No, the garmin servo is for the autopilot, it can however control the trim
servo for you to autotrim. It also controls the trim speed I believe.

Bob,
Tell me more about this feature in the Trio - I happen to have a Trio Pro w/autotrim
and am not aware of this.

Easy Cheap Dependable fix.
1) Replace your "Flap Toggle Switch" with a Double Pole (on) off on
switch. (Same as original but Double Pole)
2) On the 2nd pole (not controlling your flaps) install a single pole
double throw "Relay".
Install the relay so when your flaps are in the -3degree
position (Cruse position) the relay is activated.
Any other position "Off" (On) climb out or landing configuration the relay
will not be energized or normally closed.
3) Split the 14v power to both legs of the relay (Line side of the
relay) "Normally open and normally closed legs of the relay".
4) On the "Normally Closed" (1st leg) pin on the relay (Load side of
the relay) run your 14 volt power through the closed contacts,
You now have full power to your trim motor.
You will need full speed trim for takeoff and landing configurations.
5) On the 2nd leg of the relay (load side) the relay hook up a 9 volt
7809t voltage regulator with a capacitor.
Connect the 9 volt wire to the 14v wire on the (LOAD SIDE OF THE RELAY) that
connects back to your trim motor power.
Now when you are in the -3 Degree cruse position the relay is activated.
You are now feeding your trim motor with 9 volts and this will slow your
trim motor down enough for "Fine Feathering".
6) So when your flap switch is in the Off or (ON) position your relay
will be closed and feeding 14volts to the trim motor.
When your flaps are in the ON position (Normal Cruse -3 degrees) your relay
is active and switches the power to 9volts for your trim motor speed
reduction.
Works like a dream.
Costs about $20.
$10 for the Double Pole On Off (ON) toggle switch
$5 for the 12v/14v relay (Fog light, horn, etc relay) Checker auto
$3 for the voltage regulator Radio Shack or Fry's
$2 for the capacitor Radio Shack or Fry's
Optional computer fan 3 wire plug to plug the voltage regulator into for
easy termination $.99. Radio Shack or Fry's

The set up for the Trio pitch trim is described on page 60 of the Trio manual (you
can download it from their web site). In the set up, for example if you put
TL=18, TH=06, LAS = 60, HAS = 170; Then the trim will run at speed 18 (almost
max speed) when the airspeed is 60 or less; it will run at speed 6 (slow) at
speeds of 170 knots or more; and in between it is linearly extrapolated (e.g.,
at 115 knots it runs at speed 12).
IF YOU SET the speed to less than 4 the trim function is turned off.
To access the manual function, just boot up the autopilot, set the altitude as
normal, then push the right hand (vertical) function button. The display should
say "manual trim". (If it doesn't, cycle thru the vertical functions by pushing
the V button). Turn the rotary knob clockwise to trim up, counterclockwise
to go down.
Note: if you have multiple trim control switches (like the top hat plus the autopilot)
then you need an isolation system (either a hard switch or relays) which
allows the autopilot trim signal to go "straight thru". It uses pulse width
modulation which is too high a frequency for a relay to follow. I built my own
relay board using Digikey parts.
Personally I love this system, I don't know why Trio doesn't advertise it more.
I have never been able to smoothly trim in cruise with the top hat, just because
of the force I put on the stick when trying to use the top hat. I have my
autopilot near the top of the stack, but easily reached with my right hand.

A few thoughts.
I like to cruise with the flap switch in the off position, but your set up requires
one to leave it in the up position. If the flap limit switch fails the flap
motor will run continuously.
If one desires to take off with no flaps (-3 reflex) he has to put the switch in
the off position - opposite of cruise. My point is, there are operational choices
to be made, so this is not too different from just putting in a dedicated
trim speed switch.
I found it difficult to slow the trim as much as I would like, using just lower
voltages, without using voltages so low that the trim motor would stall. Since
you've already got some electronics there, for just a few bucks more you could
put in a pulse width modulation system and adjust it to go as slow as you like.

You dont have a separate "Cut off switch" for flap motor?
Put it in the Minus 3 position then turn it to off (center position) still
works at full speed...
It is On "top position" Off "Middle position" (On) "bottom position."
It stalled because you didnt use a capacitor...
And if the Pulse Modulator fails?..
I like the KISS plan...
Keep it simple...
