My wife's stock 98 gtp with 200k lost 4th gear, so I've got another trans to swap with it. I'm going to throw in a rebuild kit along with a hardened 4th clutch hub, and solenoid kit. What's the consensus on replacing the torque converter? And where do you guys get a good stock replacement? Anyone ever use the ones being sold on ebay? I'm thinking it's good insurance, but wanted to know what others do. Thanks.
