Rep Power: 659

Just picked up a 96 GSR. When it was picked up it drove beautifully. Got it to our shop and the next day when it was started up it would not go into gear. When the car is off it goes into gear easily. If the car idles for a few minutes then it goes into gear easily like brad new. Drained fluid and put in fresh fluid (albeit not Honda MTF), and still the same problem. Bled clutch and nothing. If car is started in gear it does not lurch or anything, acts perfectly normal untill it comes out of gear and problem persists.
Anyone run into anything like this??
Pulled the tranny and clutch seems fine, as does pressure plate. release bearing has a partially broken tab that hold it onto the release fork.
