Zf4hp24
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 with a pwm 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? Can I use. P38 bell housing and convertor or do I need to use a p38 box with 2wd tail housing?

Does anyone know the solenoid sequencing on the zf4HP24 gearbox?
I'm going to run the box with a PLC and have it fully sequential using the TOSS signal to lock up the torque converter as well and for the speed.
I just need to figure out how the solenoids operate to give you which specific gear. Once I got it working I'll post a how to thread up
