Re: Resurrecting my 56’ Patrician

Yesterday I used what remained of the radiator to mock up improved mounting brackets to move the radiator an additional ¾” away from the fan. And added rubber isolators to reduce vibration. Ordering another radiator tomorrow. There has been a nagging question of mine from the beginning. Does the ultramatic work? Yesterday I could not help it, I pushed the button, and it went into drive. However, it will not go back into park or neutral. Hence the car is 3 feet forward of where it has been for a year. Today is rain and a good day to familiarize myself with the electrical side of the pushbutton system. I have two wiring diagrams that the only difference I note is the existence of a transmission control relay in one and the other has those circuits running through the automatic park relay. The previous owner has butchered those wires with wire nuts. When I removed the relay, I noticed it is cracked in half underneath, guessing why it was bypassed. I came across a bulletin about bypassing the automatic park relay. Honestly, I would like to have that function. I have noted the electrical path for P, N, & R travels through a pressure switch. I am assuming this is a brake pedal switch. How many amps are these relays rated for (could not find it in the manual) and what is a decent replacement if any, for the automatic park relay?
