Anyone have any ideas on where to tap into to install a 2nd gear pressure switch (200-4R, of course)? I could put a boss on the servo cover and put it there, or on the 1-2 accumulator housing. What would be nicest is to tap into one of the crossfeed passages on the valvebody, but I can't figure out where.
Here's my idea: I'm running a Motec in my 66 GTO and would like to set up an input telling the ECU when the trans shifts so that it can take out, say, 30 degrees of ignition timing for a couple hundredths of a second to minimize shock loading to the trans. This is essentially what every modern driveline does. This should increase clutch life and hard part reliability substantially while sacrificing only a couple hundredths in performance.
The way I'm thinking this will work is, as the clutch starts to engage, it trips the switch, and completes engagement under reduced engine power. Granted, this will all happen in a few hundredths of a second and may not work at all with the ECU in a "passive" role. Seems like a good idea, though.
