747 swap - TCC control using kick down output from ECM

[Marc Piccioni]

See my other post in answer to Dave C's question. If the trans. kicksdown 
to 2nd gear the TCC unlocks. I agree that a manual switch is a good idea. 
Lots of big hills nearby ( 1 hour from the Rockies).

That's more reasonable to use with your relay than other tcc schemes.
Does converter clutch unlock with load increase?  Maybe manual switch
inline for hills, if the local topography includes them.  I used to
drive up the hills with the brake pedal ever so slightly depressed to
disengage tcc (83 Phoenix 2.5l).  Side effect was brake lights on, of
course.  Wonder what other drivers thought of me. <g>
