Per the tci auto website where they have good instructions
on setting the tv pressure -
they say to use a ~.400" thick gauge block for the carb
tv cable setup, but neglect to say whether or not it's
the same thickness for the efi setting.. It is.
I used a short chunk of 7/16'" bolt and using a hacksaw
(hi tech here ) cut a lengthwise slot in it down
the middle which is just about the right width to fit over
the inner/cable part of the tv cable "beyond" the adjuster
thingy at the throttle body, and behind the ferrule at the end
of the cable.
I got a decent oil pressure gauge with a fairly wide sweep
to the needle so I could tell pretty closely what pressure I
had and the 3/8" pipe threaded adapter screwed right into
the correct port on the AOD (again, see the TCI website for
a sketch for the right port/plug on the pass side)
Tough to get at.
Follow the directions. For just a little higher rpm and firmer
shifts, set it closer to 40 lbs than the factory 33 lbs.
I screwed in a short nipple and (45 el if you can find one)
elbow so it's easier to get at the next time you do this,
then put the original plug in the elbow to seal it.
Run the engine till the trans fluid is lukewarm like the
directions say. Put the gauge up on the pass side wiper
so you can see it, put the trans in neutral and hold the
brake, and see what you've got. Adjust accordingly.
If the shifts are too soft and early, adjust higher one
notch at a time on the adjuster. If they're too high rpm
and hard, adjust lower one notch at a time. Basically,
you want no slack in the inner cable when the throttle
body is at full lowest warm idle position, at least as
a starting point. best to use a gauge and go thru
