    Zf4hp24 electronic gearbox

    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?

    hi jeff, from what i found out the x300 with a 3.2 straight six had the non electronic version (4hp22) which needs no 'majic' to work. the 4hp24 that you have was behind the 4.0 from memory. maybe source the 3.2 box instead? neil.
    need a job done on your project? i may be able to help.
