ZF4hp22 differences from different models/years
I'm trying to sort out the differences in transmissions between the various models/years that used the zf4hp22
My project needs a ZF where the torque converter feet sit +/- 50mm back from the bellhousing face. Seems like that means I need one that was mounted to a 3.5l v8 or 3.9l v8.
The one I have in my garage(which was a bargain at 20$!) has a torque converter that sits 27mm back. (checked on ashcroft site vs the box code and 27mm is the correct depth)
What I'm trying to get my head around is what these various boxes is different?
Is it simply the size of torque converter that shipped with them?
Are there certain parts that could be replaced to give me the depth that I need?
What about mounting points, Are the mounting points for the engine and trans the same between the 3.9 v8 trucks and the 4.0 v8 trucks?
Any info would be appreciated
