Were the other transmissions of that era as dependent on hydraulic pressure as the Ultramatic?
Good question. 54 Cadillac manual has a whole page of Hydramatic pressures for various axle ratios and speeds and shift points but only show a single gauge as their tool -- not the 3 gang.
Whether that is due to not being as reliant on pressures and combinations or just that their mechanics could do them one at a time because of easier access is unknown.
With Packard you had to hook up a couple of places inside the pan using the special pan extension. Perhaps the 3 gang is as much for convenience so as not to drain the oil and drop the pan each time a new pressure was needed.
