Saab Transmission help.

[ned2683]

A friend of mine called to look at her car, it is a 86 Saab 900 (automatic). she was driving it and suddenly it won't catch any gear. its been having a problem slipping into 4th.

so i arrive there and she turns on her car. it idles fine, and as soon as she puts it in drive or in any gear i hear a clunking kinda like how an unbalanced dryer is. then when she puts it back to Park i hear a grinding sound. and it won't lock the trans up (u can still push it)

I told her it sounded like the torque converter got knocked loose, and was spining around in there. so it should be jsut that to replace. what do u guys think it is?
