AUTOMATIC TRANSMISSION
This kit says it’s for a lsx 454 with an automatic transmission. This will NOT come complete. You will have to order another harness and control module for the transmission. You do NOT see this information on any website anywhere! The kits may differentiate between the different automatic transmission options available. GM performance strongly suggest a 4L85E behind the LSX 454 due to torque output. Tom at crate engine depot will set you up with the correct transmission harness. The site has been updated to clarify the usages of this module.
