Wow, your posts are incomprehensible.
But from the bits I could understand, I am going to go out on a limb and say the transmission needs to be completely rebuilt/replaced. Clue #1, you said the fluid was black, or at least fluid and black were next to each other in your post. This is a sign that the transmission has been slipping for a long time, getting worse and worse. That will not only damage the band or clutch which is slipping, but overheat the fluid and cause all the other soft parts to wear excessively/overheat.
An automatic transmission works by apply different bands and clutches to change the gear ratio. If one or more of the bands/clutches doesn't get applied because of a bad valve body (or more likely in your case, a worn or broken band/servo/clutch), then you wouldn't get the gear called for, but an entirely different gear, depending on what is applied. That is likely the reason you are getting reverse, when first gear is applied.
Bottom line, the transmission needs to be entirely rebuild or replaced. Doesn't matter what's wrong with it, everything needs to be inspected, checked and wear parts replaced. To reduce the cost, you may consider a j-yard trans, especially since you seem able to do some basic labor on your own.
