Welcome to the forum missouri100.
There was some dicussion in recent months about add-ons to ports
although I believe it was for temp. Do a search and will likely turn up.
I am curioous to hear why you are making your own controller.
How far have you got with that ?
My thought would be that on the 80 the crowding and risk to damage
would be a little more than the 60. Plan on putting an electrical sensor
on it or running oil to dash/controller ? Scale would have to be upwards of
325psi to handle reverse conditions even if fwd is nowhere near that.
Have you considered getting a combination of tran temp and pressure
control solenoid inputs to make yourself a "health meter" of sorts.
Notice you have machine noted, are you good with electronics too ?
Does this mean you are firing your ECM or is this a shift kit deal ?
Figure how to let ECM know what's happening ?
What ever it is you decide, and whatever stage of it you're in,
be aware this place loves pictures of these cool projects.
