Explorer 92 automatic transmission problem

Hello, greetings, I have a problem with an automatic transmission The model of the truck is as follows:

Ford Explorer 92 4x4 4.0L

American

air I tell you what happened:
I was driving normally and suddenly stopped moving the truck (that is, although it accelerated the truck did not move in any way, with no change), with the impulse that I took the parking The engine did not start.
It turns out that the zipped was broken and I thought that this was the whole problem, when changing it, I went to the truck and ignited but does not move by applying any change or reverse.
I checked the oil level, and all good (although the oil had a slight burn smell and was dark brown).
I lowered the transmission and when I opened it, I discovered that the overwater band was released, in addition the reversa dump cover had a loose screw (I thought I had found the fault).
In addition, the overmarcha planetarium was damaged.
I proceeded to do the following:
- I gave service to the servos (there are three)
- I changed the overmarcha and direct band
- I changed the planetarium
- I changed the converter
- Service was given to the entire mechanism (cleaning, greased)
- I changed the discs of the overwhelm clutch
- I assembled, mounted and put your oil

when you go on, but again it does not move in any position ...

What can be the problem? I lacked something? I lowered the service manual and apparently everything was done well, please help me .... Thank you very much.
