Auto Tranny Issues?

[jbjorndal]

I have a 88 toyota supra turbo with an auto tranny. I recently got the car from a friend and have not had much time to work on it. The engine smokes but seems to be strong so i think im going to change gaskets and stuff for now. But the tranny is a whole nother story... I put it into gear and no matter what it is in drive. When i drove it for a short period it would shift gears normal but no reverse. It also surges really bad. I was hoping that maybe these problems could be something simple like the shifter is loose and maybe the tranny surges because it needs a flush. The car sat for several years in a field. Hopefully someone has had similar problems or knows something that might help so i dont have to get a new tranny. Thanks for the help.
