Hi just finshed Auto conversion and having trouble

i need to check the PCM, plugs and all wires from PCM to Transmission (4l60e)
iīm getting pulse (rattle) to the 1-2 solenoid and the transmission is not working correctly, it doesnīt take the 1st gear or like it stuck between gears or in two gears at the same time.
and when i put it in D it starts in 4th
in 2nd it starts in 2nd and 3rd is just 3rd
but i can manual shift it from 2nd to 3rd and 3rd to 4th
the valvebody was take out and the solenoids work correctly on the table , so it is like the problem is in the harness or PCM
i rechecked all wiring i installed , got a RPM jumper harness and then Reflashed the PCM to tell it itīs AUTO

i donīt have a service manual , itīs not sold here in Iceland

i need to know what signal iīm looking for from each pin/wire
if you donīt know what i mean , i mean like what pin/wire sends ground signal , what signals V and what signals pulse.

do you guys have any chart what so ever you could send me camarof1@visir.is or maby know where i can find these informations on the web.

thanks
Baezi
