Has.anyone run a zf4hp24 without an ecu or another box?
I want to run without the ecu and just use paddle shifters to operate the ds. You can use R N and D (in third) without 12v power.
I'm trying to find out about line pressures and the lock up function on the 3rd solenoid. I've come up with a solution to run the box as a sequential box with paddle shifters but need to understand the effect of line pressures and why I'd need to run the solenoid psych with a pen signal.
Also, jag used them, as far as I can discover the cases are all the same, just bell housing and tails hafts are different. Would anybody know if the input shafts are the same length too?
