same brake in his 7.3 a couple weeks ago.
Good idea. I know the older Ford cruise control switches in the steering hub had a similar problem. Before I go into the column I'll use the OD button without engaging the brake and see if I get a similar reaction. Thanks.
