Controller is 1988. It has mechanical switches for slow down and final that cam on car hit. And also has like the u shaped magnetic switches on car that go thru flat metal camS at the landings .. it has 2 very short floors. Including the top 2 landings. They are a few feet apart front and rear openings

You might need a helper to run the car for you while you watch the up sequence of events on the failure. Have you ruled out the traveling cable?

I had an HMC-1000 doing something similar. Directional limit was right at floor level. You’d get to the floor fine, doors open, close, then MLT. Might make sense if your directional limit only drops the valves, not the motor.

Front and rear opening a few feet apart at the top floor(s).
* So does this unit see a high speed demand from short floor to top (5 to 6)?
*Is there a metal fin (vane) which drops high speed to top floor and transition to level speed? If so, maybe move it up a few inches, but be sure to mark the original position.
*Is there another adjustable timer just for leveling duration or time?
*Dirt makes a good point about the up stop limit. Check it out.
