Thanks for the comments guys. Work's been crazy, but I had to get back over here.
UPDATE:
The new 4L80E transmission is in, and it feels great. It has a B&M shifter and a new Circle D Multi Disk torque converter. There are two ways to lock the converter. You can either use the button on the handle (have to hold it down), or you can use a switch on the center console for the highway.
I'll post up some pics later.
She's all ready for the LSX.
