Wanted a 4l80e controller

Otis,

Check these guys out. I talked to them at SEMA. They have the stand alone controllers, but they also have a valve body that converts the 4L80E to a 5 or 6 speed and paddle shifters! All the gears are already there. It looked to be an easy conversion.

Transgo also offers a vacuum controller kit.

I have a Baumann Optishift - I was going to use it on my build, but went with a 6L90E and paddle shifters.
