Humm, one of these days I'm going to seriouly investigate my paddle shifter
theory.
Theory: The TCM tells the computer (and hence the truck) when to shift and
which way. Now this must me done with some sort of simple electrical signal
pulse or change. Now what's stopping some one from intercepting the TCM to
PCM connection. Say intercepting it with a paddle shifter set up. e.g. why
can the manually operated paddle shifters send the electric signal insted of
the TCM?
Oh well, we'll figure it out sooner or later.
