Showing items 1 - 7 of 7 results.
I might be late to the party but make sure the dash shows the correct model number and not a C40L or something else.
Also, make sure the battery is good. If they are constantly jumping the truck or starting the engine off a battery charger that can cause premature failure of the sub-controller.

If that controller is the "Transmission Sub Controller" had issues with no up shift with that and found wiring loose pins in plug. Clark may have an update? You may have to contact Clark directly.
Also, have had some problems with poor grounds and ripple voltage from the alternator in the past causing frequent electronic component failure.

Fact of the week
The use of "hello" as a telephone greeting is attributed to Thomas Edison. He is said to have suggested it as a simpler alternative to other greetings, such as "Do I get you?" or "Are you there?".
