As the title says, i'm selling my 2000 GSR transmission for $450, NO TRADES. I replaced both axle seals, cleaned it up and painted it with aluminum engine paint back in August. It shifts very smooth and has zero grinds. I baby the hell out of this thing.
I also only run Synchromesh fluid in it. It will be available this weekend (01/21/12) when I take it out of my car. The only reason it's coming out is because i'm getting a better one.

Here is a picture of it back in August when I had it out. PM me if interested.
