I took off the valve body, disassembled it, cleaned it and put it back together. I could not have done this without the various manuals that i found on line thanks to this forum. Well now it goes in reverse and actally shifts up, but i have other problems. When i start it in P then move the lever to N, I can't then go back to R or P unless I shut the engine off. Also, sometimes it stays in a forward gear when the lever is in N. I'm about to give up, unless someone can tell me it's somethiong simple that I now have to do.
