From my experience, I could not tell you about the n/a awd trans. but i have been daily driving a FWD 1g dsm with a stock 90 AWD DSM trans without an issue. Just to make things stick to the ground better, I used a AWD Flywheel and Clutch kit. It's been 3 years and no problems on the drivetrain. I even left the transfer case output shaft in the trans. Granted first gear acts like its not there, but it work.
