transmission, pedals, gear lever, etcetera. I'm not sure if the 93 GLI AT already has slots ready for the clutch pedal or if you have to cut holes in the firewall for it. Cost will depend on the cost of the transmission and whether or not you can sell the old one to offset the costs.

I'm thinking 6-10k for labor? Not sure, because most shops don't want to commit to this kind of job, and they'll tell you it's easier to just re-sell and buy a manual version instead.
