I would have it rebuilt and install it with a new torque converter. Parts and labor should be around $1600. You can pull it and reinstall it and save 400 or so....

new torque convertor?  is there a better option than the one thats in there?  also im not sure how to go about rebuilding it if its a "special" tranny for the turbos maybe its not possible with rebuild kits out there etc? wanna weigh all my options and money is a concern.  i can afford the $350 used one but not a $2000 rebuild:)........scot

I rebuilt mine with all the latest updates, "Red" clutches, Phantom Grip LSD, & a 500 rpm higher stall, cost me around 1K

We did about the same, no LSD and 1,000 rpm higher stall, of course that was for a built engine, hopefully the stall isn't going to be too high for the stock engine.  The bigger turbo will hopefully be big enough to need the higher stall.
