4l80 in a lt1?
You can have it built with a reverse-pattern manual valve body, P-R-N-1-2-3-4, or run it fully automatic with an aftermarket controller like the TCI Transmission Control Unit. This controller has a manual mode where you can do manual gear changes with switch paddles. (not included) A crossmember will need to be built and torque arm provisions made.
The flexplate for those should be dual-pattern. Look for the larger bolt circle.
