the trans itself is actually pretty simple....
the control of the trans is actually pretty simple as well...
but making something that properly controls the trans is the issue...
the real issue is that the 6L80 just isnt made for any serious power
and you need all the "torque management" to keep the thing from breaking
programming the torque management requires some feedback from the engine pcm itself and also some response back to the engine PCM
that is the part that makes it tough to do...
there are plenty of controllers that could change the gears and do the pressures correctly....
but that transmission breaks easy without any fine tuning control... which is all done via canbus and the TCM in the sump area of the transmission itself
all you would have to do is supply a kit to bypass the internal tcm and suddenly you have a standard valve body transmission...simple solenoid control is all it would be at that point..
(and I know theres more to it than what I just said.... it would be quite an expensive task to make a custom bypass harness just to use a separate trans controller)
