No I don't . I know very little about them. I managed to bust an oil pump
that is the thing that the torque converter fits into. It supplies oil
pressure to the control valve assembly. I had what is described as a box full
of neutrals also.
The ZF3HP22 manuals list the following possibilities for a box full of
neutrals:
oil level too low
shifter adjusted incorrectly
oil pump not operating
main pressure valve sticking in released position
drive plate broken ( this would make it impossible to start the engine)
parking pall seized
defective A and B clutches
input or output shaft broken
This final cause is usually the result of an accident
