This is a short video of how I adjust my overdrive and lockup automatic shift points with adjustable pressure switches.
Those relays on the firewall are what actually handles the electrical load.
The adjustable switches tell the relays to close and ground the solenoids to make the shift.
Is that a separate kit you have to get for controlling the OD and lockup? I want to put an A-518/46RH into my '72 D200 at some point and I like the adjustability of that setup.
