Check Gearbox Light

My son has purchased a Saab 900 1995 2.3 Automatic. The check gearbox light comes on after sitting at a stop light and when you go to take off, the car moves but 1/2 to 3/4 throttle is required to make it go. This does not happen all the time. When it does you can stop the car, shut it off and restart and the transmission works normally. The car has also had the light come on while at speed and if you slow down it will act like it has a slipping clutch again. We let the car sit for 1 hr and then the car performs normal again.

We changed the tranny fluid and has not changed the symptoms.

The gear selector has to be solidly in the detent gate or it will slip and have the gearbox light come on.

Does any one have any information on what this is?

Greatly appreciated.
