transmition problems?

I have a 95 eagle talon tsi awd with an auto transmition and i started having problems with the transmition, at first when i put it into drive the gear slipped a little before driving.Now the car dosent drive in any of the D 1 2 gears but reverse works perfectly.

does anyone have an idea what the problem could be?

go figure...its a common fact that dsm's have bad trannys.
